- The company decided that the project in the previous problem had to be expedite in order to optimize (minimize) the project cost. Expediting can be used to trade direct cost for indirect cost, since expediting reduces the indirect cost of the project by a fixed amount per day, while expediting an activity increases its total direct cost. The Accounting Department found that indirect costs amount to $100 per day, while activity direct costs as well as their normal and expedited times are given in the table below. Activity Duration (Days) Expedited Time (Days) Normal Direct Cost ($) Expedited Direct Cost ($) A 32 26 200 500 B 21 20 300 375 C 30 30 200 200 D 45 40 200 800 E 26 20 700 1,360 F 28 24 1,000 1,160 G 20 18 400 550 What is the optimal time to complete the project?

- Project crashing is when you shorten the duration of a project by reducing the time of one or more tasks. Crashing is done by increasing the resources to the project, which helps make tasks take less time than what they were planned for. Of course, this also adds to the cost of the overall project. Therefore, the primary objective of project crashing is to shorten the project while also keeping costs at a minimum. What are the different options for crashing an activity when resources are not constrained ?arrow_forwardAt times, in order to monitor the project planning, a project manager can resort to the development of a project planning by starting at the end of the project and back to the beginning. Which allows the project manager and try to identify and measure the length of the tasks that will potentially require up to the period of time the project is scheduled to take. Although this might seem to be a rational solution to preparing a project plan, the use of this tactic may significantly decrease the likelihood that the project meets its deadline. If you think that this strategy is right to build a project schedule? Talk about the rationale behind your reply. Discuss that this plan will significantly reduce the likelihood that the project would reach its deadlinearrow_forwardYou have been assigned as a Project Manager in your Company.
