Resource management is significantly more challenging in a multi$-$project environment due to competing priorities, limited availability, and interdependencies among projects. Shared resources often face overcommitment, leading to inefficiencies and delays, while dynamic changes in scope or timelines further complicate planning. To address these challenges, project and program managers can centralize resource allocation using tools for visibility, prioritize projects strategically based on importance, and reserve resource buffers to handle unexpected demands. Regular communication and coordination between project teams are essential, as is limiting task$-$switching by reducing resource splitting across projects. Designating a resource manager and employing phased planning, like rolling wave planning, can further streamline resource management. By monitoring utilization and adjusting allocations as needed, managers can effectively balance competing demands and improve project outcomes.
