Concept: Contributions to the Business Scenario
Main Description

It is important to realize that the creation of a business scenario is not solely the province of the architect. As mentioned previously, business line management and other stakeholders in the enterprise are involved, to ensure that the business goals are accurately captured. In addition, depending on the relationship that an organization has with its IT vendors, the latter also may be involved, to ensure that the roles of technical solutions are also accurately captured, and to ensure communication with the vendors.

Typically, the involvement of the business management is greatest in the early stages, while the business problems are being explored and captured, while the involvement of the architect is greatest in the later stages, and when architectural solutions are being described. Similarly, if vendors are involved in the business scenario process, the involvement of the customer side (business management plus enterprise architects) is greatest in the early stages, while that of the vendors is greatest in the later stages, when the role of specific technical solutions is being explored and captured. This concept is illustrated in Figure 26-3.

Vendor IT architects might be able to assist enterprise IT architects with integration of the vendors' products into the enterprise architecture. This assistance most probably falls in the middle of the timeline in Figure 26-3.
