Which term is defined as a constrained resource that drives scheduling?

The term that is defined as a constrained resource that drives scheduling is a bottleneck resource. In project management and scheduling, a bottleneck resource is one that has limited capacity compared to the demand placed on it. This limitation affects the overall throughput of the project. When a resource is identified as a bottleneck, it can significantly influence the project schedule, as it represents the maximum amount of work that can be processed.

Focusing on a bottleneck allows project managers to prioritize tasks that utilize this critical resource in order to optimize the overall project timeline. Managing bottleneck resources effectively is crucial for ensuring that projects stay on track and deadlines are met. Resources that are not constrained do not have the same level of impact on scheduling and overall project flow.
