Assignment Help:

System Development Life Cycle (SDLC) stages are sometimes known as System Study. System concepts which are important in developing business information systems expedite problem solving and improve the quality of decision-making. The system analyst has to do a lot in this connection. They are confronted with the challenging task of creating new systems and planning major changes in the organization. The system analyst gives a systems development project, meaning and direction. However, the typical breakdown of an information systems development life cycle includes a feasibility study, requirements collection and analysis, system design, prototyping, system implementation, validation, testing and operation.

(a) (i) From the above statement, what is meant by Feasibility Study of a system?

(ii) Describe any four types of Feasibility Study.

(b) (i) What do you understand by the term Prototyping and explain any two ways of Prototyping.

(ii) Prototyping concept can be of great importance as well as can represent failures if not handle in an efficient way. List the possible benefits and limitations of this concept.

(c) In the System Implementation phased, there are four main conversion strategies that can be adopted or implemented. Conversion is the process of changing from old system to a new system.

(i) Explain the four ways or types of conversion.

(ii) Give one advantage and one disadvantage for each type of conversion you describe.
