. 1. Project Scope & Constraints The new payroll system project has been approved. The new system will reduce clerical time and errors, improve morale in the payroll department, and avoid possible fines and penalties for noncompliance. The system must be installed by January 1st to meet new federal reporting rules, all expenses must be approved in advance, and the system should have a modular design if possible. The new system is expected to be announced in a year-end report if it is ready by mid-December. 1. Why is it important to define the project scope? How would you describe the scope of the payroll project in this case? 2. Based upon the project scope, identify the constraints, and determine its characteristics: present versus future, internal versus external, and mandatory versus desirable. 3. What questions would you ask to determine the feasibility of this project? 4. Given the project time constraints, could you shorten the typical steps in the preliminary investigation…

The following eight activities constitute an overall bar chart portrayal of a 4-month project. Two months after the start of the project. Activities A, C, D are completed, E is 50% complete and B is 25% complete. The total cost that has been spent is $10,500. For this project, using earned value concepts, determine the schedule and cost variance. Is the project ahead or behind schedule? Over or under budget?
