- 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_forwardA project has three tasks and three members. These tasks include preparing a bill of materials task and preparing an estimated task must be the project team's responsibility, while the project manager is considered accountable for these tasks. For the Preparing estimate task, the sponsor must be informed. The third task, sending procurement documents task is the responsibility of the project manager, while the project team is accountable for this task, in the other hand the sponsor indeed must be informed of this task. Decide what is the suitable chart type that can be used to list the above tasks and mapped to everyone involved in the project using samples (R, A, C, I). Elaborate your answer by providing the full meaning of those samples and create the table that represents the relationship between these tasks and the samples.arrow_forwardGive typed full explanationarrow_forward
- You are managing a large construction project that’s been broken down intosub-projects (or phases). Each of these sub-projects is scheduled to takebetween three and six months to complete. At the end of each sub-project,you plan to go through the closing processes and document lessons learned.Which of the following BEST describes what you must do at the beginning ofeach sub-project or phase?A. Develop the preliminary scope statement for the phaseB. Make sure you don’t involve the team, to avoid introducing too much projectmanagement overheadC. Use the Earned Value Technique to decide whether or not to finish the projectD. Release all resources from the project and contact sellers to renegotiate allcontractsarrow_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_forwardThe 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?
