“…Second, a poorly understood, yet critical governance activity performed by the network orchestrator, is the process of establishing coordination between the network orchestrator and all network members (Pathak et al, 2014). While prior work shows that effective coordination depends on the fit between needs and mechanisms (Gulati et al, 2012; Oliveira & Lumineau, 2017), extant studies provide an incomplete understanding of the formal and informal coordination undertaken by the network orchestrator to govern inter‐organizational project networks (Fortwengel & Sydow, 2020; Reypens et al, 2021). Understanding the effectiveness of coordination mechanisms within inter‐organizational networks in a project setting matters because ineffective coordination can lead to conflict, disputes, and poor project outcomes (e.g., Kalra et al, 2021; van Marrewijk et al, 2016), and leads to our second question: How does coordination by the network orchestrator influence performance outcomes within the ancillary services of a large‐scale project?…”
