The form and depth of analysis required for this work product depends on the level of investment required for the
project. The requirement for high levels of investment will demand a very formal, well researched and well founded
Business Case. The greater the amount of investment, the more estimates will be challenged by senior management.
In the case of a project performed under contract (as a result of a bid award, for example), the Request for Proposal,
the response, and the subsequent contract together form the Business Case.
