EV questions
Submitted by cnppmp on Mon, 05/20/2013 - 16:37
Q1) A task was scheduled to use two persons, full time, and take two weeks to complete. Instead, the project manager was only able to assign one person to this task. At the end of two weeks, the person assigned to the task completed 75% of the work.
What is the cost performance index?
Q2) A Project was scheduled to be performed by four resources for three weeks, working throughout the Project duration. During first week, only two resources were assigned, whereas during second week, four more resources joined in. At the end of second week, 40% of the value of the work had been completed.
What is the CPI for this Project at the end of second week?
Options are not available, but mehtod is important.

We don't have any actual cost info
Q1) & Q2) We don't have any actual cost information here (since CPI = EV / AC)... The given data seems more for SPI = 0.75 and 0.4 respectively?
In any case, we shouldn't be concerned with who or how many people did what, only the final value added or work complete should matter for computing indices. Right?

how did you arrive at SPI as
how did you arrive at SPI as 0.75 & 0.40,
75% is considered as EV right and PV should be planned completion for 2 week.
also, for the second one 0.4?

Because the numbers are given
Because the numbers are given as percentages (and not as absolute values) in the question.

Question 1 : CPI 1.5 Question 2 : CPI 0.8
Question 1 : CPI 1.5
Total Work Done EV = 0.75
AC = 0.5 [ As BAC was 2 Resouce 2 Weeks i.e 4 person Week But Used only 2 Person Week ]
So CPI = 0.75/0.5 = 1.15
Question 2 : CPI 0.8
Total Work Done 0.40 EV
Actual Cost 6 Person week [ As BAC was 4 Resouce 3 Weeks =12 Week ] So AC = 0.5
So CPI = 0.4/0.5 = 0.8
