When establishing a methodology for business cases, it would be MOST beneficial for an enterprise to include procedures for:

Including procedures for updating the business case throughout its life cycle ensures that the document remains a living artifact, reflecting changes in project scope, costs, benefits, and strategic alignment. This continuous updating allows for informed decision-making at various stages of the project, ensuring ongoing relevance and value realization.

Addressing changes outside the business case refers to managing broader organizational changes, which is important but distinct from maintaining the integrity and relevance of the business case itself.
