External Stakeholder Management in Projects: Taking Stock and Moving Forward

External stakeholders including communities, user groups, interest organisations, and non-contractual actors are pivotal to project legitimacy and outcomes across sectors. The chapter first outlines why managing external stakeholders is both a strategic necessity and a complex challenge shaped by plural interests, institutional contexts, and evolving societal expectations. Following this, it takes stock of existing work by synthesizing current research, identifying progress in governance frameworks, participatory practices, and methodological innovation, alongside gaps in theory integration, cross-context analysis, stakeholder identification, and outcome measurement. The collection of chapters in this book progress logically from foundations and identification, through policy and practice, to special contexts with positive exemplars. The chapter proposes a research and practice agenda centred on multi-theoretical perspectives, adaptive governance, sustainability, and robust evaluation. It is argued that effective external stakeholder management should be embedded as a proactive, value-creating capability in project strategy, ensuring not just project delivery but enduring social legitimacy.
