Deployment of system: Once the functional and non functional testing is done, the product is deployed in the customer environment or released into the market.
The Waterfall Model is the earliest method of structured system development. Although it has come under attack in recent years for being too rigid and unrealistic when it comes to quickly meeting customer's needs, the
