Chapter 19, Problem 11CQ
Consider two projects that have the same activities and the same dependencies. In the first project, the activity times are expected outcomes. The actual times will vary. In the second project, the activity times are always as expected. Assuming the expected activity times are identical across the two projects, which project will be completed first?
- a. The first
- b. The second
- c. Cannot be determined

Limbo Technologies has embarked on another project that has an estimated completion time of 40 weeks and a standard deviation of 5 weeks. It is estimated that the project completion time is normally distributed.
i)What is the probability of finishing the project in 38 weeks or less?
ii)The due date for the project is set so that there is a 90% chance that it will finish by this date. What is the due duration?

A project has a budget of $300,000 and is expected to last 10 months, with the work results and budget spread evenly across all months. The project just completed its 3rd month, the work is on schedule, and $65,000 has been spent. What is the cost variance? How efficient (in %) must work progress be to complete on time and within budget?
After the first month of a project, the Actual Cost was $400 and the planned cost for the first month was $500. Currently, only 50% of the work have been completed. Based on this information, calculate the following:
a.Earned Value
b.Cost Variance
c.Schedule Variance
