A Resource Guide to Change Concepts

A RESOURCE GUIDE TO CHANGE CONCEPTS

While all changes do not lead to improvement, all improvement requires change. The ability to develop, test, and implement changes is essential for any individual, group, or organization that wants to continuously improve. But what kinds of changes will lead to improvement? Usually, a unique, specific change is required to obtain improvement in a specific set of circumstances. Thus, there are many kinds of changes. But these specific changes are developed from a limited number of change concepts.

A concept is a general, abstract notion that is applied through a more specific idea. A change concept is a general notion or approach to change that has been found to be useful in developing specific ideas for changes that lead to improvement. Creatively combining these change concepts with knowledge about specific subjects can result in developing changes that lead to improvement. Many change concepts can be used to develop specific changes that do not require tradeoffs between costs and quality.

This resource guide enumerates the change concepts that have already been discussed in this book, as well as others that readers will find useful. The use of change concepts was introduced in Chapter Five, and examined more specifically in Chapters Ten, Eleven, and Twelve, in the discussion of the three categories of improvement. This resource guide organizes these ideas in one place for ease of reference and use.

The seventy change concepts listed here are organized into the following nine general groupings:

How to Use the Change Concepts

The change concepts presented in this resource guide are not specific enough to be applied directly to making improvements. Rather, the concept must be considered within the context of a specific situation and then turned into an idea. The idea will need to be specific enough to describe how the change can be developed, tested, and implemented in the specific situation. When describing the change concepts, we have tried to be consistent in the degree of specificity or generality of the concepts. Sometimes, a new idea seems at first to be a new change concept; but often, with further thinking, it is seen to be an application of one of the more general concepts.

We make no claim to have included all of the useful change concepts that exist. As you use this resource guide, try to develop more concepts. One way to discover concepts is to study the improvements that have recently been made in your organization:

1. What was the specific change that was made?
2. What was the idea used for the change?
3. Where (who) did the idea come from?
4. Which of the change concepts could generate that idea?
5. Can the idea be generalized for other situations?
6. Would a new concept be useful to describe this idea for change?

The primary purpose of this resource guide is to provide help to individuals and teams who are trying to answer the question, What change can we make that will result in improvement? The change concepts can serve to provoke a new idea for an individual or team. A team leader can choose one of the change concepts and then the team can explore some ideas for possible application of this concept to the situation of interest. The list of ideas should be recorded. After the generation of ideas is complete, the ideas can be discussed and critiqued. Any of the ideas that show promise can be further explored by the team to obtain a specific idea for a change.

How is a particular change concept selected for focus in a session to generate ideas? The aim of the improvement effort will provide some direction. The following are some ways that have been found useful:
1. Choose a change concept that someone on the team thinks might generate some ideas that would be useful to the aim of the improvement. effort.
2. Choose change concepts that have not been previously considered by the team.
3. Select one of the nine categories that is related to the aim of the improvement effort. Then randomly choose one of the change concepts in that category.
4. Randomly choose a change concept from the list of seventy.

When a concept is randomly selected, more creative ideas can be expected to come from the session because people might get further away from their usual thought processes. Conversely, it might take a long session before the relevance of ideas from a randomly selected concept is discovered. A concept, or concept category, that is obviously relevant to the aim of the improvement effort can be expected to yield a higher number of useful ideas in less time, but it may not generate a completely new approach to the activity of interest.

Some of the change concepts appear to offer conflicting advice for developing changes. For example, concept 25, “reduce choice of features” (in the Optimize Inventory category), and concept 63, “mass customize” (in the Focus on a Product/Service category) appear to be aimed in opposite directions. Change concept 4, “reduce controls on the system,” and change concept 51, “standardization (create a formal process),” also suggest conflicting directions. The important consideration is the context in which the change concept is being considered.

For example, if an organization is trying to change the expectations of its satisfied customers, asking the customers to do additional tasks associated with the product or service they are purchasing might not be of interest. However, if an organization is trying to reduce costs while maintaining quality, a customer might be willing to take on some additional work that is easier done at the customer’s site if that would lead to significant price reductions. It may be appropriate to increase options to a customer who values the choices (who is willing to pay a higher price), but customers who want to minimize their costs for a product or service will appreciate the efficiencies that can come from reduced choices. Standardization is appropriate for high-leverage processes, but may be overkill for processes that are not leverage points for costs, capacity, or quality. Table A.1 lists some guidelines for considering some of the change concepts that may lead in conflicting directions. When using a change concept to develop ideas for a specific change, understanding and knowledge of the particular circumstances will always be the determining factor concerning the appropriateness of the concept.

The Change Concepts

A. Eliminate Waste

In a broad sense, any activity or resource in an organization that does not add value to an external customer can be considered waste. Some examples of waste are materials that are thrown away, rework of materials and documents, movement of items from one place to another, inventories, time spent waiting in line, people working in processes that are not important to the customer, extra steps or motion in a process, repeating work that has previously been done by others, overspecification of materials and requirements, and more staff than required to match the demand for products and services.

Toyota is famous for focusing improvement on the following seven wastes:

1. Waste of overproduction 5. Waste of stock (inventory)
2. Waste of waiting 6. Waste of motion
3. Waste of transportation 7. Waste of producing defective
4. Waste of processing itself products

The following eleven change concepts are included in this category:

1. Eliminate Things that Are not Used
2. Eliminate Multiple Entry
3. Reduce or Eliminate Overkill
4. Reduce Controls on the System
5. Recycle or Reuse
6. Use Substitution
7. Reduce Classifications
8. Remove Intermediaries
9. Match the Amount to the Need
10. Use Sampling
11. Change Targets or Set Points

1. Eliminate Things That Are Not Used
Constant change in organizations results in less demand for specific resources and activities that were once important to the business. Unnecessary activities and unused resources can be identified through surveys, audits, data collection, and analysis of records. The next step is to take the obvious actions to remove the unused elements from the system.

