Purpose The conceptual and modularization of project management maturity models is based on the principle of process control. This research was designed to challenge these boundaries to reveal non-process factors. The paper aims to discuss these issues. Design/methodology/approach A multimethod research design was used with a “qual⇒Qual” sequence. This is a development in MM design theory, with its reliance on an initial qualitative stage that, despite being first, is insufficient to collecting sufficient data to answer the research question. A second stage, involving a more dominant qualitative, is necessary.
