Earned value chart
At your upcoming status meeting with your project sponsor, rather than just using a table, you want to graphically show earned value. Which of the following charts will you use?
A. Trend analysis
B. Control chart
C. S-curve
D. Pareto diagram
Answer: C. S-curve
An S-curve graph typically displays earned value (EV), planned value (PV) and actual cost (AC). PV is charted first and will look like an S. As time progresses, the EV and AC will extend allowing you to compare them against the PV.
Three point estimate
While planning a project that has not been accomplished before at the company, your manager asks you to get a three point estimate from Shari, the lead designer. Shari provides you with an optimistic estimate (2 hours), a most likely estimate (4 hours), and a pessimistic estimate (12 hours). What must be the three point estimate for Shari’s task?
A. 5 hours
B. 6 hours
C. 10 hours
D. Not enough information and will need clarification from the manager
Answer: D. Not enough information and will need clarification from the manager
A three point estimate could be derived several ways. Two of the most common are the mean ((O+M+P)/3), which would give you 6 hours and PERT ((O+4M+P)/6), which would give you 5 hours. However, in this example, it is not clear what type of three point estimate to use.
Cost variance and schedule variance
If a project has a Cost Variance (CV) of 1000 and a Schedule Variance (SV) of -1000, what does it mean?
A. The project is under budget and behind schedule.
B. The project is over budget and ahead of schedule.
C. It is impossible to have a negative SV.
D. The Overall Variance (OV) is 0.
Answer: A. The project is under budget and behind schedule.
For both Cost Variance (CV) and Schedule Variance (SV), if the number is positive, then it is good. Conversely, if the number is negative, then it is bad. So CV of 1000 is good (under budget), while SV of -1000 is bad (behind schedule). There is no such thing as Overall Variance (OV).
Accelerated depreciation
Megan is working with her finance department to determine depreciation for a warehouse forklift that was purchased. She is told that accelerated depreciation will be used. If the forklift cost $50,000 and Megan wants to spread the depreciation over five years, which of the following will the first year most likely be?
A. $5,000
B. $8,000
C. $10,000
D. $15,000
Answer: D. $15,000
If Megan was asked to use straight line depreciation, then the answer would be $10,000, which is a simple average. For accelerated depreciation, the first year will be higher than the average and incrementally decrease over time. As a result, the first year depreciation could only be $15,000 from this list since it is the only value greater than $10,000.
