ABSTRACT
Some of the general level requirements to be fulfilled may be known, the systems that must communicate or establish interfaces may be identified, and generic business processes may be specified. A systems development project plan should also always have a strategic business orientation, rather than just a technological perspective. The identification and evaluation of alternative solutions should be repeated for each of the improvement opportunities on every project that is contemplated within the information technology environment. The business case is an instrument that is used in project management to show the value to be returned from the selected project. The cost–benefit analysis, in many instances, is the primary component of a business case done at this early planning stage. In the planning of systems for business, their relationship with the global business model and the scope and performance of the technology architecture that supports it should be known.
