Difference between agile and waterfall approaches | APM Waterfall is the standard methodology that involves a linear process of developing a project that starts at conception and progresses through Tends to yield higher customer satisfaction since frequent feedback leads to increased prioritization of customer needs. Waterfall The most basic difference between the waterfall model and the RAD model is that the waterfall model is a linearly-sequential life cycle model of software development in which software testing is done after the completion of all coding phases. Agile uses an incremental methodology, whereas the design process is sequential in the waterfall methodology. One logic is called the bureaucratic model.
