THE NEED FOR SYSTEM ANALYSIS
THE NEED FOR SYSTEM ANALYSIS
When you are asked to computerized a system, it is necessary to analyze the system from different angles. The analysis of the system is the basic necessity for efficient system design. The need for analysis stems from the following point of view:-
System objective: it is necessary to define the system objectives. Many times, it is observed that the systems are historically in operation and have lost their main purpose of achievement of the objectives. The users of the system and the personnel involved are not in a position to define the objectives. Since you are going to develop a computer-based system, it is necessary to redefine or reset the objectives as a reference point in the context of the current business requirement.
System boundaries: it is necessary to establish the system boundaries which would define the scope and the coverage of the system. This helps to short out and understand the functional boundaries in the system, and the people involved in the system. It also helps to identify the inputs and the outputs of the various subsystems, covering the entire system.
System importance: it is necessary to understand the importance of the system in the organization. This would help the designer to decide the design feature of the system. It would be possible then to position the system in relation to the other systems for deciding the design, strategy, and development.
Nature of the system: the analysis of the system will help the system designer to conclude whether the system is a closed type or an open, and a deterministic or a probabilistic. Such an understanding of the system is necessary prior to design the process to ensure the necessary design architecture.
Role of the system as an interface: the system, many times, acts as an interface to the other systems. It is necessary to understand the existing role of the system, as an interface, to safeguard the interests of the other systems. Any modification or changes made should not affect the functioning or the objectives of the other system.
Participation of the user: the strategic purpose of the analysis of the people to new development. System analysis process provides a sense of participation to the people. This helps in breaking the resistance to the new development and it also then ensures the commitment to the new development and it also then ensures the commitment to the new system.
Understanding of resource needs: the analysis of the system helps in defining the resource requirement in terms of hardware and software. Hence, if any additional resources are required, this would mean an investment from the point of view of return on such investment. If the return on such investment from the point of view of return on such an investment. If the return on the investment is not attractive, the management may drop the project.
Assessment of feasibility (practicability): the analysis of the system helps to establish the feasibility from different angles. The system should satisfy the technical economic and operational feasibility. Many a time, the systems are feasible from the technical and economic point of view, but they may be infeasible from the operational point of view. The assessment of feasibility will have the investment and the system designer’s time. It would also save the embracement to the system designer as he is viewed as the key figure in such a project.