2. Eliminate Multiple Entry
In some situations, information is recorded in a log or entered into a database more than one time, creating no added value. This practice is also called data redundancy. Changing the process to require only one entry can lead to improvement in productivity and quality (by reducing discrepancies). Recent technology developments (such as optical scanners) make it possible to enter data directly from sight or by voice. Once data is recorded, there should be no reason to reenter the same information at a later time.

3. Reduce or Eliminate Overkill
Sometimes, a company’s standard or recommended resources are designed to handle special, severe, or critical situations rather than the normal situation. Changing the standard to the appropriate amount of resources for the normal situation will reduce waste. Additional resources would be used only when the situation required it. A common reaction in many organizations to a special problem is to add more resources to the process, product, or service so that the problem will not occur if the special situation occurs again. While this can be effective in solving quality problems, the result is often overkill, amounting to higher costs and lower productivity each time the process is run, the service is conducted, or the product is produced.

4. Reduce Controls on the System
Individuals and organizations use various types of controls to make sure a process or system does not stray too far from standards, requirements, or accepted practices. While useful for protection of the organization, these controls can increase costs, reduce productivity, and stifle improvement. Typical forms of controls include a layered management structure, approval signatures, standardized forms, and reports. A regular review of all of the organization’s control procedures by everyone working in the system can result in identifying opportunities to reduce controls on the system without putting the organization at risk.

5. Recycle or Reuse
Once a product is created and used for its intended purpose, it is natural to discard it and the by-products created by its use. However, if other uses can be found for the discarded product or by-products, the cost of producing the product can be spread out over its use and its reuse. As concern about the effect on the environment of the disposal of materials becomes more critical, organizations will be reassessing the costs associated with throwing away materials. Many times, recycling will be found to be a cost-effective alternative. Design engineers in most manufacturing companies are learning how to “design for disassembly.” New products can be designed as components or modules, with a plan for reuse. Computer programs can be developed from a set of modules of computer code that perform specific tasks such as sorting data, plotting data, and so on. Scaffolding at a construction site can be designed for easy disassembly for reuse at the next site. The ease of destruction of a product is becoming just as important as the ease of construction.

6. Use Substitution
Waste can often be reduced by replacing some aspect of the product or process with a better alternative. One type of substitution is to include lower-cost components, materials, or methods that do not affect the performance of the process, service, or product (sometimes called value engineering). Another type of substitution is to switch to another process with fewer steps, less manual effort, and so on.

7. Reduce Classifications
Classifications are often developed to differentiate elements of a system or to group items with common characteristics, but these classifications can lead to system complexity that increases costs or decreases quality. Classification should be reduced when the complexity caused by the classification is worse than the benefit gained.

8. Remove Intermediaries
Intermediaries such as distributors, handlers, agents, and carriers may be part of a system. Consider eliminating these activities by linking production directly with the consumer. Some intermediaries add value to a process because of their specialized skills and knowledge. Often, however, eliminating these services can increase productivity without reducing value to the customer.

9. Match the Amount to the Need
Rather than using traditional standard units or sizes, organizations can adjust products and services to match the amount required for a particular situation. This practice reduces waste and carryover inventory. By studying how customers use the product, more convenient package sizes can be developed.

10. Use Sampling
Reviews, checks, and measurements are made for a variety of reasons. Can these reasons be satisfied without checking or testing everything? Many times, the standard 100 percent inspection and testing results in waste of resources and time.
Formal sampling procedures are available that can often provide as good or even better information than 100 percent checking.

11. Change Targets or Set Points
Sometimes problems go on for years because some piece of equipment is not designed or set up properly. Make sure that process settings are at desirable levels. Investigate places where waste is created, and consider adjustments to targets or set points to reduce the waste.

B. Improve Work Flow
Products and services are produced by processes. How does work flow in these processes? What is the plan to get work through a process? Are the various steps in the process arranged and prioritized to obtain quality outcomes at low costs? How can the work flow be changed so that the process is less reactive and more planned?

The critical-path method is one tool available to help coordinate flow in a process. Originally developed for project planning, the tool has been adapted to help synchronize work flow in complex processes in which time is a critical parameter.

The following eleven change concepts are included in this category:

12. Synchronize
13. Schedule into Multiple Processes
14. Minimize Handoffs
15. Move Steps in the Process Close Together
16. Find and Remove Bottlenecks
17. Use Automation
18. Smooth Work Flow
19. Do Tasks in Parallel
20. Consider People as in the Same System
21. Use Multiple Processing Units
22. Adjust to Peak Demand

12. Synchronize
Production of products and services usually involves multiple stages. These stages operate at different times and at different speeds, resulting in an operation that is not smooth. Much time can be spent waiting for another stage to be reached. By focusing on the flow of the product (or customer) through the process, each of the stages can be brought into harmony. Some of the changes that can be developed from this concept include the use of “just-in-time” inventory practices, batching (blocking) to organize multiple activities, the linking of parallel activities during the process, and the development of timing of events to match the predicted flow of the process.

