For the XAN Insurance Company Web Project and considering the Agile Project Management approach, particularly the Dynamic Systems Development Method (DSDM) framework which emphasizes business value and active user involvement, the Business Case should justify the project in terms of cost, benefit, and risk.

Selected Statements for the Business Case:

D. The Sales Manager has calculated that the new coffee shop insurance product will increase revenues by 10% each week.

E. Market research shows that the number of coffee shop patrons taking legal action against retailers has increased by 200% over the past two years.

D. This statement provides a clear financial projection for the benefits of the project, which is a critical component of a Business Case. It quantifies the expected revenue increase, offering a tangible benefit to justify the project investment.

E. This statement outlines a market trend that necessitates the project, highlighting the increased demand for insurance due to rising legal actions against coffee shops. It underscores the relevance and timeliness of the project, adding to the justification for undertaking the project.

Why Other Statements Are Excluded:

A. While high-level functional and non-functional requirements are essential for project planning, they typically belong in project requirements documentation or the Project Brief, rather than the Business Case.

B. This statement provides market insight but does not directly justify the project from a cost-benefit-risk perspective. The relevance of selling Fairtrade products and alcohol to the insurance product project is tangential.

C. The request for a report on past sales provides background information but does not in itself justify the project investment. It might be used to inform the Business Case but is not a direct component of it.
