Detailed explanation-1: -1. Preliminary System Study: As the name says it is the first stage of a system development life cycle, a brief investigation of the system under consideration and gives a clear picture of what actually the physical system is?

Detailed explanation-2: -Phase 1 of the systems development life cycle involves a preliminary analysis, an initial phase at the start of a project that determines whether the concept is viable; any proposed alternative solutions; the cost benefit evaluation; and finally the submission of the preliminary plan for recommendations.

Detailed explanation-3: -Preliminary study The initial system study involves the preparation of a system proposal which list the problem definition, objectives of the study, terms and reference of study, constraints, and the expected benefits of the new system, etc.

Detailed explanation-4: -The main objectives of preliminary analysis is to identify the customer’s needs, evaluate system concept for feasibility, perform economic and technical analysis, perform cost benefit analysis and create system definition that forms the foundation for all subsequent engineering works.
