Why it is important SAD
system analysis and design
I need more about system analysis and design
all about the observation in our physical environment using the system analysis and design
It is important because improperly coded algorithms can crash the system or require geometric scaling resources.
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.

System Analysis and Design
Yes, it is important at all phases of development, not just systems development. Documentation is an important part of the discipline of Systems Analysis and Design.
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).
