The Automotive SPICE Process Assessment Model (PAM) has been developed by consensus of the car manufacturers within the Automotive Special Interest Group (SIG) of the joint Procurement Forum/SPICE User Group under the Automotive SPICE initiative.

8 The Automotive SPICE Process Assessment Model (PAM) is available for use when performing conformant assessments of the software Process capability of Automotive suppliers in accordance with the requirements of ISO/IEC 15504-2. The Automotive SPICE Process Reference Model (PRM) is used in conjunction with the Automotive SPICE Process Assessment Model (PAM) when performing an Assessment . The Automotive SPICE Process Reference Model (PRM), which is defined in a separate document, is derived from Annex F and H of ISO/IEC 12207 AMD1: 2002 and ISO/IEC 12207 AMD2: 2004. It contains a sub set of the processes with minor editorial changes together with a number of other changes to reflect consistency in use of terminology and application in the Automotive sector.

9 The FULL scope of Automotive SPICE contains ALL the processes from the ISO/IEC 15504 Process Reference Model (PRM). The fact that some processes have not been included within the Automotive SPICE PRM does not mean that they are not valid. Supplier organisations should address all processes relevant to their business needs within their organisation. Where a Process is not included within the Automotive SPICE Process Reference Model (PRM) then the relevant Process should be included from the ISO/IEC 15504 exemplar Process Assessment Model . The manufacturers will however focus on the set of Process defined within the Automotive SPICE PRM when performing supplier capability assessments. This Automotive SPICE Process Assessment Model contains a set of indicators to be considered when interpreting the intent of the Automotive SPICE Process Reference Model .

10 These indicators may also be used when implementing a Process improvement program following an Assessment . The SPICE User Group 2005-2010 9 Definitions PAM Process Assessment Model PRM Process Reference Model SIG Special Interest Group SPICE software Process Improvement and Capability dEtermination Terminology Automotive SPICE follows the following precedence for use of terminology: a. English dictionary for common terms b. ISO/IEC 15504-1 :2004 for Assessment related terminology c. IEEE 630 and BS 7925-1 terminology (as contained in Annex C) This document should be read in conjunction with ISO/IEC 15504-1 :2004. Many terms from ISO/IEC 15504-1 :2004 are used throughout the document. Other terminology used is defined below Application parameter An application parameter is a parameter containing indispensable/essential data applied to the system affecting overall system functions, behaviour or properties.
