Chapter 33. Comparison of Production Metrics
“Measure the smallest thing you can measure. . . Because it gives you fast feedback.”
The manageability of a software development process can be compared and predicted through a study of the available management metrics for Throughput. Shewhart's work on Statistical Process Control and Wheeler's classification of the states of control provide some clues. Essentially, the output from the process—the pieces of client-valued functionality being delivered in the system—must be measured. The variance in the system must also be measured against a set band of acceptability. The smaller the unit of measurement in comparison to the size of the output, the more feedback is being provided. The more ...
