If they becomes infeasible for the organization.2. Problem investigator– The analyst studies the problems and needs of the organization during feasibility and requirements andanalysis phases of SDLC. He visits various departments of the organization and interviews the users. He analysis the problems of thecurrent system and collects their new requirements.3. Problem solver– The analyst solves the problems of the current system faced by the users. He determines how people, methodand technology can improve the current system.4.System designer– The analyst creates a detailed physical and logical design of the system. So as to find out the requirements of thenew system.5.Motivator– The analyst motivates users to participate in development and implementation of the proposed system. This helps tounderstand user’s needs. He appeals management and users for getting the support in development and implementation of theproposed system.
6.Project managerThe analyst monitors the development and implementation of software in relation to quality, cost and time. Heworks with the project leader for managing the project properly.
SystemStakeholdersSYSTEM LIFE CYCLESystem life cycle is an organizational process of developing and maintaining systems. It helps in establishing asystem project plan, because it gives overall list of processes and subrocesses required for developing a system.System development life cycle means combination of various activities. In other words we can say that variousactivities put together are referred as system development life cycle. In the System Analysis and Designterminology, the system development life cycle also means software development life cycle.Following are the different phases of system development life cycle:1)Preliminary study2)Feasibility study3)Detailed system study4)System analysis5)System design
6) Coding7) Testing8) Implementation9) Maintenance(a) Preliminary System StudyPreliminary system study is the first stage of system development life cycle. This is a brief investigation of thesystem under consideration and gives a clear picture of what actually the physical system is?.
In practice, the initial system study involves the preparation of a ‘System Proposal’ which lists the ProblemDefinition, Objectives of the Study, Terms of reference for Study, Constraints, Expected benefits of the newsystem, etc. in the light of the user requirements.In summary, we would say that system study phase passes through the following steps:i.problem identification and project initiationii.background analysisiii.inference or findings (system proposal)(b) Feasibility StudyIn case the system proposal is acceptable to the management, thenext phase is to examine the feasibility of thesystem. The feasibility study is basically the test of the proposed system in the light of its workability, meetinguser’s requirements, effective use of resources and of course, the cost effectiveness.
