Abstract

The evaluation of CMMI practice in an organization is complex and time-consuming, particularly the readiness review (RR) process; therefore, a precise and accurate assessment methodology and a systematic toolbox are required. This study introduces the Re-engineering Readiness Review Process Performance (R3P2) model, in which a set of performance measures is established and an integrated toolbox, the PPM Suite, is proposed. The model consists of (1) a document management tool for shared, reusable documents; (2) a project management mechanism to facilitate mapping between documents and CMMI practices; and (3) a set of metrics to standardize process improvement by providing a common understanding of how to define quality. The evaluation result on the real appraisals of 308 case studies in four primary and four secondary metrics demonstrates that our R3P2 models improve appraisal performance over the baseline, the non-IT version, by an average of 32.35 and 69.04 % for R3P2-2016 and R3P2-2017, respectively. In addition, the most recent version, R3P2-2017, outperforms its predecessor, R3P2-2016, by approximately 45.42 % on average and in the majority of metrics, including maturity level delivery, customer satisfaction, cycle time delay, and assessment gap, customer expectation, cycle time delay variability, and readiness review process capacity, with the exception of gap variability.
