Q:

Iam looking to estimate the cost on a project, but I don't want to spend a lot of time on a detailed analysis. I really want a ballpark figure. What options do I have?

A) None - Cost estimating requires details to be accurate	B) Use the cost of similar projects
C) Use a rule-of-thumb or per-square-foot estimate	D) Add up the costs on the WBS

Answer & Explanation Answer: B) Use the cost of similar projects

Explanation:

Although it is less accurate than adding up individual costs from the WBS, it is less time consuming. The trade-off is accuracy. Answer A is incorrect because to do a more accurate cost estimate, you need to delve into details. Answer C is tempting also, and possible, except we don't really know if the project in question can use perametric modeling . Answer D is incorrect because it takes the most time, but it is most accurate.
