Main Description

Business scenarios help address one of the most common issues facing IT executives: aligning IT with the business.

The success of any major IT project is measured by the extent to which it is linked to business requirements, and demonstrably supports and enables the enterprise to achieve its business objectives. Business scenarios are an important technique that may be used at various stages of defining enterprise architecture, or any other major IT project, to derive the characteristics of the architecture directly from the high-level requirements of the business. Business scenarios are used to help identify and understand business needs, and thereby to derive the business requirements that the architecture development, and ultimately the IT, has to address.

However, it is important to remember that business scenarios are just a tool, not the objective. They are a part of, and enable, the larger process of architecture development. The architect should use them, but not get lost in them. The key is to stay focused - watch out for "feature creep", and address the most important issues that tend to return the greatest value.
