Let us revisit the project data from Question 7 of Homework #2, where all times are in days (and it is understood that the duration of activity A can be no less than 3 days, in which case it costs $150 instead of $50, and so on and so forth).

MODELLING AND SIMULATION 1. What is the best way to plan a simulation project? Why? 2. Does project management help you to simulate a model? In what way/s? 3. Car dealers have realized how profitable it can be to sell automobiles by using the Web. Pretend that you work for a local car dealership that is part of a large chain of car industry. Create a project management process (include the sub-processes) that you will implement in developing such web-based system.
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?

Your vice president asked you what the Estimate at Completion (EAC) will be for a small project you are working on. You were given a budget of S50,000, and to date you have spent $40,000 but only completed $30,000 worth of work. You are sure the future work will be accomplished at the planned rate. What is the EAC ?
