            1. Introduction 
          Software Development Life Cycle (in short SDLC) is a workflow 
          process which defines the core stages and activities of 
          development cycles. It can be used by system analysts, designers 
          and developers to plan and implement the applications and 
          deliver the systems or products on time and within budget. With 
          numerous of development methodologies, it is never an easy task 
          t o choose an appropriate strategy that sometimes even it is 
          i n e v i t a b l e   t o   m ix- and- m atch multiple methodologies to fit in a
