[The following article appears in _The_Public_Sector_Network_ News_, Winter 1995 edition, pages 5, 7, 8, and 9. Note: the technique described here is very similar to that used by Florida Power and Light in its story boards. At FPL, the Q. C. story is told on a large board tht each team maintains.] DOCUMENTING IMPROVEMENTS USING A Q.C. STORY What is a Q.C. Story? A Q.C. Story is a document that is used to explain work done during an improvement effort. It contains elements that explain the steps in the improvement effort. This standard format makes it easy to understand the details of an improvement project. The Q.C. Story is intended to be written during a project to help the effort remain on track, making regular progress. The Q.C. Story consists of the following eight elements: O The ISSUE section explains the Issue Statement for the project. O WHY SELECTED explains why this issue was selected, how it was selected, and how the issue relates to customer satisfaction. O INITIAL STATUS explains what was initially known about the issue when we first started to work to improve it. O ANALYSIS OF CAUSES explains what causes have been identified and how we performed the analysis to find the causes. O PLANS quantifies the improvement objective, delineates possible solutions and how each was evaluated, and explains the selected solution(s)and plans for implementation . O RESULTS compares the actual results achieved with the target in the objective statement. O STANDARDIZATION explains what was done to hold the gains achieved through the improvements to the process. O And FUTURE PLANS explains what possible issues could be worked on next and which of those issues has been selected for the next improvement effort. A detailed description of each of the eight elements of the Q.C. Story is provided. Also, there is a checklist of questions you can use to help you write an excellent Q.C. Story. Issue This section of the Q.C. Story contains one simple sentence, the Issue Statement. An Issue Statement contains three elements: O Direction O Measure O Reference to a process, product, or service For example: "Reduce (direction) the percentage of contracts that are returned for rewrite (measure) in the XYZ Contract Department (reference)." An Issue Statement is simply a description of the measure and the way in which the measure will change. It does not contain a goal, just the direction of change. Until further analysis can be done to find the causes of the issue, it is impossible to determine a meaningful goal for the measure; therefore, a statement like: "Reduce the percentage of contracts that are returned for rewrite by 50%" is not a valid Issue Statement. We may want a 50% improvement, but we must let the analysis tell us what is possible. Be careful of words like "improve" and "lack of." Statements such as "improve customer satisfaction" or "lack of training" are not issue statements because they contain no direction, measure, or reference. We could say "improve customer satisfaction with the quality of contracts" if we had a method to measure customer satisfaction with contracts. The term "lack of" is really a cause in disguise, not an issue. If "lack of training" was to be accepted as an Issue Statement, the obvious solution would be to "do training." It would require no analysis to find the cause because the cause is implied from the beginning. Another word to avoid in an Issue Statement is "and." Usually when "and" is in the Issue Statement, it indicates the presence of two issues. It is commendable to try to resolve two issues at once, but it can be very difficult and is sometimes impossible. If the two issues have the same set of causes, then choosing one issue will automatically lead to the resolution of the second. If the two issues have different causes, it is a mistake to try to analyze and solve them together. In either case, they should be two separate stories. Why Selected In this section we explain why we are working on this issue. It is easy to say "customer satisfaction." The question that needs to be addressed here is "how do we know that this is the most important thing to work on" to improve customer satisfaction? We need to show how we know this is an issue. Is the knowledge of this issue gained through surveys, customer feedback, or complaints? How many complaints! There should be a clear relationship to the customer and the customer's needs. We should explain how the problem is affecting the customer and how solving it will benefit the customer. This is also the part of the Q.C. Story where we explain HOW selected. Certainly, there are many issues that might be addressed. What was the method used for the selection of the most important issue? It is possible that this issue was selected because it is part of a higher-level manager's improvement plan. We should be able to show how this issue fits with the higher-level plans. Initial Status Here is where we explain the status of the issue before we started working to improve it. Several things need to be explained for the reader to understand the Initial Status. The most important thing to show in this section of the Q.C. Story is the status of the measure in the issue statement. If the measure was "% of rejected contracts," then we would need to explain what the percentage was in the months before we first started working on the issue. If the measure was "cycle time to get signature approval," then we would show what the cycle time was. Just giving one data point is less valuable than showing the status of the measure through time. Knowing that last month the percentage of rejected contracts was 16% is of some value, but showing the percentage of rejected contracts each month for the past year gives a better picture of the status of the measure. This is a good place to use graphical tools like line graphs or control charts. If there are other facts or diagrams that would help us to better understand the Initial Status, they can be included in this section of the story. A flowchart of the initial process is very helpful. We might explain how many people were involved, the number of shifts, the floor space requirements of the process, related measures that might be affected, or previous attempts to solve the problem. Any of these could be included in this section of the story if they helped the reader to understand the situation before the issue was improved. Analysis of Causes The reason for performing analysis is to find the cause(s) of the issue. Thus, we explain the cause and provide the data that were used to find and verify the cause. Usually the first level of analysis is demonstrated through a pareto diagram. This diagram shows the various aspects of the problem and shows which is the most frequent or common. It is easy to make the mistake of thinking that a pareto diagram provides true analysis of causes. This is usually not the case. Most often, the pareto diagram categorizes types of problems or defects, but this is not a description of cause. It is helpful to know the most frequent type of problem, because this should be the target of further investigation. Next, we may use an Ishikawa (fishbone) diagram to