one of the major controversies in project management occurs over whether the project manager needs a command of technology in order to be effective. Consider the following situation:You are the project manager on a research and development project. Marketing informs you that they have found a customer for your product and that you must make major modifications to satisfy the customer’s requirements. The engineering functional managers tell you that these modifications are impossible.

a) Can a project manager without a command of technology make a viable decision as to whether to risk additional funds and support marketing, or should he believe the functionalmanager, and tell marketing that the modifications are impossible?

b) How can a project manager, either with or without a command of technology, tell whether the functional managers are giving him an optimistic or a pessimistic opinion?