13. Schedule into Multiple Processes
A system can be redesigned to include multiple versions of the same process focused on the specific requirements of the situation. Rather than a “one-size-fits-all” large process, multiple versions of the process are available, each tuned to the different types of needs of customers or users. Priorities can be established to allocate and schedule the inputs in order to maximize the performance of the system. The specific processes can then be greatly simplified since they only address a limited range of input requirements.

14. Minimize Handoffs
Many systems require that elements (a customer, a form, a product, and so on) be transferred to multiple people, offices, or work stations to complete the processing or service. The handoff from one stage to the next can increase time and costs and cause quality problems. The work flow can be rearranged to minimize any handoff in the process. The process can be redesigned so that any worker is only involved one time in an iteration of a process. Making changes in organization structure or position descriptions is one type of change that can be used to minimize handoffs. For example, layers of management that require multiple reviews, meetings, and approvals can be reduced; clerical jobs can be expanded to include scheduling, staffing, planning, and analysis; and workers can be cross-trained to handle many functions rather than be specialists in one specific function.

15. Move Steps in the Process Close Together
The physical location of people and facilities can affect processing time and cause communication problems. If the physical location of adjacent steps in a process are moved close together, work can be directly passed from one step to the next. This eliminates the need for communication systems (such as mail) and physical transports (such as vehicles, pipelines, and conveyor belts).

The result of moving steps closer together can be lower capital and maintenance costs, reduced inventory (especially work in process), and more frequent improvement (from better communication). If it is not possible to physically move steps in a process together, electronic hookups should be considered. For some processes, computer networks with common file structures can have an effect similar to physically moving the steps together.

16. Find and Remove Bottlenecks
A bottleneck or constraint is anything that restricts the throughput of a system. A constraint within an organization would be any resource for which the demand is greater than its available capacity. To increase the throughput of a system, the constraints must be identified, exploited if possible, and removed if necessary. Bottlenecks occur in many parts of daily life: when exiting a concert hall, when driving in rush-hour traffic, when dealing with a telephone receptionist or the cashier in a cafeteria line. Bottlenecks can usually be found by looking where people are waiting or where work is piling up.

17. Use Automation
The flow of many processes can be improved by the intelligent use of automation. Consider automation to improve the work flow for any process to reduce costs, reduce cycle times, eliminate human slips, reduce repetitive manual tasks, and provide measurement.

18. Smooth Work Flow
Yearly, monthly, weekly, and daily changes in demand often cause work flow to fluctuate widely. Rather than trying to staff in order to handle the peak demands, steps can often be taken to better distribute the demand. This distribution results in a smooth work flow rather than in continual peaks and valleys.

19. Do Tasks in Parallel
Many systems are designed so that tasks are done in a series or linear sequence. The second task is not begun until the first task is completed. This is especially true when different groups in the organization are involved in the different steps of a process. Sometimes, improvements in time and costs can be gained from designing the system to do some or all tasks in parallel. For example, the work on step 5 can begin as soon as step 1 is complete rather than waiting until steps 2, 3, and 4 are done.

20. Consider People in the Same System
People in different systems are usually working toward different purposes, each trying to optimize their own system. Taking actions that help people to think of themselves as part of the same system can give them a common purpose and provide a basis for optimizing the larger system.

21. Use Multiple Processing Units
To gain flexibility in controlling the work flow, try to include multiple work stations, machines, processing lines, and fillers in a system. This makes it possible to run smaller lots, serve special customers, minimize the impact of maintenance and downtime, and add flexibility to staffing. With multiple units, the primary product or service can be handled on one line to maximize efficiency and minimize setup time. The less-frequent products and services can be handled by the other units.

22. Adjust to Peak Demand
Sometimes it is not possible to balance the demands made on a system. In these cases, rather than keeping a fixed amount of resources (materials, workers, and so on), historical data can be used to predict peak demands. Then methods can be implemented to meet the temporarily increased demand.

C. Optimize Inventory

Inventory of all types is a possible source of waste in organizations. Inventory requires capital investment, storage space, and people to handle and keep track of it. In manufacturing organizations, inventory includes raw material waiting to be processed, in-process inventory, and finished-good inventory. For service organizations, the number of skilled workers available is often the key inventory issue. Extra inventory can result in higher costs with no improvement in performance for an organization. How can the costs associated with the maintenance of inventory be reduced? An understanding of where inventory is stored in a system is the first step in finding opportunities for improvement. The use of inventory pull systems such as “just-in-time” is one philosophy of operating an organization to minimize the waste from inventory.

Four change concepts are listed in this category:

23. Match Inventory to Predicted Demand
24. Use Pull Systems
25. Reduce Choice of Features
26. Reduce Multiple Brands of Same Item

Concepts 23 and 24 seem to offer two conflicting approaches to optimizing inventory. Matching inventory to predicted demand is most appropriate when cycle times for production or assembly are long. In these situations, it is not acceptable to wait until an order is received to begin production. The use of pull systems is more appropriate when production delays are short. Often these two concepts are combined to develop an optimum inventory strategy.

23. Match Inventory to Predicted Demand
Extra inventory can result in higher costs with no improvement in performance for an organization. How can the proper amount of inventory to be maintained at any given time be determined? One approach to minimizing the costs associated with inventory is to use historical data to predict the demand. Using these predictions to optimize lead times, order quantities, and so on will lead to replenishing inventory in an economical manner. This is often the best approach to optimizing inventory when the process involves lengthy production times.

