Enterprise analysis provides many things for an organization.

 Solution performance assessment is not a task included in enterprise analysis, but rather in solution evaluation. Enterprise analysis focuses on identifying and defining the business need, assessing the capability gaps, determining the solution approach, defining the solution scope, and defining the business case. These tasks help the organization to align its strategic goals and objectives with the proposed initiatives and solutions. References:
