Project Description

The industry-specific standard Automotive SPICE (Software Process Improvement and Capacity dEtermination), derived from the ISO 15504 International Standard for software process assessments, was published in 2005. Automotive SPICE has its Process Reference Model (PRM) and Process Assessment Model (PAM).


Automotive SPICE includes two dimensions:  the Process Dimension and the Process Capability dimension.
  • The processes in the process dimension are based on ISO 12207, with extension and modification for automotive purpose.
  • The process capability dimension addresses the six process capability levels in ISO 15504. The ISO 15504-compatible assessment model is for conducting assessments.

Capability Level Dimension

  • Level 0 – Not all processes are carried out and therefore certain important work products (plans, specifications, design documents, test descriptions etc) do not exist.
  • Level 1 – all important documents are available.
  • Level 2 – everything is systematically planned and tracked.
  • Level 3 – there are uniform guidelines for the complete organization.
  • Levels 4 and 5 – the processes are statistically measured and optimized.

Process Dimension

This below figure lists the processes addressed by ISO 15504.
The processes that have been adjusted or added for Automotive SPICE are marked in orange. The HIS scope, highlighted in blue, is the minimum requirement of the processes to be examined in an assessment.