24. Use Pull Systems
In a pull system of production, work at a particular step in the process is done only if the next step in the process is demanding the work. Enough product is ordered or made to replenish what was just used. This is in contrast to most traditional “push systems,” in which work is done as long as inputs are available. A pull system is designed to match production quantities with a downstream need. This approach can often result in lower inventories than a schedule-based production system. Pull systems are most beneficial in processes with short cycle times and high yields. Some features of effective pull systems are small lot sizes and container quantities, fast setup times, and minimal rework and scrap.

25. Reduce Choice of Features
Many features are added to products and services to accommodate the desires and wants of different customers and different markets. Each of these features makes sense in the context of a particular customer at a particular time, but taken as a whole, they can have tremendous impact on inventory costs. A review of current demand for each feature and consideration of grouping the features can allow a reduction in inventory without loss of customer satisfaction.

26. Reduce Multiple Brands of Same Items
If an organization uses more than one brand of any particular item, inventory costs will usually be higher than necessary since a backup supply of each brand must be kept. Consider ways to reduce the number of brands while still providing the required service.

D. Change the Work Environment

Changes to the environments in which people work, study, and live can often provide leverage for improvements in performance. Production of products and services takes place in some type of work environment. As organizations try to improve quality, reduce costs, or increase the value of their products and services, technical changes are developed, tested, and implemented. Many of these technical changes do not lead to improvement, however, because the work environment is not ready to accept or support the changes. Changing the work environment itself can be a high-leverage opportunity for making other changes more effective.

The following eleven change concepts are included in this category:

27. Give People Access to Information
28. Use Proper Measurements
29. Take Care of Basics
30. Reduce Demotivating Aspects of Pay System
31. Conduct Training
32. Implement Cross-Training
33. Invest More Resources in Improvement
34. Focus on Core Processes and Purpose
35. Share Risks
36. Emphasize Natural and Logical Consequences
37. Develop Alliances/Cooperative Relationships

27. Give People Access to Information
Traditionally, organizations have carefully controlled the information available to various groups of employees. Making information available to employees relevant to their jobs allows them to suggest changes, make good decisions, and take actions that lead to improvements. The development of Cable News Network’s (CNN) worldwide coverage in the 1980s is a good example of the power of information. CNN’s coverage of events lets people know what is happening throughout the world in real time. This change in television reporting changed the way people think about the world. People view themselves as a part of major events rather than as passive bystanders.

28. Use Proper Measurements
Measurement plays an important role in focusing people on particular aspects of a business. In many organizations, the things that are measured are considered important while the things not measured are considered unimportant. Developing appropriate measures, making better use of existing measures, and improving measurement systems can lead to improvement throughout the organization.

Many companies try to utilize measures that are not accurate or that are of unknown accuracy. Inaccurate measures lead people astray, resulting in tampering, ignoring problems, and so on. A study of the quality of measurement often indicates that the accuracy of many of the measures do not support the importance that managers placed on them each month. When more accurate measures are developed, everyone begins to treat the measures with more respect, and fewer changes have to be made to plans each month.

29. Take Care of Basics
There are certain fundamentals that must be done to make any organization successful. It is sometimes useful to take a fresh look at these basics to see whether the organization is still on track. If there are fundamental problems in the business, changes in other areas may not lead to improvements. Concepts like orderliness, cleanliness, discipline, and managing costs and prices are examples of fundamentals in any organization. Also, when people’s basic needs are not being met, meaningful improvements cannot be expected in other areas. The “Five-S” movement, which was the beginning of quality control in Japanese workshops, got its name from the Japanese words for straighten up, put things in order, clean up, personal cleanliness, and discipline.

30. Reduce Demotivating Aspects of the Pay System
Pay is rarely a positive motivator in an organization, but it can cause confusion and become a demotivator. Some pay systems can encourage competition rather than cooperation among employees. Another result of some pay systems is the reluctance to take risks or make changes. Review the organization’s system for pay to ensure that the current system does not cause problems in the organization.

31. Conduct Training
Training is basic to quality performance and the ability to make changes for improvement. Many changes will not be effective if people have not received the basic training required to do a job. Training should include the “why” as well as the “what” and the “how.”

32. Implement Cross-Training
Cross-training means training people in an organization to do multiple jobs. Such training allows for flexibility and makes change easier. The investment required for the extra training will pay off in productivity, product quality, and cycle times.

33. Invest More Resources in Improvement
In some organizations, people spend more than a full-time job getting their required tasks completed and fighting the fires created in their work. The only changes made are reactions to problems or changes mandated outside the organization. To break out of this trap, management must learn how to start investing time in developing, testing, and implementing changes that will lead to improvements. Some methods for focusing resources on improvement include substituting improvement for non-value-added work, using full-time “SWAT” teams assigned to a process or outcome, assigning positions in research and development to process improvement, using industrial engineers in service industries, and using relief operators, temporaries, or overtime hours.
.
34. Focus on Core Processes and Purpose
Why are people doing all of the activities that go on in the organization? Which activities are directly related to the purpose of the organization? These are the core processes. Core processes can also be characterized as those activities that provide value directly to external customers. To reduce costs, consider reducing activities that are not part of the core processes.

35. Share Risks
Every business is faced with taking risks, and their accompanying potential rewards or losses. Many people become more interested in the performance of their organization when they can clearly see how their future is tied to the long-term performance of the organization. Developing systems that allow all employees to share in the risks can lead to an increased interest in performance. Types of plans for sharing risks and gains include profit sharing, gain, sharing, bonuses, and pay for knowledge. Care must be taken with these types of programs. Companies can undermine workers’ job satisfaction and creativity by placing too much emphasis on extrinsic motivation from incentives. Systems must be carefully designed to keep everyone focused on the purpose of the organization and not just on the potential short-term gains.

