SSADM

SSADM stands for Structured Systems Analysis and Design Method. It is a systems development methodology widely used in the United Kingdom. SSADM provides a systematic approach to analyzing and designing information systems. It breaks down the development process into distinct stages, each with its own set of tasks and deliverables. The method emphasizes the use of structured techniques, such as data flow diagrams and entity-relationship diagrams, to model the system.

The core principles of SSADM include a focus on requirements, a step-by-step approach, and the involvement of users throughout the development lifecycle. It aims to produce well-documented and maintainable systems. SSADM is particularly well-suited for large, complex projects where a clear and controlled development process is essential.

The method is typically divided into several main stages: feasibility study, system investigation, system options, and system specification. Within these, there are further steps such as requirements analysis, logical design, and physical design. The deliverables from each stage are designed to provide clear documentation for the next phase of development. While SSADM has been influential, its adoption has varied, and newer methodologies have emerged.
