Basic Elements of Continuous Process Improvement

Alexander defines a pattern as describing “a problem which occurs over and over again in our environment and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice”[1]. Here, the emphasis is put on the fact that a pattern describes a recurrent problem and it is defined with its associate core solution. According to Alexander, what repeats itself is a fabric of relationships. For example, when a statistical consultant is first approached by a customer and gets a first look at some data, or a detailed description of it, the statistical consultant is initiating a basic investigation to understand the context of the problem. This example represents a structural pattern that is repeatable in many different settings—for example, in a troubleshooting assignment in manufacturing, or a market research study. Aligned with this structural pattern, there is a pattern of events that is also repeatable; in our example, the basic investigation preceding the statistical analysis takes place time and time again within a company. It is important to note that a pattern relates a problem to a solution.

At the stage of confirming the content validity of the questionnaire, the questions with CVR < 0.62 were deleted and the questions with CVI < 0.7 were reviewed through a focus group of occupational health professors of the School of Public Health, occupational medicine specialists, a statistical consultant and occupational health experts. Finally, 24 items in the range 1 = strongly disagree to 10 = strongly agree were approved. The value of the S-CVI index (mean CVI of all the questions) was obtained at 0.71 (see Table 2) (Figure 1).
