System design vs system analysis

Answer 1

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.

Answer 2

Analysis is detail design. Design in general is to abstract the concept at a higher level.

System Design defines the system you try to build and help you to break down that system into smaller and manageable pieces to do the system analysis.

You define your system as: Input, Core functions, Output (no specific for each part, this is the design). When you define Input, how to get the input data, action, etc., you may still in design mode, but from the overall point of view, you are doing the analysis.
