With the rapid spread of the quality movement, many people spend a lot of time and energy implementing quality management in their own enterprises. However, they are often disappointed to find that it is difficult for them to know which quality tools and techniques are best for which specific situations. high precision cheap price Professional OEM Custom precision edm
Here are a few quality tools and how to use them to solve everyday business problems. A discussion of each tool includes the following: when to use it, when not to use it, training, what it can serve, precautions, and procedures for use.
— 1 — Fishbowl meeting
It’s a way of organizing meetings. Different groups come together to share their views and information in a spirit of cooperation. So, having sales meet with customer service, or upper management with management consultants, certainly works.
When to use it: Fishbowl meetings enable certain groups to communicate with other stakeholder groups such as customers, suppliers, and managers.
When not to use it: This approach should not be used if the responsibilities of each group cannot be clearly identified.
Training: Meeting facilitators need to be trained. high precision cheap price Professional OEM Custom precision edm
What can be achieved: Rapidly increase understanding and eliminate misunderstandings.
Caveats: These meetings have huge implications. May give away and make insiders and bystanders feel threatened, so careful organization is required.
Procedure to use: Arrange attendees in two circles, inner and outer. People in the inner circle are more active in meetings, while those in the outer circle observe, listen, and provide information when necessary. At the end of the meeting, the improvement plan is recommended and approved by the people in the outer circle.
—2—Lateral Thinking
It’s a tool for finding new solutions to old problems.
When to use: Use when you need to find new methods and ideas because the old methods and ideas no longer work or are not good enough.
When not to use it: Don’t use it when constraints prevent this new way of thinking from working. high precision cheap price Professional OEM Custom precision edm
Training: Lateral Thinking for Management by Edward de Bono is recommended (Penguin 1982).
What can be achieved: To develop new ideas, stimulate creativity, and find feasible solutions.
Matters needing attention: Traditional logical thinking is required to support it. Edwards suggests that only 10% of the problem-solving process involves lateral thinking.
Using the procedure: Identify the problem. Use humor, random permutations, and challenges to popular beliefs to develop lateral thinking solutions. Appropriate refinement and selection of various ideas found.
For example, when the traditional market for a manufacturer of industrial sewing reels disappeared, the company had to find another outlet. In this regard, the instinctive reaction of company managers is to start from conventional thinking and find new outlets, new markets or new sales methods for products. However, developments soon showed that they needed a radical solution.
The company held a brainstorming session that put no boxes on the participants. Ideas should draw on existing skills and experience, but only as a starting point. As a result, lateral thinking led them to golf balls and they became a successful golf ball manufacturer. high precision cheap price Professional OEM Custom precision edm
—3—Pareto Analysis (Pareto Analysis)
This approach emphasizes finding the critical few causes for 80% of problems (typically 20%).
When to use: Use this method whenever a problem has multiple variables and you need to identify the most critical one. Especially useful at the beginning of an improvement project.
When not to: There is no need to use this method if you have a more sophisticated system setup.
Training: Basic statistical knowledge is required for analysis.
What Can Be Achieved: Very intuitive demonstration of how to prioritize issues and where to focus resources for best results. This display allows all levels of the enterprise to understand at a glance.
Caveats: It is always important to analyze the results carefully; not only rely on the data but also use common sense to identify the causes and priorities of problems. high precision cheap price Professional OEM Custom precision edm
Use procedures: to identify problems and possible causes. Gather information about the cause. Draw a Pareto analysis diagram, the abscissa indicates the cause, and the ordinate indicates the problem, expressed in terms of occurrence, frequency, or cost. Find out the most critical reasons. Use improved techniques to eliminate the causes of problems in order of importance.
For example, a washing machine manufacturer has a quality crisis. In an extensive credibility test, a major magazine ranked its product last and advised consumers not to buy it.
The company has a well-documented error record, listing 22 types of errors. But using Pareto analysis, just 4 of these errors accounted for 83% of all records.
