You are in charge of a project. Your team has determined that there are 7 activities to be completed. Here are the activities, the time to complete the activity and the immediate predecessor of the activity. Using this data 1) construct a Gantt Chart, 2) determine the time it will take to complete the project, 3) You are monitoring the progress of this project and discover that activity C is in danger of taking longer than planned due to funding issues. What options do you have to get the project back on track? Activity Time Immediate Predecessor A 10 Weeks None B 6 Weeks A C 7 Weeks A D 6 Weeks B E 8 Weeks C F 3 Weeks D G 4 Weeks F

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?

1.15 Given the following financing project being considered by a venture firm, find the probability of completing the path with the longest expected duration by 17 weeks. By 24 weeks. By what date is management 90 percent sure that this path will be completed? refer to first pic If the venture firm can complete the project for the customer within 18 weeks, it will receive a bonus of $10,000. But if the project delays beyond 22 weeks, it must pay a penalty of $5,000 due to lost opportunity.  If the firm can choose whether or not to bid on this project, what should its decision be if the project is only a breakeven one normally?
