MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -The spiral model, proposed by Barry Boehm in 1986, is such an evolutionary process aimed at rapid development of more complete versions of the software or system by taking into account the technical and managerial risks associated with each evolutionary level.

Detailed explanation-2: -The spiral model, initially proposed by Boehm, is an evolutionary software process model that couples the iterative feature of prototyping with the controlled and systematic aspects of the linear sequential model. It implements the potential for rapid development of new versions of the software.

Detailed explanation-3: -Definition: The spiral model is similar to the incremental development for a system, with more emphasis placed on risk analysis. The spiral model has four phases: Planning, Design, Construct and Evaluation. A software project repeatedly passes through these phases in iterations (called Spirals in this model).

Detailed explanation-4: -This Spiral model is a combination of iterative development process model and sequential linear development model i.e. the waterfall model with a very high emphasis on risk analysis.
