Structured Systems Analysis and Design Method (SSADM) is a widely used approach for the analysis and design of information systems. It is a process-driven methodology that provides a systematic approach to the development of software systems. SSADM is based on a series of stages that are completed iteratively to produce a complete system design. The methodology involves five main stages that are completed in sequence: requirements analysis, logical design, physical design, implementation, and maintenance. Requirements analysis is the first stage of SSADM, and it involves gathering and classifying the requirements for the system. This stage is critical because it sets the foundation for the rest of the development process. During this stage, the designer works with the client to identify the objectives of the new system, analyze the current system, and create the requirements for the new system. Logical design is the second stage of SSADM. During this stage, the designer decomposes the problem into smaller sub-systems, identifies the relationships between the parts and overall system, and produces a conceptual model of the system. This stage is important because it helps the designer to understand the problem and develop a solution that meets the client's needs. Physical design is the third stage of SSADM. During this stage, the designer creates the actual design of the system, which includes hardware, software, database, and network design. This stage is important because it helps the designer to create a detailed plan for the implementation of the system. Implementation is the fourth stage of SSADM. During this stage, the system is built based on the design specification. This stage is important because it involves the actual construction of the system. Maintenance is the final stage of SSADM. During this stage, the system is regularly checked and updated to ensure that it continues to meet the client's needs. This stage is important because it helps to ensure the long-term success of the system. In summary, SSADM is a process-driven methodology that provides a systematic approach to the development of software systems. It involves five main stages that are completed in sequence: requirements analysis, logical design, physical design, implementation, and maintenance. SSADM is widely used because it helps to ensure that software systems are developed in a structured and efficient manner.

Structured Systems Analysis and Design Method (SSADM) is a process-driven design approach that consists of both the analysis and the design phases for developing a software system. It is a design methodology created in the 1980s that enables the designer to move from a project concept to a working system that meets the requirements of the client. It views the system design process as a series of steps that must be followed in sequence. The five main steps of SSADM are analysis, design, development, review and completion. During the analysis phase, the designer identifies the objectives of the new system, analyses the current system, and creates the requirements. During the design phase, the designer outlines the structure of the system, develops the data models, and details the system components. Development follows the design phase, where the actual programming is done based on the design specification. Once the development is complete, the system is reviewed and tested, and upon satisfaction, it is deployed.
