Lori is the newly appointed project manager for the Fultz Metal Works Company, a small $30 million tool-and-die manufacturer. To remain competitive, the company is launching a series of projects to upgrade all of its computer-aided machinery. The project will be costly and risky for Fultz Metal.

If you were offering advice to Lori on the selection of a methodology, what would you say and why?
