Problem Statement: Project Control and Monitoring You are working on a manufacturing project having a budget of PKR 3,600,000 and expected time of its completion is one year. There is an ideal condition that your budget and work are evenly spread across the duration of the project that is twelve month. At the end of forth month, the senior management has called a meeting and invited all the stakeholders to brief about the status of the project. You being the PM of this project is giving the presentation to all the attendees and informed that project is on schedule and PKR 1,800,000 have already been spent on the project. Required: Calculate Cost and Schedule Variance What is SPI and CPI of the project? Estimate at completion and Estimated time to complete?
Image of Diagram included Using the diagram, find: The critical path. How long it will take to complete the project? How does simulation determine the probabilities of various project completion times? What is "slack" and why is it important? Why is activity-on-arrow (AOA) or activity-on-node (AON) of significant value to the project manager? How is the uncertainty in project scheduling dealt with? Should the critical path activities be managed differently from noncritical path activities? Explain.
