One of the main buzzwords during last 20 years is “maturity model” (MM), moving from the original Crosby’s idea. A plenty of MMs was created also in Project Management with OPM3, PM2 and PMMM just to name a few. Even if most of such models have been discussed, there is room for new issues to observe (e.g. those MMs are proposed in a staged and not continuous representation, and there are no enough mappings available).
The paper focuses on the way to achieve improvements in organizational as well as process maturity with a 360° view, using jointly “horizontal” MMs (models containing all the processes to be sequentially executed in a value chain, as CMMI) and “vertical” MMs (models deepening a group of processes within the organization’s BPM, as PMI’s OPM3). The paper will discuss the way to combine assessment results using more MMs on the two dimensions, with a general-domain approach as well as examples from the Software/Systems Engineering domain, optimizing the effort for conducting those appraisals in an organization, as well as how to use them in the context of the IPMA Competency Baseline v3.0 and PMI Project Management Competency Development Framework v2.0.
