Using SQCpack 2000 to answer everyone's questions?

One person's data is another person's question. What do you do when everyone wants something different from the data? SQCpack 2000 can respond to everyone. Patiently.
If, for example, a company uses Pareto charts to track defects in order to discover the greatest sources for these defects, these charts will communicate the required information visually by creating Pareto charts from entered data. In order to understand the issue more fully, however, someone might ask whether the defect rate is increasing or decreasing over time. Another asks for the data as percent-of-output rather than in raw numbers. And someone else may not need to know the defect percentage, but wants instead to know what the yield is.
While SQCpack 2000 may not be all things to all people, it will respond to all of these needs effortlessly, providing a variety of charts that give visual information based on the same set of data. It is helpful if a user anticipates the demands that will be made on SQCpack for chart representation, and enters the necessary characteristic to generate that chart.  In this case, what is required is that the user enter a characteristic for units produced (for percent of defects) and a computed characteristic that uses the two columns to calculate a yield (total defects divided by the total production times 100).
Watch for new features like chart annotation, CUSUM, and new statistical chart titles in the next release of SQCpack 2000, in beta test stage now.
