Abstract

The increasing design, manufacturing, and provision complexity of high-quality, cost-efficient and trustworthy products and services has demanded the exchange of best organizational practices in worldwide organizations. While that such a realization has been available to organizations via models and standards of processes, the myriad of them and their heavy conceptual density has obscured their comprehension and practitioners are confused in their correct organizational selection, evaluation, and deployment tasks. Thus, with the ultimate aim to improve the task understanding of such schemes by reducing its business process understanding complexity, in this article we use a conceptual systemic model of a generic business organization derived from the theory of systems to describe and compare two main models (CMMI/SE/SwE, 2002; ITIL V.3, 2007) and four main standards (ISO/IEC 15288, 2002; ISO/IEC 12207, 1995; ISO/IEC 15504, 2005; ISO/IEC 20000, 2006) of processes. Description and comparison are realized through a mapping of them onto the systemic model.
