The COBIT 5 Process Assessment Model (PAM) is based on the international standard ISO/IEC 15504-2 standard. This standard comprises a process dimension (the COBIT 5 PRM) and a capability dimenison (the process attributes).
The assessment approach for conducting a COBIT 5 assessment is detailed in the COBIT 5 Assessor Guide.
The ISO 15504 process attributes for capability improvement provides an evolutionary, logical, reliable and robust methodology for improving the capability of the IT processes.
Higher levels of capability indicate greater sophistication in the ability of management to direct and control the assigned work.
