This paper looks at several aspects of process infrastructure and maturity from the viewpoint of systems thinking concepts. To start, the paper addresses the position of process infrastructure relative to ISO 15288 (ISO/IEC, 2002) enabling systems. Next, the paper looks at the impact of multiple standards on the infrastructure and the programs using it. A third view is the use of a systems approach to deal with the problem of multiple standards for how processes are implemented. The final view is how the common features implement both the science and engineering approach activities and how maturity levels address them.