—4—Quality Function Distribution Diagram (QFD)
It is a product and process design tool that can be used to translate the voice of the customer into product or process characteristics. Taking this approach prevents companies from implementing ideas just because they seem to work.
When to use it: To design or redesign a product or process to ensure that it provides the features customers actually want; designed for manufacturing, but can also be used in service industries.
When not to use it: Do not use this approach if the issues are well-prioritized, the process design is effective, or the design team is experienced.
Training: The method uses specific conventions, associated matrices and scoring criteria. There is a need for training in this regard. high precision cheap price Professional OEM Custom precision edm
What it can achieve: The ability to distinguish between basic and desired product and process characteristics, so that it is possible to see where costly technology or engineering investments will pay off. It also provides a framework for assessing the impact of product or process changes.
Do’s and Don’ts: Take the time to do market research to find out what your customers really want.
Procedures used: Research customer needs. Identify process design features that meet customer needs. Create a matrix that compares customer needs with design features (ie performance/solution matrix) and scores them. Select about 5 design features with the highest scores, and then build a matrix diagram according to 3 levels: design features and key component characteristics, key component characteristics and manufacturing processes, manufacturing processes and production requirements.
For example, a lawn mower manufacturer spent time and money redesigning the controls on its best-selling lawn mowers, only to find that customers were unresponsive. Therefore, when a company manager plans to improve another older model, he wants to make sure that the improvement is really what the customer wants. high precision cheap price Professional OEM Custom precision edm
The findings show that customers are interested in performance. Improving the efficiency of the motor, drive chain, and knife can therefore have a much greater impact than improving control performance.
—5—Association Tree Diagram
This graphical tool provides a hierarchical classification of related items. This is a great thinking tool because it provides a quick way to generalize ideas and add detail as related branches emerge.
When to use: Use this diagram to explore many different ways to achieve the same goal.
When not to use: Not for detailed comparisons of options. It is only used to explore new directions in general.
Training: No formal training is required, but having a coordinator is helpful.
What can be achieved: The diagram logically reveals what methods should be used to achieve the goals, what actions and resources they require.
Caveat: Be prepared to fall back on the association tree diagram if the method you choose doesn’t hold up to analysis. high precision cheap price Professional OEM Custom precision edm
For example, a small growing company used this approach to consider employee childcare. Many employees joined the company right out of college and are now supporting their children.
The company meets to discuss options. As a result, everyone was in favor of building a day care center. But the tree diagram shows that the potential cost is too high and the local regulatory requirements to meet are too many to implement. So the company opted for a childcare subsidy program to give employees with children a choice.
—6—solution effect analysis
This type of graph is used to analyze the possible effects of the solution at hand.
When to use: Use this method when proposing change. It allows you to see the effect of each solution.
When not to use it: If what you are proposing is not a fundamental change, don’t use it.
Training: No formal training is required, but assistance is useful.
What can be achieved: A way of thinking that looks forward and anticipates the impact of the proposed solution, avoiding unforeseen effects.
Caveat: Don’t hold back people when they see little promise for the change you’re working on. They didn’t mean to be hostile, and maybe they were right. Counseling can reduce your feelings of intimidation.
Procedures in use: Write down the solution you are considering implementing and place it on the left side of the diagram, with the arrow pointing to the right. Significant effects are marked with sub-arrows on either side of the main arrow. Brainstorm all possible effects and add them to the diagram. Plan and implement actions to ensure the program is effective.
For example, a company decides to introduce flexible working hours to reduce the time employees lose on their commute while making the most of resources. As the deadline for switching to the new hours approached, the HR department coordinating the change became concerned that employees hadn’t figured out what the new hours meant. To this end, the company held a series of program effect analysis meetings, so that the company’s employees can think through various problems, so as to make better preparations for the adoption of new working hours. high precision cheap price Professional OEM Custom precision edm
