An overlapping relationship in project management occurs when:

An overlapping relationship in project management describes a scenario where teams or tasks do not wait for one another to finish completely before beginning their work. Instead, they can work simultaneously or in close succession on different aspects or parts of the project. This method can enhance efficiency and reduce the overall project timeline by allowing concurrent tasks to progress without the need for a linear approach.

In project management, overlapping can lead to benefits such as faster completion times and better resource utilization. It is particularly useful in large, complex projects where breaking tasks into parallel components can be advantageous.

The other options depict scenarios that do not align with the concept of overlapping relationships. For instance, some options suggest a more sequential approach or isolation of tasks, where teams or phases do not overlap, leading to potentially longer project durations. Understanding the dynamics of task relationships is crucial to effective project management, and overlapping workflows is a strategic choice that can drive project success when managed effectively.