36. Emphasize Natural and Logical Consequences
An alternative approach to traditional reward-and-punishment systems in organizations is to focus on “natural and logical consequences.” Natural consequences follow from the natural order of the physical world (for example, not eating leads to hunger), while logical consequences follow from the reality of the business or social world (for example, if you are late for a meeting, you will not have a chance to have input on some of the issues discussed). The idea of emphasizing natural and logical consequences is to get everyone to be responsible for their own behavior rather than to use power, judge others, and force submission. Rather than demanding conformance, the use of natural and logical consequences permits choice.

37. Develop Alliances/Cooperative Relationships
During recent years, many industries have gone through a period of consolidation, acquisition, and merger. Often the result is fewer and larger organizations in an industry, but not much effort to integrate the pieces into an overall system. Consequently, there is no increase in value to the industry’s customers. Various types of alliances based on the principle of cooperation to optimize the interactions between the parts of the system offer a better approach for integration of organizations.

E. Enhance the Producer/Customer Relationship
To benefit from improvements in quality of products and services, the customer must recognize and appreciate the improvements. Many ideas for improvement can come directly from a supplier or from the producer’s customers. Many problems in organizations occur because the producer does not understand the customer’s needs, or because customers are not clear about their expectations of suppliers. The interface between the producer/provider and its customers provides opportunities to learn and develop changes that will lead to improvement.
The following eight change concepts are included in this category:

38. Listen to Customers
39. Coach Customers to Use the Product/Service
40. Focus on the Outcome to a Customer
41. Use a Coordinator
42. Reach Agreement on Expectations
43. Outsource for “Free”
44. Optimize Level of Inspection
45. Work with Suppliers

38. Listen to Customers
It is easy for people to get caught up in the internal functioning of the organization and forget why they are in business: to serve their customers. Time should be invested on a regular basis in processes that “listen” to the customers. Sometimes, it is important to figure out how to communicate with customers further down the supply chain, or even with the final consumer of the product or service. Talk to customers about their experiences in using your products. Learn about improvement opportunities.

39. Coach Customers to Use the Product/Service
Customers often encounter quality problems and actually increase their costs because they do not understand all of the intricacies of the product or service. Companies can increase the value of their products and services by developing ways to coach customers and consumers on how to use them.

40. Focus on the Outcome to a Customer
Make the outcome (product or service) produced by your organization the focus of all activities. First, clearly understand the outcomes that customers expect from your organization. Then, to focus improvement efforts on a particular work activity, answer the question, How does this activity support the outcome to the customer? Make improvements in the quality, costs, efficiencies, cycle times, and so on of that activity. Organize people, departments, and processes in a way that best serves the customer, paying particular attention to the product/customer interfaces. This change concept could also be described as "begin with the end in mind."

41. Use a Coordinator
A coordinator’s primary job is to manage producer/customer linkages. For example, an expeditor is someone who focuses on ensuring adequate supplies of materials and equipment or who coordinates the flow of materials in an organization. Having someone coordinate the flow of materials, tools, parts, and processed goods for critical processes can help prevent problems and downtime. A coordinator can also be used to work with customers to provide extra services. One example of a coordinator is a case manager, who acts as a buffer between a complex process and the customer. The case manager must have the authority to get things done when the customer’s needs are not being met.


42. Reach Agreement on Expectations
Many times customer dissatisfaction occurs because the customers feel that they have not received the products or services they were taught to expect as a result of advertising, special promotions, and promises by the sales group. Marketing processes should be coordinated with production capabilities. Clear expectations should be established before the product is produced or the service is delivered to the customer.

43. Outsource for “Free”
Sometimes it is possible to get suppliers to perform additional functions for the customer with little or no increase in the price to the customer. A task that is a major inconvenience or cost for the customer can be performed inexpensively and efficiently by the supplier. The supplier might be willing to do this task for “free” in order to secure ongoing business with the customer.

44. Optimize level of inspection
What level of inspection is appropriate for a process? All products will eventually receive some type of inspection (possibly by the user). Options for inspection at any given place in the supply chain are: no inspection, 100 percent inspection, or reduction or increases to the current level of inspection. A study of the level of inspection can potentially lead to changes that increase quality of outcomes to the customers and/or decrease costs.

45. Work with Suppliers
Inputs to a process sometimes control the costs and quality of performance of a process. Working with suppliers to use their technical knowledge can often reduce the cost of using their products or services. Suppliers will even have some ideas on how to make changes in a company’s process that will surprise its customers.

F. Manage Time

“Time is money.” This age-old concept provides an opportunity to make time a focal point for improving any organization. An organization can gain a competitive advantage by reducing the time to develop new products, waiting times for services, lead times for orders and deliveries, and cycle times for all functions in the organization. Many organizations have estimated that less than five percent of the time needed to manufacture and deliver a product to a customer is actually dedicated to producing the product. The rest of the time is spent starting up or waiting.

There are five change concepts in this category:

46. Reduce Setup or Startup Time
47. Set up Timing to Use Discounts
48. Optimize Maintenance
49. Extend Specialists’ Time
50. Reduce Wait Time

46. Reduce Setup or Startup Time
Time can be lost and costs increased while getting ready to produce a product or service. Setup times can often be cut in half just by getting organized for the setup. Minimizing setup or startup time allows the organization to maintain lower levels of inventory and get more productivity out of its assets. One approach to reducing setup time incorporates four steps:

1. Define time internal to the setup and time external.
2. Do all of the external work ahead of time.
3. Convert additional internal time to external.
4. Improve the processes affecting the internal time.

