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.
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.

We are the project manager for an IT project in our company. We identified the following top-level project tasks and estimated durations to standup a small test lab for the project: Identify test lab building/space requirements and possible locations(8days) Select best location for lab (1day) Once the best location is selected, immediately start the next two tasks: Prepare lab space with power and cabling (3days) Identify/procure required specialized test lab hardware/software(5) Once the lab space is prepared, install/check out available infrastructure hardware/software(1day). Once the specialized software/hardware is received and the infrastructure hardware/software is installed/checked out, install/checkout specialized software/hardware (2days) Once all tasks are completed, conduct the final inspection (1 day). Let's create a PERT/CPM chart for this project and identify the overall project duration and critical path.
