What does the paper cover?
This paper addresses a recurrent topic of organisational project management research, that in principle, PMOs are perceived to be instrumental in implementing strategy through portfolios of projects, but empirical evidence also shows that PMOs are often short-lived and their value is hard to quantify. The authors argue that an explanation may lie in the processes of co-evolution that PMOs undergo over time in interaction with organisational capabilities and context.
The authors established their conceptual process model in three steps:
- PfM was conceptualised as a collection of routines forming an organisational capability.
- PMO was conceptualised as an organisational meta-artefact, an organisational sub-system designed to provide a solution to a type of problem (in this case, PfM).
- The relationships between the PMO, PfM and the broader organisation were mapped onto a process model of routine (re)creation.
Proteus was used as a case study of a project-based organisation to test, refine, and validate the process model, with data collection using interviews, observations, and documents.
The research leads to the formulation of six propositions related to patterns of change in PMOs, two conceptual (P1, 4) and four theoretical (P2, 3, 5, 6):
P1: The PMO, as an organisational sub-system, can be conceptualised as a meta-artefact.
P2: Changes of artefact element of PMO routines impact PfM through influencing the artefact element of PfM routine.
P3: Changes in the performative element of PMO routines impact PfM through influencing the performative element of PfM routine.
P4: PfM as an organisational capability can be conceptualised as a collection of routines.
P5: Changes in the ostensive elements of PfM routines impact the PMO through influencing the ostensive or performative elements of PMO routines.
P6: Changes in the performative elements of PfM routines impact the PMO through influencing the ostensive or performative elements of PMO routines.
The process change model suggests that managerial interventions may trigger multiple changes, some of which may not be intended. It reinforces the value of managerial reflectiveness and the need for organisational learning and knowledge management to capitalise on beneficiary evolutions.
Starting from the observation of the short life-span of many PMOs and their questionable performance, the authors highlighted that studying the evolution of PMOs alone was not sufficient, and that considering the dynamic interplay between the PMO and the organisational context and systems was more appropriate.
The authors proposed an initial conceptual framework of PMO and PfM co-evolution, which was tested and refined using a single empirical case study. After discussing the findings, they then offered a revised conceptual framework for the co-evolution of the PMO and PfM. Based on this framework, there were six propositions outlined. Both the conceptual framework and the propositions need to be strengthened, and three concomitant and complementary research projects are underway.
