In the technical requirements phase, you start with the business requirements and business constraints defined during the business analysis phase and translate them into technical specifications that can be used to design the deployment architecture. The technical specifications measure quality of service features, such as performance, availability, security, and others.
During the technical requirements phase you prepare the following information:
Analysis of user tasks and usage patterns
Use cases that model user interaction with the planned deployment
Quality of service requirements derived from the business requirements, taking into consideration the analysis of user tasks and usage patterns
The resulting set of usage analysis, use cases, and system requirements documents are inputs to the logical design phase of the Solution Life Cycle. During technical requirements analysis, you might also specify service level requirements, which are the terms under which customer support must be provided to remedy a deployed system failure to meet system requirements. Service level requirements are the basis for service level agreements signed during project approval.
