Navigating similarities and differences in governance mechanisms: a systematic review across temporary and permanent interorganizational project networks

Purpose Governance mechanisms guide and regulate networks in pursuit of outcomes. The governance needs of temporary and permanent project networks differ due to distinct sustained collaboration or managed autonomy and interdependence. Temporary project networks are typically established for time-bound goals, while repeated collaboration and strategic alignment can lead to permanent project networks. This study aims to analyze these governance mechanisms across both temporary and permanent project networks, examining their similarities and differences. Design/methodology/approach A systematic review in Scopus and Web of Science databases identified 105 studies, enabling a bibliometric co-occurrence analysis that revealed 4 clusters connected to governance mechanisms. Additionally, categorical thematic analysis focused on formal, informal and hybrid mechanisms. Findings The results indicate that temporary and permanent project networks apply governance mechanisms in distinct but complementary ways. Temporary project networks tend to require more contractual rigidity, whereas permanent project networks benefit from more informality, fostering long-term stability and trust. Informal mechanisms developed in temporary project networks may support the longevity of future networks. This study also discusses hybrid mechanisms, which inherently combine formal and informal concepts. Originality/value The study highlights a “core” of governance mechanisms in project networks and explores hybrid mechanisms that bridge formal and informal approaches. For managers, it emphasizes the need for contractual clarity and flexibility clauses to allow adjustments within temporary project networks. In contrast, in permanent project networks, they are advised to focus on fostering long-term stability and collaborative relationships.
