Differentiate between lag time and slack time, and critical path and critical path driven delay in project management.

Here are the solutions to your questions:

1. Differentiate between the following terms as used in project management:

• a) Lag time and slack time

  • Lag time is an intentional delay inserted between activities, meaning a successor activity cannot start until a specified period has passed after its predecessor, even if the predecessor is complete.
  • Slack time (or Float) is the amount of time an activity can be delayed without delaying the project's overall completion date or violating a schedule constraint.

• b) Critical path and critical path driven delay

  • The critical path is the longest sequence of activities in a project network diagram, determining the shortest