47. Set up Timing to Use Discounts
The planning and timing of many activities can be coordinated to take advantage of savings and discounts that are available. Designing a process to take advantage of available discounts can save money and reduce operating costs. An organization must have a system in place to take advantage of such opportunities. For example, taking advantage of available discounts on invoices offered by suppliers for paying bills within ten days of the invoice date requires a system that can process an invoice and cut a check within the discount period. Opportunities to apply this concept require a flexible process and knowledge of the opportunity to take advantage of the timing.

48. Optimize Maintenance
Time is lost and quality often deteriorates when production and service equipment breaks down. A preventive maintenance strategy attempts to keep people and machines in good condition instead of waiting until there is a breakdown. Through proper design and the study of historical data, an efficient maintenance program can be designed to keep equipment in production with a minimum of downtime for maintenance. Learning to observe and listen to equipment before it breaks down is also an important component of any plan to optimize maintenance.

49. Extend Specialists’ Time
Organizations employ specialists who have specific skills or knowledge, but not all of their work duties use these skills or knowledge. Try to remove assignments and job requirements that do not use the specialists’ skills. Find ways to let specialists have a broader impact on the organization, especially when the specialist is a constraint to throughput in the organization.

50. Reduce Wait Time
Nobody likes to wait. Reduction in wait time can lead to improvements in many types of services. Ideas for change that can reduce the time that customers have to wait are especially useful. This applies not only to the time to perform a service for the customer, but the time it takes the customer to use or maintain a product.

G. Manage Variation

Everything varies! But how does knowing this help to develop changes that will lead to improvement? Many quality and cost problems in a process or product are due to variation. The same process that produces 95 percent on-time delivery or good product is the same process that produces the other 5 percent of late deliveries or bad product. Reduction of variation will improve the predictability of outcomes (and may actually exceed customer expectations) and will help to reduce the frequency of poor results. Many procedures and activities are designed to deal with variation in systems. Consideration of Shewhart’s concept of common and special causes opens up opportunities to improve these procedures. By focusing on the variation issues, some ideas for changes can be developed.

Three basic approaches can be taken to deal with variation:

1. Reduce the variation
2. Compensate (deal with the variation)
3. Exploit the variation

This category includes eight change concepts:

51. Standardization (Create a Formal Process)
52. Stop Tampering (Use Statistical Process Control)
53. Develop Operational Definitions
54. Improve Predictions
55. Develop Contingency Plans
56. Sort Product into Grades
57. Desensitize
58. Exploit Variation

The first four concepts deal with ways to reduce the variation. Concepts 55, 56, and 57 provide ways to deal with existing variation. Concept 58 deals explicitly with exploiting variation.

51. Standardization (Create a Formal Process)
The use of standards, or standardization, has a negative and bureaucratic connotation to many people. However, an appropriate amount of standardization can provide a foundation upon which improvement in quality and costs can be built. Standardization is one of the primary methods for reducing variation in a system. The use of standardization, or creating a more formal process, should be considered for the parts of a system that have big effects on the outcomes (that is, the leverage points).

52. Stop Tampering
Tampering is defined as interfering so as to weaken or change for the worse. In many situations, changes are made on the basis of the last result observed or measured. Often these changes actually increase the variation in a process or product. The methods of statistical process control can be used to decide when it is appropriate to make changes based on recent results. Adjustments to a stable process based on the previous result will usually make performance worse, but when special causes are present, adjustments can be useful.

53. Develop Operational Definitions
Reduction of variation can begin with a common understanding of concepts commonly used in the transaction of business. The meaning of a concept is ultimately found in how that concept is applied. Simple concepts such as on-time, clean, noisy, and secure, need operational definitions in order to reduce variation in communications and measurement. An operational definition will usually have two parts: 1) a measurement procedure, and 2) criteria for judgment.

54. Improve Predictions
Plans, forecasts, and budgets are based on predictions. For many situations, predictions are built from the ground up each time a prediction is required, and historical data is not used. The study of variation from past predictions can lead to alternative ways to improve the predictions. There are six basic approaches to develop predictions:

1. Base them on research when results cannot be seen for a long time (for example, school curriculums).
2. Use leading indicators (for example, use housing starts to predict demand for flooring material).
3. Develop time series models to take advantage of autocorrelation in historical data.
4. Make real-time updates of predictions as new information becomes available.
5. Use simple averages of historical data.
6. Anticipate special causes (for example, airlines change cutoffs for loads when a large group books a flight).

55. Develop Contingency Plans
Variation in everyday life often creates problems. Reducing the variation might eventually eliminate the problems, but how do people survive in the meantime? One way is to prepare backup plans, or contingencies, to deal with the unexpected problems. When the variation is due to a special cause that can be identified, then contingency plans can be ready when these special causes of variation occur.

56. Sort Product into Grades
Creative ways can be developed to take advantage of naturally occurring variation in products. Ways of sorting the product or service into different grades can be designed to minimize the variation within a grade and maximizing the variation among grades. The different grades can then be marketed to different customer needs.

57. Desensitize
It is impossible to control some types of variation: between students in a class, among the ways customers try to use a product, in the physical condition of patients who enter the hospital. How can the impact on the outcome (education, function and health) be minimized when this variation is present? It can be done by desensitizing or causing a nonreaction to some stimulus. This change concept focuses on desensitizing the effect of variation rather than reducing the incidence of variation. Examples of this concept include desensitizing the customer to variation in a product or service, desensitizing a process to variation of incoming parts, and desensitizing a product to variation from the perspective of different users.

