The Peabody Coal Corporation recently completed the final feasibility report for a new general ledger accounting system. It has hired a consulting firm to program and install the new system. The consulting firm is charging $350,000 for the remaining tasks to be performed. These tasks are to be performed over the next 10 months as detailed in the Gantt chart in the diagram. The consulting firm is extremely concerned with the project staying on schedule because it is receiving a flat fee. The release of the final payment is contingent upon the system performing as stated in the contract and upon Peabody receiving appropriate documentation of the system.Requireda. Prepare a PERT diagram and indicate the critical path.b. What happens to the time frame of the implementation of the project if the manufacturer is 4 weeks late shipping the hardware?c. What happens if the data conversion does not go smoothly and takes an additional 3 weeks? d. Who should conduct the postimplementation review?…

- Farihah is a project manager for a systems development project involving a new database application for her organization’s human resources department. Despite Farihah’s best efforts at estimating the time requirements for the project, the team has missed the deadline for completing the Analysis Phase and producing the System Proposal. Farihah had estimated during her 6-week Planning Phase that Analysis would require 2 months, but the team finished the System Proposal 2 weeks behind their planned target date. Based on her discussions with the team members, Farihah believes that the system is more complex than she originally thought. Should Farihah adjust her timeline, or can she try to make up for the lost two weeks? Farihah needs your advice.arrow_forwardKelle Carpet and Trim installs carpet in commercial offices.

It is 30 per cent completed. Earned Value analysis shows that the project is not achieving its planned cost or progress targets. The project is also not achieving quality requirements. Some of the specialized components used for this project are only obtainable from overseas suppliers and are difficult to transport over the rough terrain near the project site. There has been a delay on ordering these components. The transportation of these components, which must be booked several months ahead, has not been arranged, and there is also difficulty with obtaining tradespeople with the requisite set of skills to install them. There are also several other risks associated with this project, including a quite basic business case, rudimentary project charter, poor definition of expected project outcomes, exchange rate risks and the potential for…arrow_forward
