Questions from this subtopic

Each one with the model answer underneath.

  1. 1

    What does critical path analysis tell a business about the project duration?

    Model answer

    The earliest start time at the final node gives the shortest possible completion time. No arrangement of the same activities finishes sooner. The figure is therefore the project's minimum duration.

  2. 2

    How does critical path analysis help with resource allocation?

    Model answer

    Activities with float can be delayed or given fewer resources without harming the completion date. Resources can therefore be moved to the critical activities where delay is costly.

  3. 3

    What is meant by just-in-time ordering in the context of a network?

    Model answer

    A network shows exactly when each activity begins, so materials can be ordered to arrive at that point. Holding costs fall because stock does not sit waiting.

  4. 4

    Give two benefits of critical path analysis.

    Model answer

    The technique establishes the shortest completion time and shows which activities must not slip. Identifying float also allows resources and cash to be scheduled efficiently.

  5. 5

    Give two limitations of critical path analysis.

    Model answer

    The durations are estimates, and one wrong estimate changes the whole schedule. The network also assumes resources are available whenever an activity is due to start.

  6. 6

    Why does a complex project make the technique harder to use?

    Model answer

    A network with hundreds of activities is difficult to draw and difficult to read. Circumstances change during a long project. Keeping the network current then takes considerable management time.
