Sdlc spiral Model includes the iterative nature of the prototyping model and the linear nature of the waterfall model. This approach is ideal for developing software that is revealed in various versions.
In each iteration of the spiral approach, software development process follows the phase-wise linear approach. At the end of first iteration, the customer evaluates the software and provides the feedback. Based on the feedback, software development process enters into the next iteration and subsequently follows the linear approach to implement the feedback suggested by the customer. The process of iteration continues throughout the life of the software. [Read more...]
