Establish and maintain the process-performance models for the organization’s set of standard processes.
Process-performance models are used to estimate or predict the value of a process-performance measure from the values of other process, product, and service measurements. These process-performance models typically use process and
product measurements collected throughout the life of the project to estimate progress toward achieving objectives that cannot be measured until later in the project’s life.
The process-performance models are used as follows:
· The organization uses them for estimating, analyzing, and predicting the process performance associated with the processes in the organization’s set of standard processes.
· The organization uses them to assess the (potential) return on investment for process improvement activities.
· Projects use them for estimating, analyzing, and predicting the process performance for their defined processes.
· Projects use them for selecting processes or subprocesses for use.
These measures and models are defined to provide insight into, and to provide the ability to predict, critical process and product characteristics that are relevant to business value.
Examples of areas of concern to projects in which models may be useful include the following:
· Schedule and cost
· Reliability
· Defect identification and removal rates
· Defect removal effectiveness
· Latent defect estimation
· Response time
· Project progress
· Combinations of these areas
Examples of process-performance models include the following:
· System dynamics models
· Reliability growth models
· Complexity models
Refer to the Quantitative Project Management process area for more information about the use of process-performance models.
Typical Work Products
1. Process-performance models
Subpractices
1. Establish the process-performance models based on the organization’s set of standard processes and the organization’s process-performance baselines.
2. Calibrate the process-performance models based on the organization’s past results and current needs.
3. Review the process-performance models and get agreement with relevant stakeholders.
4. Support the projects’ use of the process-performance models.
5. Revise the process-performance models as necessary.
Examples of when the process-performance models may need to be revised include the following:
· When the processes change
· When the organization’s results change
· When the organization’s needs change
