Establish Process Performance Baselines
The organization's process performance baselines are a measurement
of performance for the organization's set of standard processes at
various levels of detail, as appropriate. The processes include:
- Individual process elements (e.g., test-case inspection element)
- Sequence of connected processes
- Processes that cover the entire life of the project
- Processes for developing individual work products
There may be several process performance baselines to characterize
performance for subgroups of the organization. Examples of criteria used to categorize subgroups include:
- Product line
- Application domain
- Complexity
- Team size
- Work product size
- Process elements from the set of standard processes
Allowable tailoring of the set of standard processes may
significantly affect the comparability of the data for inclusion in process
performance baselines. The effects of tailoring should be considered in
establishing baselines.
- Collect measurements from the undertaken projects.
The process in use when the measurement was taken is recorded to enable
appropriate use at a later date.
- Establish and maintain the organization's process performance
baselines from the collected measurements and analyses. Process performance baselines are derived by analyzing the collected measures
to establish a distribution and range of results that characterize the expected
performance for selected processes when used on any individual project in the
organization. The measurements from stable processes from projects should be used; other
data may not be reliable.
- Review and get agreement with relevant stakeholders about the
organization's process performance baselines.
- Make the process performance information available
across the organization in the measurement
repository. The process performance baselines are used by the projects to
estimate the natural bounds for process performance.
- Compare the process performance baselines to the
associated objectives.
- Revise the organization's process performance baselines as
necessary.
