Crashing vs Fast Tracking

Difference between Crashing and Fast Tracking in Project Schedule Management


  • Both crashing and fast-tracking are schedule compression techniques.
  • Both techniques aim to compress the project schedule without compromising on the scope.


Crashing is a schedule compression technique that involves determining an approach that brings maximum reduction in project duration with least incremental cost and risk, and without changing the scope.

Drawbacks of Crashing

  • Increased Risks
  • Increased Costs
  • May not always result in a compressed schedule

Fast Tracking

Fast tracking is a schedule compression technique that reduces the project duration by performing critical path activities in parallel that were originally planned to be performed in sequence.

Drawbacks of Fast Tracking

  • Increased Risks
  • Rework

Differences between Crashing and Fast Tracking

  • In crashing, schedule is compressed by applying additional resources, working overtime, etc. Whereas in fast tracking, activities which are usually performed in sequence are performed in parallel, to compress the schedule.
