System Analysis and Design

System design and system analysis are both important stages in the development of a software system, but they focus on different aspects of the process. System analysis is the process of studying and understanding the existing system and its requirements, including its functions, inputs, outputs, and user needs. System analysts work closely with stakeholders to gather and document requirements, create use cases, and develop models of the current system. System design, on the other hand, is the process of creating a new system or modifying an existing system to meet the requirements identified during the analysis stage. System designers use the requirements gathered during the analysis stage to create a detailed design of the new or modified system, including its architecture, components, and interfaces. In summary, system analysis is focused on understanding the existing system and its requirements, while system design is focused on creating a new system or modifying an existing system to meet those requirements. Both are important stages in the development of a software system, and they often overlap and inform one another. Effective system analysis and design can lead to the development of a high-quality software system that meets the needs of its users.
J. Duncan Glover has written: 'Software Manual for Power System Analysis and Design' 'Power System Analysis and Design'
The stages of system analysis are scope definition, problem analysis, requirements analysis, logical design and decision analysis. System analysis is defined as the study of sets of a system to find ways of improving its efficiency.
One example of a system and sub system in system analysis and design is an organization (system) with interrelated department (sub system). Another example would be a computer (system) and all of its components (subsystem).

In system analysis dfd is the primary step.it shows how the data flows from higher to lower level. which is very crucial to design. without this direct design can be a risky process.
