1. Determining Critical Path and Activity Slack
Assume we have a set of activities, their expected durations, and immediate predecessors. Enter this information using MS Project to produce a Gantt chart - enable project summary.
(a) Identify the critical path.
(b) Identify activity slack times that are non-zero and record in the table below.

Now, now assume that activity C has taken 8 days past its anticipated duration to complete.
(c) How does the project's schedule duration change?
(d) Why does the duration change?
(e) Is there a new critical path? If so, what is it?
2. Refer to the task/activity table shown here.Enter this information using MS Project to produce a Gantt chart - enable project summary. Assume that each resource has been assigned to the project activity on a full-time basis.

(a) Using the above information, produce a resource usage sheet identifying the total number of hours and daily commitments of each project team member. Record the total hours for each resource.

(b) Identify any members of the project team who have been overassigned.
(c) Determine and record the specific dates when there is a conflict in the resource assignment schedule.
(d) Using the information above, describe how you could level the resource load to remove conflicts? What is affected by the change? What assumptions are made?
3. Use the following information to construct a tracking Gantt chart using MS Project - enable project summary.

(a) What is the total % complete for the project overall?
(b) What is the Actual Duration for the project overall?
(c) What is the Remaining Duration for the project overall?
4. Assume you have collected the following data for your project. The roject budget is $90,000 and it is planned to last a total of 120 workdays. After collecting status partway through the project., you have collected the following status information,
PV = $100,000
EV = $80,000
AC = $65,500
| Schedule Performance Index(SPI) |
|
| Estimated Time to Completion |
|
| Cost Performance Index(CPI) |
|
| Estimated Cost to Completion |
|
Based on these values, estimate the time and budget necessary to complete the project.
(a) Describe how would you evaluate these findings? Are they good news or bad news?
(b) What could possibly cause this situation to occur? Be specific with examples.
