The ISO/IEC 15504 series of standards provides a model for assessing processes known as SPICE (Software Process Improvement and Capability Determination).
This maturity model is used to demonstrate the maturity level at a specific point in time by means of assessment.
There is also an industry-specific interpretation Automotive SPICE or ASPICE, which was published by the "Automotive Special Interest Group". This includes the companies Audi, BMW, Daimler, Fiat, Ford, Jaguar, Land Rover Porsche, Volvo and VW as well as the "Procurement Forum" and the "SPICE User Group".
This standard was derived from the international standard ISO/IEC 15504, which deals with the analysis, evaluation and improvement of processes in software-based system development. The name "SPICE" stands for "Software Process Improvement and Capability Determination". In the meantime, ISO/IEC 15504 has been replaced by a revised series of standards, the ISO/IEC 330xx series. Automotive SPICE® has defined its own Process Reference Model (PRM) and Process Assessment Model (PAM) based on the latest version of the ISO/IEC 330xx series. These models describe the processes as well as indicators for the uniform assessment of these processes.
