Abstract
In recent years, much has been written about how to present a compelling
business case. But, if just one critical piece of information is overlooked, it can lead to the
wrong decision being taken. This article aims to minimise the risk. It stems from research
conducted into how the business case can be used more effectively to improve the success rate
of information technology (IT) or information technology or business (ITB) projects. The
business case, usually a document, indicates whether the investment in money and resources
is justified, prior to or at any time during the project. ‘Effective use’ involves using certain
business case processes throughout the ITB project’s lifetime. Here, the life cycle refers only to
the IT component of the project. The lifetime is longer, extending from initial proposal until
all benefits have been realised. However, it is found that the processes are not easy to adhere
to, a probable cause being the lack of relevant information.
