1Scope1.1IntroductionProcess assessment is a disciplined evaluation of an organizational unit’sprocesses against a Process Assessment Model (PAM).The Automotive SPICE Process Assessment Model (PAM) has beendeveloped by consensus of the car manufacturers within the AutomotiveSpecial Interest Group (SIG) of the joint Procurement Forum/SPICE UserGroup under the Automotive SPICE initiative.The Automotive SPICE Process Assessment Model (PAM) is available foruse when performing conformant assessments of the software processcapability of automotive suppliers in accordance with the requirements ofISO/IEC 15504-2.The Automotive SPICE Process Reference Model (PRM) is used inconjunction with the Automotive SPICE Process Assessment Model (PAM)when performing an assessment.The Automotive SPICE Process Reference Model (PRM), which is definedin a separate document, is derived from Annex F and H of ISO/IEC 12207AMD1: 2002 and ISO/IEC 12207 AMD2: 2004. It contains a sub set of theprocesses with minor editorial changes together with a number of otherchanges to reflect consistency in use of terminology and application in theautomotive sector.The FULL scope of Automotive SPICE contains ALL the processes from theISO/IEC 15504 Process Reference Model (PRM). The fact that someprocesses have not been included within the Automotive SPICE PRM doesnot mean that they are not valid.Supplier organisations should address all processes relevant to their businessneeds within their organisation. Where a process is not included within theAutomotive SPICE Process Reference Model (PRM) then the relevantprocess should be included from the ISO/IEC 15504 exemplar ProcessAssessment Model. The manufacturers will however focus on the set ofprocess defined within the Automotive SPICE PRM when performingsupplier capability assessments.This Automotive SPICE Process Assessment Model contains a set ofindicators to be considered when interpreting the intent of the AutomotiveSPICE Process Reference Model. These indicators may also be used whenimplementing a process improvement program following an assessment. The SPICE User Group 2005-20108
