The new computer-controlled conveyor belt is an exciting project that moves and positions items on the conveyor belt within < J millimeter. The project will produce a new system for future installations, and for replacement of those in the field, at a low cost. The computer-controlled conveyor belt has the potential to be a critical unit in 30 percent of the systems installed in factories. The new system is also easier to update with future technologies. The Project Priority Matrix for the Conveyor Belt Project (CBP) is:

Does this information (WBS) allow you to define any milestones of the project? Why why not? What are they? Remember: Save your file for future exercises!
Use your file from Part I and the information provided below to complete this exercise. (See Table A2.7.) 1. Each work package will represent an activity. 2. The project begins January 4, 2010. 3. The following holidays are observed: January I, Memorial Day (last Monday in May), July 4th, Labor Day (first Monday in September), Thanksgiving Day (4th Thursday in November), December 25 and 26. 4. If a holiday falls on a Saturday then Friday will be given as an extra day off, and if it falls on a Sunday, then Monday will be given as a day off. 5. The project team work eight-hour days, Monday through Friday. Warning: Experience has taught students to frequently make separate backup files for each exercise. The software is never as friendly as users expect! Construct a network schedule for the conveyor belt project and prepare a memo that addresses the following questions: 1. When is the project estimated to be completed? How long will the project take? 2. What is the critical path(s) for the project? 3. Which activity has the greatest amount of slack?

4. How sensitive is this network? 5. Identify two sensible milestones and explain your choices. 6. Compare the advantages/disadvantages of displaying the schedule as a network versus a Gantt chart. Include the following printouts: • A Gantt chart. • A network diagram highlighting the critical path. • A schedule table reporting. ES, LS, EF, LF, and...