58. Exploit Variation
It sometimes is not obvious how variation can be reduced or eliminated. Rather than just accepting or “dealing with” the variation, ways can be developed to exploit it. This change concept deals with some ways to turn the negative variation into a positive method to differentiate products or services.
H. Design Systems to Avoid Mistakes

Mistakes (also called errors or slips) occur when actions do not agree with intentions, even though one is capable of carrying out the task. Often a person has to act quickly in a given situation, or he or she is required to accomplish a number of tasks sequentially or even simultaneously. Making slips is part of being human. People might do such things as

- Forget to enter information or enter it incorrectly
- Leave out a step in a process or do them in the wrong sequence
- Include the wrong merchandise in a shipment
- Try to use something in the wrong way
- Put something together incorrectly

Although these mistakes are the result of human actions, they occur because of the interaction of people with a system. Some systems are more prone to mistakes than others. Mistakes can be reduced by redesigning the system to make their occurrence less likely. This type of system design or redesign is called mistake or error proofing.

The frequency of mistakes is a function of the number of opportunities to make mistakes and the probability of making a mistake given the opportunity. For example, if the same information is entered into a computer on three separate occasions, three times more errors would be expected than if the information were only entered once.

Companies should always be looking for ways to reduce the number of steps in a process or the number of parts in a product. This will reduce the opportunity for mistakes. Mistake proofing is then used to reduce the probability of making an error for a given opportunity. Mistake proofing can be done by using technology (such as by adding equipment to automate repetitive tasks), by using methods to make it more difficult to do something wrong, or by integrating these methods with technology. Methods for mistake proofing are not directed at changing people’s behavior, but rather at changing the system to prevent slips. They aim to reduce mistakes from actions that are done almost subconsciously when performing a process or using a product.

One way to mistake proof a system is to make information necessary to perform a task available in the external world and not just in one’s memory. This can be done by writing it down or by actually making it inherent in the product or process. This leads to four important change concepts for mistake proofing:

59. Use Reminders
60. Use Differentiation
61. Use Constraints
62. Use Affordances
59. Use Reminders
Many mistakes are made by forgetting to do something. Reminders are aids for remembering. They can come in many different forms. A reminder can be a written notice or a phone call, a checklist of things to accomplish, an alarm such as on a clock, a standard form, or the documented steps to follow for a process. Reminders are simple to develop, but they are probably the least effective way to mistake proof. Although they do make information available in the external world, reminders can still be overlooked or ignored. For example, a standard process can be defined, but people may have trouble breaking old habits, or they might chose not to refer to the flow diagram or other documentation.

60. Use Differentiation
Mistakes can occur when people are dealing with things that look similar. A person may copy a wrong number or grab a wrong part because of similarity or close proximity to other numbers or parts. Mistakes can also occur when actions are similar. A person may end up in the wrong place or use a piece of equipment in the wrong way because the right directions or procedures are similar to others they might have used in a different situation. For example, a person might drive to work on Sunday morning instead of to the bakery. A person’s mind will at times associate the required object or action with similar but inappropriate ones. Familiarity that results from experience can actually increase the chance of committing mistakes of association. To reduce mistakes, steps should be taken to break patterns. This can be done by, for example, color coding, sizing, using different symbols, or separating similar things.

61. Use Constraints
A constraint restricts the performance of certain actions. A door that blocks passage into an unsafe area is a constraint. Constraints are an important method for mistake proofing because they can limit the actions that result in mistakes. They do not just make information available in the external world, they also make it available within the product or system itself. To be effective, constraints should be visible and easy to understand. Constraints can be built into a process so that accidental stopping or an unwanted action that will result in a mistake can be prevented. Constraints can also be used to make sure that the steps performed in a process or when using a product are accomplished in the correct sequence.

62. Use Affordances
An affordance provides insight, without the need for explanation, into how something should be used. In contrast to a constraint, which limits the actions possible, an affordance provides visual (or other sensory) prompting for the actions that should be performed. Once a person sees the fixtures on a door, he or she should be able to determine whether it opens in, opens out, or slides. There should not be a need to refer to labels or to use a trial-and-error approach. If a process or product can be designed to lead the user to perform the correct actions, fewer mistakes will occur.

I. Focus on the Product or Service
Most of the change concepts in the other categories address the way that a process is performed. However, as the examples of applying the ideas show, many of the concepts also apply to improvements to a product or service. This section contains eight other change concepts that are particularly useful for developing changes to a product or service that do not naturally fit into any of the other groupings.

There are eight change concepts in this grouping:

63. Mass Customize
64. Offer Product/Service Anytime
65. Offer Product/Service Anyplace
66. Emphasize Intangibles
67. Influence or Take Advantage of Fashion Trends
68. Reduce the Number of Component Parts
69. Disguise Defects or Problems
70. Differentiate Product Using Quality Dimensions

Since customers define quality in different ways, concept 63 refers
to customizing products in a cost-effective way to meet various definitions of quality. Concepts 64 and 65 refer to aspects of convenience. Concept 66 refers to the intangible aspects of a product or service. Concept 67 pertains to a particular type of intangible: fashion. Concept 68 is concerned with simplification of a product by reduction of the number of its component parts. Concept 69 discusses changes associated with mitigation of the effects of defects or problems. The last concept uses the dimensions of quality to develop specific changes that will differentiate a product or service.

