ABSTRACT
The system development life cycle (SDLC) is a set of steps that serves as the basis for most systems analysis and design methodologies. There is always a concern that the system developed may not accurately reflect the current business environment. The elapsed time between the initial proposal and system completion can be quite lengthy. The system development life cycle implies a phased approach, with complex tasks decomposed into smaller phases that are easier to achieve, control, and manage. The project management life cycle is similar to the system development life cycle, with stages or phases defining a schedule and triggering resource allocations. The basis for most systems analysis and design methodologies is the system development life cycle or SDLC. The objective of design is to determine how the problem will be solved. During design the analyst’s focus shifts from the logical to the physical.
