This is based on the Treasury green book project guidance using the 5 case model. The Full Business Case (FBC) concentrates primarily on revisiting and updating the conclusions of the Outline Business Case (OBC) and documenting the outcomes of the procurement.
Part of: HM Treasury Green Book
The purpose of the Full Business Case (FBC) is to identify the marketplace opportunity that offers optimum Value for Money (VfM), set out the commercial and contractual arrangements for the negotiated deal, confirm the deal is still affordable and put in place the detailed management arrangements for the successful delivery, monitoring and evaluation of the scheme.
Much of the work involved in producing the FBC focuses on revisiting and updating the conclusions of the Outline Business Case (OBC) and documenting the outcomes of the procurement.
On completion of the FBC, a Gateway Review 3 (investment decision) should be considered for the project, prior to the formal submission of the FBC to the approving authority. All parties should now be content for the project to proceed to contract signature, providing the above work has been completed satisfactorily and the resultant scheme is affordable.
