The process assessment model (PAM) aligns with COBIT 4.1 and ISO/IEC 15504-2.
ISO/IEC 15504-2 provides a sound standard for the assessment of the capability of a process to achieve its required outcome. The current COBIT process maturity addresses process maturity based on generic attributes, both approaches use 5 levels of assessment but the new COBIT assessment process is different because it provides a more robust, dependable assessment approach to deliver more consistent results and performed by certified assessors.
A training and certification program for assessors is in development.
Note: In the ISO/IEC 15504 world, a significant detailed process assessment takes place at level 1, where the "specific" COBIT process activity assessment is done. ISO/IEC 15504 prescribes generic outcomes, base practices and work products to be assessed at the higher capability levels.
