Time Pressure in Megaprojects: Origins, Consequences, and Management Strategies

Purpose: To integrate fragmented literature on time pressure in megaprojects and develop a mechanism-oriented explanation of how pressure emerges, escalates, and affects project outcomes. Design/methodology/approach: A conceptual synthesis draws together research on megaproject governance and performance, psychological theories of stress and decision-making, and studies on team learning and project execution. The article develops a dual-pathway framework that distinguishes planning-origin and execution-origin time pressure. Findings: Time pressure in megaprojects arises both from front-end schedule compression and from execution-stage deviations that trigger recovery action. Under conditions of high interdependence, limited capacity, and elevated success pressure, both pathways can activate a self-reinforcing Vicious Pressure Circle in which acceleration, process bypassing, rework, lower acceptance thresholds, and re-planning intensify subsequent pressure. Expertise, psychological safety, modularization, and reference-class forecasting operate as moderating mechanisms. Research limitations/implications: The framework is conceptual and therefore requires empirical testing across project types, governance regimes, and lifecycle phases. Practical implications: Project organizations should distinguish the origin of pressure, monitor requirement-capacity mismatches, protect reporting climates, and use front-end realism and modular design to interrupt escalation loops. Originality/value: The article offers a unified conceptual vocabulary and explicit propositions that connect megaproject governance, cognitive mechanisms, and organizational learning.
