could i have help for part b, c, d, e

A company produces advanced robotic devices for laboratories and other environments having stringent requirements for contamination avoidance and protection. It has decided to invest in an upgrade to its coating application facility in order to increase capacity and handle new devices that are being developed for future production. A work breakdown structure has been developed to show the main tasks involved in the upgraded project, as indicated below. The estimated durations of each task, and the pre-requisite tasks that have to be completed before a task can startare also shown Work brown Prerequisites Duratio/web Design DI General arrangements D2 Subcontracted detailed design DI D3 Assurance and approval D2 Procurement PI Contractor search P2 Contractor shortlisting PI P3 Enquiry P2.

Then find the critical path in this case and the minimum project duration - question continues over b) Explain what further procedures are required to find the critical path in PERT and outline the rationale for doing this. Then suggest why an organization might be reluctant to use PERT, and give (with reasons) your opinion of whether PERT is useful overall c) Briefly state the reasons for planning projects despite the notorious failure of plans in practice. Then suggest, with justification, which reasons you think would be more important in this case. The company decides to control the project using Famed Value Analysis. After 5 months following the start of the project the project manager has the following table of expenditure and value of work completed at the end of each of the 5 months. The total cost of the project was estimated at 5.4M.
