Requirements Analysis Phase All the documentation related to user requirement from the previous phase will be used in requirement analysis phase. In this phase all the project requirements will be discovered, analyzed, defined, and documented. This process includes measuring the process requirement, technical, and transitional requirements. According to Maryland’s Information Technology Department (doit.marylan.gov):“The purpose of the Requirements Analysis Phase is to transform the needs and high-level requirements specified in earlier phases into unambiguous (measurable and testable), traceable, complete, consistent, and stakeholder-approved requirements”. Enterprise architecture in this phase ensures that the project requirements provide enough bases for the project. In addition, the technologies that are used in the project should be consistent with enterprise architecture. Design Phase According to the National Institutes of Health: “The Design Phase seeks to develop detailed specifications that emphasize the physical solution to the end user's information technology needs. The system requirements and logical description of the entities, relationships, and attributes of the data that were documented during the Requirements Analysis Phase are further
Enterprise Architecture Enables Paper 5 refined and allocated into system and database design specifications that are organized in a way suitable for implementation within the constraints of a physical environment”. Enterprise architecture ensures that the system is well designed to improve business processes and also the new system is compatible with the target architecture of the enterprise. Development Phase This phase is known as system construction. A clear plan, complete design, and proper process is required in order to finish this phase successfully. The goal of the Development Phase is to transform the system design prototyped which was developed in the Design Phase into a functioning system that meet all documented system requirement. Enterprise architecture ensures that the new system remains compliant with the organization’s goals. In addition having the enterprise architecture helps to make sure that the new system does not negatively affect other systems in the organization.
