FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Systems analysis means understanding and specifying in detail what the information system should accomplish. Systems design means specifying in detail how the many components of the information system should be physically implemented.

Detailed explanation-2: -System Design – it is a process of planning a new business system or replacing an existing one. It is also specifying in detail how the parts of an information system should be implemented. It implies a systematic and rigorous approach to design-an approach demanded by the scale and complexity of many systems problems.

Detailed explanation-3: -System analysis refers to the process of gathering data, interpreting information, identifying issues and using the results to recommend or develop possible system improvements. During this stage, companies may also evaluate future business needs and how improvements may answer them.

Detailed explanation-4: -Identify the deficiencies of current system and set goals. Enumerate the alternative solution or potential candidate system to meet goals. Determine the feasibility of each alternative such as technical feasibility, operational feasibility, etc. Weight the performance and cost effectiveness of each candidate system.

Detailed explanation-5: -Systems analysis is the process by which an individual (s) studies a system such that an information system can be analyzed, modeled, and a logical alternative can be chosen. Systems analysis projects are initiated for three reasons: problems, opportunities, and directives.
