Establishing a Generic and Multidimensional Measurement Repository in CMMI context

We propose a measurement repository for collecting, storing, analyzing and reporting measurement data based on the requirements of the Capability Maturity Model Integrated (CMMI). Our repository is generic, flexible and integrated, supporting a dynamic measurement system. It was originally designed to support Ericsson Research Canada’s business information needs. Our multidimensional repository can relate measurement information needs to CMMI processes and products requirements. The data model is based on a hierarchical and multidimensional definition of measurement data. It has been developed based on the concept of a data warehouse environment. Reporting features are based on the definition of queries to On Line Analytical Process (OLAP) cubes. OLAP cubes are created as materialized views of the measurement data, and the user functionalities are implemented as analytical drill-down/roll-up capabilities and as Indicator and Trend Analysis capabilities.
