Last month, this column addressed the need for (and philosophy behind) sample testing certain systems when 100% functional performance testing (FPT) is impractical from a time and/or budget perspective.
In this column, I will describe the “issue” disclosed through analysis of the trend graph included in my January 2012 column. I will also introduce a new system and show its trend graph, leaving it up to the reader to discover the operational “issue” illustrated in the graph. The answer will be given at the start of next month’s column.
