Q2 Explain various phases of a Software Development Life Cycle.   (5 marks)

SOFTWARE ENGINEERING PHASES

The life cycle of a computer-based system exhibits the following distinct phases.

The life cycle methodology for developing complex systems is modular and is a top down procedure. In the study phases. modules that describe the major functions to be performed by the system are developed The procedure is called top-down because in successive phases the major modules are expanded into additional, increasingly detailed modules. Powerful graphic tools have been developed to structure the top - down design and development phase activities in detail. For present. we can summarize the principal tasks associated with each of the phases of Iife cycle of a computer-based business system.

This is the phase during which a problem is identified alternate system solutions and studied and recommendations are made about committing she resources required to design the system. Tasks performed in the study phase are grossly analogous to (1) determining that a shelter from the elements is needed, and (2) deciding that a to z bedroom house is more appropriate shelter than a palace, a cave, or other possible selections.
