the most important feature of spiral model is

This blog will discuss this prodigious and widely used SDL model in detail. The most important feature of spiral model is (A) requirement analysis. (A) Data coupling. (D) configuration management. For smaller projects, the Agile concept is more appropriate. The major distinguishing feature of the spiral model is that it creates a risk-driven approach to the software process rather than a primar- ily document-driven or code-driven pro- cess. A Spiral Model of Software Development and Enhancement Barry W. Boehm, TRW Defense Systems Group “Stop the life cycle-I want to get off!’’ “Life-cycle Concept Considered Harmful.
