The first step toward a successful project is to have full and clear understanding of why the project is being undertaken. This clear and commonality of understanding will be achieved through a Business Case.
Business cases can range from comprehensive and highly structured, as required by formal project management methodologies, to informal and brief – but regardless, they are essential. They facilitate the achievement of management commitment and approval for investment in business change including programmes and projects. A business case provides a framework for the planning and management of organisational change. The ongoing viability of the programme or project is monitored against the business case.
