The project manager Sean Shawn employed the analogy with adjustment method to estimate the cost of constructing a three-car garage. Specifi cally, he started with the cost of an average two-car garage, $43,000, and increased it by 50 percent to

$64,500. Comment on the likely accuracy of the three-car garage estimate. Suggest a different approach that might yield a more accurate cost estimate, and then use this approach and made-up time and cost fi gures to compute the estimate.

Argue why your estimate is better than Sean’s. See Chapter 5, Figure 5.19, for Sean’s WBS.
