Question

What will be an ideal response?

Answer 1

The purpose of systems analysis is to ensure that the information systems being built have the right goals and requirements, are appropriate to the business in terms of the business goals, capabilities and needs, and to make sure that the implementation process will be successful. Systems analysis consists of three general steps: (1 ) define and understand the problem, (2 ) identify alternate solutions, and (3 ) choose the best solution. In defining the problem, systems analysts typically gather facts about existing systems and problems by examining documents, work papers, procedures, and system operations and by interviewing key users of the system, and identifying system requirements. In developing alternate solutions, systems analysis lays out the most likely paths to follow, given the nature of the problem. Some possible solutions do not require an information system solution, but instead call for an adjustment in management, additional training, or refinement of existing organizational procedures. Some, however, do require modifications to the firm's existing information systems or an entirely new information system. In choosing a solution, systems analysis includes a feasibility study to determine whether each proposed solution is feasible, or achievable, from a financial, technical, and organizational standpoint. The feasibility study establishes whether each alternative solution is a good investment, whether the technology needed for the system is available and can be handled by the firm's information systems staff, and whether the organization is capable of accommodating the changes introduced by the system. A written systems proposal report describes the costs and benefits, and advantages and disadvantages of each alternative solution. The systems analysis will detail the costs and benefits of each alternative and the changes that the organization will have to make to use the solution effectively.
