The process assessment model (PAM) of Automotive SPICE defines base practices for capability level CL1 and general practices for higher capability levels. In ASPICE assessments, the rating of these practices is used to determine the capability level of a particular process in the assessment scope. There are five capability levels: CL1 – Performed. CL2 – Managed. CL3 – Established. CL4 Predictable. CL5 – Innovating.
