A business case is an opportunity

All governments seek to optimise the success of their investment in digital transformation and ICT infrastructure.

A business case is a formal framework used to explain to the need to start an initiative. It gives decision-makers a clear understanding of the problem to be solved and offers practical solutions.

The business case explains to decision-makers the purpose, risks, and intent of a proposed ICT investment. It should give the decision-makers confidence that the recommended solution has undergone rigorous analysis and that it is the best option to achieve your objectives and intended outcomes.

Remember that your organisation may have specific requirements on the format of the business case, depending on the size of the investment and the implementation risks of your proposal.
