System Analysis Phase
This is the second step of system development lifecycle. System requirement document is main deliverable for the systems analysis; it describes user requirement, cost and benefits and also concentrates on create alternative strategies. (Shelly & Rosenblatt, 2010)
?
System Design Phase
The design stage of the System Development Lifecycle focuses on the overall architecture of the IT system and detailed specifications for its various components (Pollard, Gupta, 2010, p.117). This stage creates the physical model which will settle with the documented requirement for the system.
