5. Process capability levels and process attributes

Process capability indicators are the means of achieving the capabilities addressed by the considered process attributes. Evidence of process capability indicators supports the judgment of the degree of achievement of the process attribute.

The capability dimension of the process assessment model consists of six capability levels matching the capability levels defined in ISO/IEC 33020. The process capability indicators for the 9 process attributes included in the capability dimension for process capability level 1 to 5 are described.

Each of the process attributes in this process assessment model is identical to the process attribute defined in the process measurement framework. The generic practices address the characteristics from each process attribute. The generic resources relate to the process attribute as a whole.

Process capability level 0 does not include any type of indicators, as it reflects a non-implemented process or a process which fails to partially achieve any of its outcomes.
