Resource levelling is a technique in project management that oversees resource allocation to prevent over-allocation and resolve conflicts. It ensures resources are properly allocated to benefit the organization by delivering projects on time without conflicts. An organization can face problems if some resources are over-allocated while others are under-allocated, bringing financial risk. Resource levelling helps maximize use of available resources by reducing wastage from over-allocation and identifying unused time that can be utilized. It aims to increase project efficiency by properly using resources at hand without heavy expenditure.
