[CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]


Ends with the delivery of the software product


Is more chaotic than the incremental model


Includes project risks evaluation during each iteration


All of the above

Detailed explanation1: 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 explanation2: 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. It allows incremental releases of the product or incremental refinement through each iteration around the spiral.
Detailed explanation3: Which statement is true about the Spiral model? It is a hybrid approach that uses both Waterfall and iterative approaches.
Detailed explanation4: 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.
Detailed explanation5: It is based on the assumption that the development of applications is an iterative cycle that is repeated until the set goal is reached. The spiral model minimises the risk of failure in large software projects considerably by regularly assessing risks and checking the intermediate product on a regular basis.
