The Missing System Layer
FEATURED PAPER

In recent years, project management has evolved significantly, incorporating increasingly advanced standards, methodologies and tools. However, when projects are carried out in complex, multi-project environments, recurring problems such as cost overruns, delays and difficulties in decision-making continue to arise, even in mature organisations.
This article proposes that the root cause of these limitations lies not solely in execution, but in the absence of a governance layer designed at the organisational level. Based on this premise, MetaPMO is presented: a framework based on the KPM (Key Process Management) methodology and developed from a research project applied in complex environments.
MetaPMO proposes a different approach to project management: it does not replace existing methodologies, but rather defines how they should coexist, how decisions are made and how information from different systems is integrated. Furthermore, it incorporates artificial intelligence to support improved risk anticipation, cost predictability and organisational learning.
The article covers both the fundamentals of the model and the results observed during its implementation in sectors such as construction and technology, where improvements have been identified in the quality of decision-making, risk management and the role of the PMO.

- Introduction
Over recent years, the field of project management has gained in importance, becoming a highly recognised professional discipline. Companies across various sectors have progressively incorporated into their organisational structures professionals dedicated exclusively to project management, who strive for excellence in project delivery by drawing on international standards, the latest technologies and sector-specific strategies. Project Management Offices (PMOs) are being strengthened, with the primary aim of ensuring projects are executed correctly and on schedule, whilst anticipating potential risks to minimise their impact.
However, this stability is disrupted when we find ourselves in highly complex environments, where projects are carried out amid considerable uncertainty and interdependencies with other teams. Decision-making, strategy formulation and control become reactive, even in organisations that adhere to best practices and international standards. Without a holistic view, it is common to encounter problems such as cost overruns, delays to deadlines and difficulties in monitoring performance. Here I pose a question: why do we find ourselves in a state of chaos in complex contexts despite having methodologies, tools and highly qualified professionals at our disposal?
