A process performance baseline (PPB) documents the historical results achieved by
following a process. A PPB is used as a benchmark for comparing actual process
performance against expected process performance. A process performance model
(PPM) describes the relationships among attributes (for example, defects) of a process
and its work products. A PPM is used to estimate or predict a critical value that
cannot be measured until later in the project??™s life??”for example, predicting the
number of delivered defects throughout the life cycle. More information on PPBs
and PPMs can be found in Chapter 19, ???A High Maturity Perspective.???
Remember, don??™t wait until Level 4 to focus on measurements and to start collecting
measures??”that??™s way too late. The Measurement and Analysis process area
resides at Level 2, so if you are attempting to achieve a Level 2 maturity level rating,
this is probably not a process area to tailor out. And if you are using the continuous
representation, which supposedly allows you to select which process areas to use,
Measurement and Analysis should also be selected.
