1-19 Update Business Justification

A preliminary business justification was developed in Section 1-4, Prepare Preliminary Business Justification for the Need. It is updated during the Conduct Make vs. Buy Decision Analysis task. This phase focuses on assessing whether the preliminary business justification was realistic. The updated business justification should be accurate and complete and must provide all the information required for senior management to make an informed investment decision.

The aims of updating a business justification are to:

• Establish that the preferred option (make vs. buy) meets the business need.
• Justify the need for investment.
• Produce an effective supplying strategy.
• Demonstrate that the preferred solution represents value.
• Confirm that the planned investment is affordable.

When updating a business justification, it is necessary to build on the factors of strategic fit, achievability, affordability, business options, and commercial availability.
