2. To drill down into the various aspects of the business process without losing sight of the complete system.
Answer:
System Analysis:
System analysis can be defined simply as: “The study of business problem domain to recommend improvements and specify the business requirements for the solution.”
Or alternatively as:
“A problem solving technique that decomposes a system into its component pieces for the purpose of studying, how well those component parts work and interact to accomplish their purpose.”
Both the definitions highlight following important points:
• System analysis helps to create an understanding of the business processes, their linkage with one another, the parameters governing the data flow within the business, the controls and checks built into the processes and the reporting needs in a business where a problem exists or for which the software needs to be designed.
• System analysis creates the understanding and lays out the necessary relationships that will assist in defining a solution to the problem or the design of the proposed software that will meet the user needs.
These two points may be understood as providing a means for undertaking the following tasks:
• A technique to map the system under study.
• To drill down into the various aspects of the business process without losing sight of the complete system.
• To understand the Workability/Functionality of the subsystems and their role in achieving the objectives of the system as well as controls and checks in place.
• To establish the relationship or Level of interaction of each system with other components of the system.
