The purpose of this competency is to achieve the goals of business case management, i.e. to:
- summarise context and delivery in a single document;
- explain the desirability, achievability and viability of the proposed work;
- develop the primary document that will be used to support a ‘go/no go’ decision at all gates in the life cycle;
- update and maintain the business case throughout the life cycle.
You must be able to:
- perform high level planning (to develop an outline business case)
- summarise the output of detailed delivery documents (to develop a detailed business case)
- use appropriate techniques to justify the project or programme
- prepare and present the business case in a way that is likely to gain the support of stakeholders
- develop arguments that justify the project or programme to stakeholders
- respond to requests for additional information in a clear and timely way
- monitor factors that influence the viability of the business case
- assure the quality of the business case
Since the business case is primarily a summary and presentation of more detailed information, the difference between a simple and a complex context is covered by adaptations of the competences that create the detailed information.
This competency can be interpreted for all levels of complexity without any significant adjustment.
In owning the business case, the sponsor is accountable for all these performance criteria but may be more actively involved in areas such as P5 and P7.
