Structured Systems Analysis and Design Method (SSADM)
What is Structured Systems Analysis and Design Method (SSADM)
Structured Systems Analysis and Design Method (SSADM) is a systematic approach to the analysis and design of information systems. It is a model-driven method that emphasizes the importance of structured planning and the use of modeling techniques to represent the system and its requirements.
SSADM consists of a series of stages, including:
- Feasibility study: This stage involves evaluating the feasibility of the proposed system in terms of cost, time, and resources.
- Requirements definition: This stage involves gathering and documenting the requirements of the system, including the business processes, data, and user needs that the system must support.
- Logical design: This stage involves creating a logical model of the system, including a data model and a process model.
- Physical design: This stage involves creating a physical implementation of the system, including the hardware, software, and data structures required to support the system.
- Testing and implementation: This stage involves testing the system to ensure it meets the requirements and implementing the system in the production environment.
SSADM has been widely used in the development of information systems in a variety of industries and is known for its structured and systematic approach. However, it has been criticized for being inflexible and time-consuming and has been largely replaced by more agile methods in recent years.
