A business case is not simply a financial forecast of the hardware and software costs and the expected benefits. A business case for an information systems investment involves a comprehensive understanding of both the likely resources as well as the business drivers which will assist business managers improve their performance and thereby obtain a stream of benefits from the investment.In general there are approximately six steps in producing a business case for an information systems investment.1. Determine the high-level business outcomes that will be clearly and comprehensively expressed as a set of opportunities the organization can take advantage of, or problems that need to be rectified.2. Identify the corporate critical success factors that will be supported or enhanced by the operation of the completed information systems project or investment.3. Create a list of specific and detailed outcomes or benefits, their appropriate metrics, measuring methods and responsibility points that are represented by the stakeholders.4. Quantify the contribution made by the outcomes, which requires associating numbers or benefit values with outcomes where this is possible.5. Highlight the risks associated with the project.Fundamental to this new approach to developing a business case for information systems investment is the fact that it incorporates much more than the financial numbers which are typically found in the standard approach to a feasibility study. This approach looks behind the financial numbers to the improvements in business performance which are facilitated by information systems and which are the real drivers of the benefits. Furthermore, this approach to developing a business case allows the organization to manage the process so that the required results are achieved.