63. Mass Customize
Most consumers of products and services would agree that quality increases as the product or service is customized to the customer’s unique circumstances. Most consumers would also expect to pay more or wait longer for these customized offerings than for a mass-produced version. To mass customize means combining the uniqueness of customized products with the efficiency of mass production.

New technology may contribute to the ability to mass customize-genetically engineered drugs would be an example. Another method of mass customization is differentiation of the product or service at the last moment, perhaps even by the customer himself. Learning to design and use modules is another way to apply this concept. Mass customization can be done after building knowledge to predict the most likely choices of customers or to understand the causes of desired outcomes. For example, knowledge of which fertilizer will work best under different conditions can lead to a product customized for particular customers.

64. Offer the Product or Service Anytime
Many products and services are available only at certain times. The movie will be shown at 7:00 p.m. and 9:30 p.m. The Motor Vehicle Bureau is open from 9:00 a.m. to 5:00 p.m. The doctor’s office hours are 1:00 p.m. to 5:00 p.m. Monday through Friday. The bank is open from 9:00 a.m. to 3:00 p.m. Your new car will be available in two weeks. These constraints almost always detract from the quality of the product or service. How can these constraints be removed? In some cases a technology breakthrough such as the ATM is needed. In other cases, prediction plays an important role-for example, predicting what type of cars customers will order. However, in many situations the constraint is created because it is more convenient for the provider of the service than for the customer. Would most people prefer the bank to be opened from 9 a.m. to 3 p.m. or from 3 p.m. to 9 p.m.? Offering the product or service anytime is different from just reducing wait time. To achieve this goal often takes a totally new conceptualization of the product or service. For this reason, “anytime” is an important concept for expanding the expectations of customers.

65. Offer the Product or Service Anyplace
An important dimension of quality for most products and services is convenience. To make a product or service more convenient, free it from the constraints of space. Make it available anyplace. For products, the constraint of space is often related to the size of the product. Making a product smaller or lighter without adversely affecting any of its other attributes almost always improves the quality of the product. One of the most striking examples is the miniaturization of the computer to the point that it can now be carried in a briefcase and used virtually anyplace.

Miniaturization is often the result of technology breakthroughs. However, technology is not the only means by which to obtain “anyplace” attributes. A product or service that the customer must obtain by coming to the provider’s facility can be made available in the customer’s space, and thus expand the customer’s expectations.

66. Emphasize Intangibles
The tangible aspects of a product or service are those aspects that can be readily perceived, especially by the sense of touch. Tangible aspects are associated with mass or matter-for example, the shape of the table or the roominess of the interior of the airplane. Although services have matter associated with them, such as equipment, services are usually less tangible than products.

Opportunities for improvement can be found by embellishing the product with intangible aspects. Three ways to accomplish this are by miniaturizing, by providing information (electronically or otherwise), and by developing producer-customer relationships. For mature products, this may be the primary way to change customer expectations. For many years the tangible aspects of computers, such as their size, were the focus of improvements in quality. Today, clones of all types are available at low prices. The intangible aspects of the software that runs on the computers have become more important.

67. Influence or Take Advantage of Fashion Trends
The word “fashion” evokes images of French dress designers presenting their new collections of expensive women’s clothes in Paris. However, for many products such as everyday clothes, automobiles, furniture, dishes, and floor coverings, quality is defined as much by aesthetics as by utility. Often the utility of the product is assumed and the aesthetics are what change the expectations of customers.

Trends in public opinion have an aspect of fashion to them and as such are also a source of ideas for new or redesigned products. Health, safety, or security concerns may dominate public discourse. The economic environment will influence whether people prefer luxury or frugality in the products they buy.

68. Reduce the Number of Components
Reducing handoffs was one of the change concepts for simplifying a process. Similarly, reducing the number of component parts is a way to simplify a product. Benefits accrue to the manufacturer, to the customer, and to those who repair or maintain the product. Components in this context can mean component parts, ingredients, or multiple types of the same component.

Reduction in the number of components can be achieved in different ways. One way is through design of the product so that one component performs the functions previously performed by more than one. Another method is to standardize the size, shape, or brand of similar components. A third method is to package components into modules.

69. Disguise Defects and Problems
“Buy the darker color; it will hide the dirt.” One can easily imagine this bit of advice being provided to a couple with two young children who are purchasing a rug for their living room. The darker color will hide the defect (the dirt), although it will not remove it. The couple could try to remove the defect by not allowing the children in the living room, but this change would cause more problems than it would solve.

The basic idea behind this change concept is that in some instances, especially in the short term, it may be better to hide the defect in a product or service than to remove it. However, the longer-term strategy is to remove the defect. Also included in this category are actions taken to make the defect more palatable to the customer. This change concept does not include false advertising, in which claims about the product are made that are not true. Also excluded are defects that are hidden at the time of sale only to emerge in later use of the product.


70. Differentiate Product Using Quality Dimensions
Quality is improved as the match between products and services and the needs they are designed to satisfy is improved. The degree of matching is determined using the definition of quality. Customer research can provide an understanding of how customers define quality and how this definition differs among different groups of customers. The dimensions of quality provide a model to help categorize various measures of quality. The measures of quality for a specific product do not have to contain all of the dimensions. Two completely different products can be considered “high quality” because different dimensions of quality are considered important for the two products. To compete on quality, an organization must determine what dimensions are important to the group of customers (segment of the market) on which the organization is focusing.