theorize the causes of the most common problem (from the pareto). Failure mode and effects analysis (FMEA) is another excellent tool for theorizing causes. Data are collected to determine and verify which of the several possible causes is, in fact, the cause of the problem. There are several analytical tools to help with this effort: checksheets, histograms, or scattergrams are very useful. The story should include the time period over which the data were collected. We sometimes run small-scale experiments to collect data about causes or to verify that we have found the actual causes. When the results from these experiments show that our theories are correct, we can include them in this section of the story. How causes are verified is an important but commonly overlooked part of the story. This section of the Q.C. Story concludes with a statement of "Necessary Action." This is not a plan; it is a statement that summarizes what needs to be done to eradicate the cause. Plans This section explains the Objective Statement, the possible solutions, the method that was used to evaluate the possible solutions and select the best solution(s), and the details of the plan to implement the solutions. A complete Objective Statement contains: O Direction O Measure O Reference O Target (or goal) O Time Frame O Owner For example: "Reduce (direction) the percentage of contracts returned for rewrite (measure) in the XYZ contract department (reference) by 65% (target) by the end of the fiscal year (time frame). Owner: Joe Jones." It should be clear that the target in the Objective Statement is derived from the analysis. For example, let's say our issue was "percentage of contracts returned for rewrite" and that the Initial Status of the measure was 25% of the contracts returned. If our analysis showed that half of the problem contracts were returned because they did not contain a needed financial figure and we felt we could remedy this cause, then we could set a target reducing the percentage of rejected contracts by 50%. (We could also say reduce the percentage of returned contracts from 25% to 12.5%.) The Q.C. Story should be written in such a way that it is easy to see how the analysis, the plan, and the target are related. The details of the plan should be aimed at eradicating the cause, and if the cause is eradicated, the measure should change to a predictable level. There should be some indication of the different solutions that were considered. There also should be some information about how the different alternative solutions were evaluated and how the final solutions were selected. Details of the plan could include planning sheets or tables, PERT or GANTT charts, timelines, and review tables to describe how the planned implementation proceeded. The reader should be able to tell if the plan was implemented on schedule. Results In this section, we compare the actual results from the improvement effort with the target in the Objective Statement (the expected results). This comparison should be shown in the same format as the information in Initial Status and Analysis. If the Initial Status was shown in a control chart, then the Results should be shown in the same type of control chart. If an important part of the Analysis was shown in a pareto diagram, then some of the Results should show a comparison with that pareto diagram. The reader should be able to tell if the expected results were achieved within the original time frame described in the Objective Statement. If there is a deviation between the expected results and the actual results, some additional analysis should be provided in this section of the story to explain the cause of the gap between the two. This is also where we explain any other results (in addition to the changes in the measure) that occurred as a result of implementing the plan. These could be positive benefits or they might be negative side effects. If we were working on an issue of percentage of contracts to be rewritten and as a result of our improvement efforts morale went up, we would want to include that information in the story. Conversely, if we saw a new kind of problem get introduced in the process of writing contracts, that information should be included also. Standardization Here we explain the steps that were taken to ensure that the implemented solution will remain in effect. We want to prevent the process from reverting to its previous state so we can continue to hold the gains achieved through the process improvement. Standardization involves six types of activities: 1. Documentation-the new process will need to be documented by changing procedures, material checklists, etc. 2. Training in the new process-people will need to learn the correct way to do the new process. 3. Training in the skills needed to perform the new process-- besides to learning the steps in the new process, people may need to learn additional skills, such as how to run a new computer program or how to use a new piece of equipment. 4. Physical reorganization-repositioning desks, shelving, equipment, machinery, etc., has the effect of preventing the process from reverting to its original state and helps hold the gains of the improvement. 5. Sharing--we can increase the benefits of improving a process if we share what we learned with others who might benefit from our experiences. 6. Monitoring--by tracking the improved process metrics regularly, we can be assured that the process will continue to run at the improved level and we will quickly be able to note any deviations. It is helpful to assign a specific custodian to be responsible for monitoring. Although Standardization takes these several forms, doing one or two is not sufficient to ensure that the process is standardized. Most or all of the actions are necessary to ensure that we can hold the gains It is not necessary to include the document and training materials in the Q.C. Story, just a description of the actions taken to Standardize. Future Plans In this last section we list the problems that could be addressed next and the issue that has been selected to be the next project. First, there should be a list of possible problems that could be selected as the next project. This could include problems directly related to the issue that has just been improved. It is possible that one (or several) aspects of an issue have been resolved, yet still more need to be improved. On the other hand, the list of issues could include problems unrelated to the issue in the current Q.C. Story. For example, if the issue in the current story was "reduce the percentage of contracts returned for rewrite," we could have made significant gains in reducing the percentage, but more work could still be done. On the other hand, customers might be satisfied with the progress to date and some other issue may have become more urgent than the current issue. We conclude this section with the identification of the issue (from the list) that will be the next issue for improvement. This identification creates a connection between the current improvement effort and the next project. Q.C. STORY QUICK REFERENCE You should be able to answer "yes" to each question.
