If you are working on the project for Company ‘B’, then please write at least 6 major Risk factors, you can foresee, that may arise during the execution of the project. You are also required to recommend the risk mitigation (risk control) steps against each risk.
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 ?
Hi, I need help answering the last question.
Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible. In order to meet this objective a number of activities must be crashed.
