At Yokogawa-Hewlett-Packard in Japan, the QC story is told using a flip chart of size 6 x 6 feet (2 x 2 meters). The project team uses colored markers to show the PDSA cycle (Shewhart cycle) and the SDSA cycle (Standardize, Do, Study, Act). After each manager writes an interpretation of the policy statement, the interpretation is discussed with the next manager above to reconcile differences in understanding and direction. In this way, they develop a consensus.
When the management attempts to make a managerial diagnosis, it is important that the people whose work is being diagnosed be properly prepared to enter the discussion. For this purpose, it is very helpful if everyone knows how to tell the QC story. Telling the story properly requires seven steps.
1. Problem definition: This step includes an explanation of why the problem is important (which will tie it to the priority statements of the top management or to a problem that is essential as seen at the lower levels). Normally, this step includes a discussion of the losses that occur because of the problem. The team will make an estimate of what should be done and work on it. A target is often specified, though it is understood that reaching such a target cannot be guaranteed. A schedule is proposed.
2. Data collection: This step involves observing the time, place, type, and symptoms of the problem. It involves data gathering and displays an attempt to understand the important aspects of the problem.
3. Analysis: In this step, various tools for quality analysis are used. This includes Control charts, Pareto charts, cause-and-effect diagrams, scatter diagrams, and histograms.
4. Action: Based on the analysis, an action is taken.
5. Study: The results are studied to see if they conform to what was expected and to learn from what was not expected. Data is taken to confirm the action.
6. Act or standardize: Appropriate steps are taken to ensure that the gains are secured. New standard procedures are introduced.
7. Plans for the future/Continuity: As a result of solving this problem, other problems will have been identified and other opportunities recognized.
These seven steps do not describe how a problem is solved. Problem-solving requires iteration, and it is often necessary to go back to a previous step as new data is found and better analysis is made. However, when the time comes to report on what was done, the above format provides the basis for telling the story in a way that makes it comprehensible to the upper levels of management.

It is believed to have been first developed by a Japanese tractor company, Komatsu.
Quality storyboards were also used by Florida Power & Light as part of their quality drive during the 1980s to win the Deming Prize.
