Solution components are the parts of the physical architecture that implement the solution requirements. They include business processes, business policies, business rules, software applications, hardware devices, data structures, and other elements that constitute the solution. Solution components are identified and defined during the design process, and they are allocated to the requirements during the allocate requirements process. The purpose of allocating requirements to solution components is to ensure that each requirement is fulfilled by one or more solution components, and that each solution component contributes to one or more requirements123.
Assessment of proposed solution is not a solution component, but a technique that evaluates the feasibility, desirability, and suitability of a solution option. Assessment of proposed solution is used during the enterprise analysis process, which involves defining the business need, assessing the capability gaps, determining the solution approach, defining the solution scope, and defining the business case. The purpose of assessing the proposed solution is to compare the expected benefits and costs of the solution option, and to identify the risks, assumptions, and dependencies that may affect the solution delivery456.
