Most corporations/companies use quality tools for many functions associated with controlling and maintaining the quality of their products. Although a great number of quality tools are available for some domains, fields and practices, an company may use many quality tools across such domains.

These quality tools are pretty common and apply to any condition. They can offer lots of data about problems in the corporation supporting to derive solutions for the same. Short training (self-training) is enough for an company to start the use of the tools.

Thus, the use of quality tools must be a fundamental practice in the corporation to enhance efficiency. Organizational orientation programs must include training on these tools so that all the workforce taking part get to learn about these fundamental quality tools.

Let’s learn about some of the quality tools here.

Quality tool 1 - A3 REPORT #

An A3 Report is a helpful tool for problem-solving and continuous improvement for any business. The A3 Report format allows the recognition, clarity, evaluation and settlement of all issues that you can record on a single sheet of A3 size paper.

is from the European standard paper size of 11" by 17." The A3 report focuses on the Plan, Do, Check, Act (PDCA) method. It incorporates the basic premise for problem-solving and continuous improvement.

The A3 report is an effective way of communicating. It is a valuable problem-solving and analytical thinking tool to drive continual improvement. It is an invaluable tool for managers and supervisors to share solution techniques with their team members. The A3 report or way of thinking is a valuable tool for integrating a problem-solving culture across the company.

How to Implement A3 Problem Solving method?** An A3 report comprises several steps following the PDCA structure of the Plan, Do, Check, and Act. The A3 Report may use different forms based on the company’s needs and preferences. The following paragraphs offer details on the simple steps and some tools used to put in place the A3. One point all forms seem to have in common is that they follow the PDCA solution process. The following are typical steps and where they fall into the PDCA structure: Plan/Planning: 1 - Define the issue: ? The first step is to determine the problem or to recognize the need for betterment. Describe the optimal situation, the working standard, or the required situation. Describe the current position or scenario. How is the present state distinct from the ideal state or working standard? State your objectives and describe how the company would gain from performing the A3 and closing the gap. What will be the value realization by completing the A3 exercise?

2 - Containment*** In some A3 formats, you use a segment for immediate containment acts. The aim of containment is to protect further problems from happening. Or, the aim is can be to cause adverse effects on other procedures, goods or departments.

3 - Breaking down the problem*** Next, the team should either break or further describe the problem. This you can do by requesting any appropriate 5W (What, When, Where, Who, Why) and 2H (How, How many, How often) questionnaires. Give priority to issues and recognize the point of incidence or escape.

4 - Defining objectives/Mission/Goal*** The A3 team should set targets for the desired progress. The objectives should be specific, measurable, achievable, realistic, and timely (SMART).

5 - Examine the Root Cause*** The team should analyze the root cause using different quality tools. They can involve but not restrict themselves to the data analysis. Must complete the Cause and Effect diagram or Ishikawa diagram followed by the 5 Why exercise.

6 - Countermeasures*** The root cause assessment must then list countermeasures or correctional acts. Specify the countermeasures that are achievable and have a due date by the responsible individual.

Do:** 7 - Deployment/setup Implementing the remedial steps should include teammates, time and money required to complete each task. You may need help from external resources or test facilities sometimes. Some countermeasures may need repairing or replacing tools or other capital expenses. Throughout the entire process, keep the relevant management levels updated.

Check:** 8 - Surveillance and validation The A3 team should verify many countermeasures and quality controls. These may include SPC (Statistical Process Control) data, process or product audits and customer reviews.

Act:** 9 - Optimize and enhance During this phase of A3, the team should take steps to optimize new processes. The team should upgrade all normal activities and work specifications. Do a quick exercise on the things going right and wrong (TGR/TGW). Record what was successful and what change would be useful in the A3 report.

Quality tool 2 - Affinity Diagram #

What is an Affinity Diagram?** An affinity diagram method separates the thoughts, realities, methods, confusing matters, or issues into their normal relativity. Jiro Kawatika first developed it in 1960, so we call it the KJ diagram. (Also called Affinity table, Affinity mapping, or thematic analysis). companies use the Affinity diagram when there is a complicated problem to solve. They do this by gathering the information about the problem to their likeness or affinity. This resolves many concerns and issues when we do not know how to begin, what to begin, or where to begin. The analysts use the Affinity diagram, particularly when a group is brainstorming and there are many problems to resolve. We call the combinations of like kinds Affinity Sets. We use these Affinity Sets to resolve the issues. Hence, we use the Affinity diagram in normal and important issue resolution strategies.

When should you use an Affinity diagram? #

When you are facing many realities and views in superficial confusion. When problems appear enormous and complicated — When team agreement is essential.

After we have completed a brainstorming procedure. When assessing spoken information, such as inspection results. When you are accumulating and arranging exclusive sets of information. When you are creating connections or subjects between ideas. When lessening qualities to classifications that the next level can take care of.

How do you create an Affinity diagram?** Step-by-step procedure to create an Affinity diagram.

The first step is to place the recorded ideas, realities, problems, or concerns and paste them on the board. Write the notes on the sticky notes, after which you can paste them on the board where everyone can see and understand. When the suggestions are available from everybody, take another sticky note and test whether it can make the header of the team. Likewise, test some other suggestion and test whether it correlates to any team. Keep using the sticky note for each suggestion and keep checking every team by team to which it belongs. By now you may have accumulated some groups or teams under each team. Now, make them perfect by re-examining them. Discover the subject of every team as you perfect them and create a data form out of it. Grade the teams based on their significance by which one grades first, second, and so on. It is more convenient to link the articles of every team by line diagram to some other article of some other team to understand more about them. Explain what you have grouped like issues, concerns, realities, views, pain spots, and so on and analyze the line-up of the teams. Now pay more attention to deciphering out what you have systematized rather than recognizing the likeness or similarity.
