Manage and store measurement data, measurement specifications, and analysis results.

Storing measurement-related information enables its timely and cost-effective use as historical data and results. The information also is needed to provide sufficient context for interpretation of data, measurement criteria, and analysis results.

Stored information contains or references other information needed to understand and interpret the measures and to assess them for reasonableness and applicability (e.g., measurement specifications used on different projects when comparing across projects).

Typically, data sets for derived measures can be recalculated and need not be stored. However, it may be appropriate to store summaries based on derived measures (e.g., charts, tables of results, or report prose).

Interim analysis results need not be stored separately if they can be efficiently reconstructed.

Projects may choose to store project-specific data and results in a project-specific repository. When data are shared across projects, they may reside in the organization’s measurement repository.

Refer to the Establish the Organization’s Measurement Repository specific practice of the Organizational Process Definition process area for more information about establishing the organization’s measurement repository.

Refer to the Configuration Management process area for more information about managing measurement work products.
