One effective approach to address this issue is to improve the system of production planning and control (PP&C). This strategy, as per the literature, had evolved to include up to four different types of PP&C mechanisms that are related to ´business´, ´production´, ´virtual´, and ´complex´ aspects. Nonetheless, despite the progress, PP&C still disregards various complexity-related aspects. To address this issue, we analyzed the concept of the ´Complexity of PP&C´. This paper discusses its definition, elements, and role. It was found PP&C complexity involves three aspects: project complexity, outcomes complexity, and structural complexity. Thus, we conceptualized PP&C complexity as a feature of the behaviour of outcomes that emerge to answer project stimulus driven by the interaction between the elements of the structure of PP&C, a feature that is both a risk and an opportunity for performance improvement. This perspective offers new insights for PP&C evolution and improvement, although further work is still required. KW - Production planning and control KW - complexity.
