Procedures involved were shortened or fast-tracked to speed up the project. 1. 3. For example, the plan for afour-lane highwaymayreduce its scope tobuilda two-lane highwayinsteadto reducethe timerequiredforcompletionandto meetimmediate needs. In slightly simpler terms, crashing a project means speeding up the project by employing additional resources, in cases where the project scope and the project deadline cannot be changed. For example, the plan for afour-lane highwaymayreduce its scope tobuilda two-lane highwayinsteadto reducethe timerequiredforcompletionandto meetimmediate needs. Of course, this also adds to the cost of the overall project. by one week with an extra cost of Rs. You may find diverse ways to add resources to a project depending on what is causing the delay or taking a lot of time. Figure 4: ASSA ABLOY's process for manufacturing padlocks. Though were discussing project crashing, its important to touch on when fast tracking is preferable. An example of a project that can utilize schedule crashing is planning a business trip. succeed. depending on the least crash cost per unit time. Since you cant begin the work without this document, its likely that acquiring the permit will be one of the activities belonging to the Critical Path. When you know what you will have to spend (compared to how much time youll save) for each of the tasks in your critical path, you must now make a decision and choose the least expensive way forward. Some projects may involve penalties for missing the completion date. There are ramifications for each of these scenarios. We recommend taking a look at our Critical Path guide to learn more about this topic: Some activities simply cannot be crashed, even though they are part of the Critical Path. Project crashing is triggered by a variety of reasons. Regardless of the money that goes into the project, the time required for testing and waiting to see the effectiveness of the vaccine in the volunteers could not be sped up. and that of E by one week. either E or G for crashing. You may need to advance the completion date of a project even if it is going on track because of an external factor. Project crashing is not just adding resources to get done faster, but its getting the most in return for that extra expense. Nguyen Quoc Trung. Project crashing is a schedule compression technique. Here you will be able to evaluate the trade-off between cost and time on a project, in order to reduce the overall completion time.
