ISO/IEC 15504 measurement applied to COBIT process maturity

Purpose – The assessment of COBIT process maturity levels is fraught with a number of problems regarding the objectivity of the assessment results. Unlike ISO/IEC 15504, COBIT does not define an assessment model. The purpose of this paper is to align the behavioural aspects of the six COBIT process attributes with achievement results defined for the nine process attributes associated with the ISO/IEC 15504‐2 measurement scale. The authors believe that this alignment permits a translation of the ISO/IEC 15504 assessment data into an objective COBIT process maturity rating.Design/methodology/approach – The tables presented in the paper identify the COBIT process attributes, the applicable ISO/IEC 15504 process attribute achievement results and the aggregated rating that pertains to the selected achievement results. A final table lists the derived COBIT process maturity level in terms of the ratings for the ISO/IEC 15504 process attribute achievement results for an assessed process.Findings – The objectivity...
