On friday afternoon at the end of the fourth month half way

Question

You are managing an eight-month project with a BAC of $100K. On Friday afternoon, at the end of the fourth month (half way through the project), your EVM system provides the following values:

BCWP = $50K ACWP = $75K

and your boss asks you to present the EAC at the Monday morning status meeting. You have been an attentive project manager and you have been especially pleased that the BCWP has been tracking quite well to the BCWS. Below are listed three possible answers one might provide as the EAC. 

For each possible answer, first list any assumption(s) necessary regarding future performance and then provide the rationale which would justify or explain it.

• $100K: 
• $125K: 
• $150K: 

Having done the analysis and considered the explanations for each of these answers, which answer would you be most comfortable presenting to your boss?  Why?
