The common measures for the organization are composed of process and product measures that can be used to summarize the actual performance of processes in individual projects in the organization. The organizational data for these measures are analyzed to establish a distribution and range of results, which characterize the expected performance of the process when used on any individual project in the organization.
In this process area, the phrase “quality and process-performance objectives” covers objectives and requirements for product quality, service quality, and process performance. As indicated above, the term “process performance” includes product quality; however, to emphasize the importance of product quality, the phrase “quality and process performance objectives” is used rather than just “process-performance objectives.”
The expected process performance can be used in establishing the project’s quality and process-performance objectives and can be used as a baseline against which actual project performance can be compared. This information is used to quantitatively manage the project. Each quantitatively managed project, in turn, provides actual performance results that become a part of the baseline data for the organizational process assets.
The associated process performance models are used to represent past and current process performance and to predict future results of the process. For example, the latent defects in the delivered product can be predicted using measurements of defects identified during the product verification activities.
When the organization has measures, data, and analytic techniques for critical process and product characteristics, it is able to do:
