![]() ![]() This will result in reduced overall duration as follows:Īfter applying the Crashing technique, the project duration decreased and now it is only 20 days. Also, need to set the ”Duration Type” to ”Fixed Units/ Time”. To apply the Crashing technique, we add one additional resource to all activities. This image shows 4 activities that all are on the critical path and the overall duration of the project is 27 days. In order to understand the concept of Crashing, the following example from Oracle Primavera P6 is presented: If any other path has become critical, then the above steps shall be performed again to further compress the.After taking due approval from sponsors/approving authorities, the project schedule should be compressed accordingly.Once activities to be compressed are identified, the overall cost associated with this change is to be calculated.Activities that can be completed earlier with minimum cost shall be identified. Identify which activities can be compressed or crashed.How to perform Crashing?īelow are steps to perform the crashing technique: In Crashing, the project schedule is compressed by adding additional resources, working additional hours including double shifts, and by paying bonuses to workers, etc.Ĭrashing actually reduces the duration of the project but with additional cost to achieve this. When Fast Tracking does not work in the required value of schedule compression, Crashing is applied. This is where Fast-Tracking is more useful as it decreases project duration significantly. Here, performing different activities in parallel results in a reduced project duration of 21 days. Here, all activities are on a critical path and the total project duration is 30 days.Īfter applying the Fast Tracking technique (performing different activities in parallel), the project schedule may look as below: To understand the concept of Fast-Tracking, the following example from Oracle Primavera P6 is presented: If any other path has become critical, then the above steps shall be performed again to reduce project duration where possible.Need to recheck the schedule if any other path has become a critical path now.Analyze in detail to filter for activities that can be performed in parallel or at least can be performed partially in parallel.List out all activities that are on the critical path.Here, we only consider the activities on the critical path. Project schedule is reviewed in detail.How to perform Fast Tracking?īelow are steps to perform Fast Tracking: Here, not all, but a number of activities can also be performed in parallel. In this technique, we compress the schedule by performing some activities in parallel. Therefore, proper selection and implementation of these techniques are very much necessary to obtain desired schedule compression results. The quality or cost will definitely be impacted in doing so. Schedule compression techniques are required to cover the delays on the project and to meet the target dates as per the contract/baseline. So, the schedule compression technique is mostly required to bring the project back on track. The delays on projects occur due to several reasons, including but not limited to, material unavailability, manpower shortage, work-fronts unavailability, risks, force majeure, poor workmanship, and poor management. Fast Tracking and Crashing, both methods can reduce activity durations, but cost, quality, and risks associated should also be considered while applying suitable techniques. The two key schedule compression techniques offer several advantages and disadvantages depending on their application. ![]()
