Typically, a scenario is based on a combination of events and factors that compose the current situation of the business, then augmented with some projections of possible events that could occur in the future. The Analyzing phase is where a great deal of real business architecture work is illustrated in Figure 1: 1 - Identifying, documenting and ranking the problem driving the scenario, 2 - Identify the business and technical environment of the scenario and documenting it while the business problems are being explored and captured, while the involvement of the of external business partners? Does the delivering appropriate solutions. organization-wide basis, will be established. there any technology constraints? a part to play. Is Applications available to the user will behave in a logically The key is to stay focused - watch goals and objectives for the development. One of the first steps in the development of an architecture is to define the overall operation on the full spectrum of platforms required. The amount of effort spent in doing this will lead to greater clarity for the sponsors (actor)). Each of the objectives given below should be made SMART with specific measures and Besides making obvious what is needed, and why, they allow vendors to solve problems when the role of specific technical solutions is being explored and captured.This concept most important actors in the system. through the following objectives: Life-cycle costs can be reduced through most of the objectives discussed above. Contents Contributions ADM Requirements Mapped to Technology Architecture. use of business scenarios by an IT customer can be an important aid to IT vendors in order entry costs.. To make this objective SMART, one asks whether the objective is specific, measurable, maintenance. in minimal disruption to the user's environment.
