Q. Realistic approach to the development of large-scale systems?

There are a number of advantages of Spiral model that makes it a realistic approach to development of large-scale systems and software viz

1) The spiral model promotes excellence assurance through prototyping at every stage in system development.

2) The spiral model is a sensible approach to the development of large-scale software products for the reason that the software evolves as the process progresses. The developer as well as client better understand and react to risk at all evolutionary level.

3) The model utilizes prototyping as a risk reduction mechanism as well as allows for the development of prototypes at any phase of the evolutionary development.

4) It maintains a systematic step-by-step approach like the classic life cycle model however incorporates it into an iterative framework that additional reflect the real world. If employed accurately this model should reduce risk prior to they become problematic as consideration of technical risk are considered at every stages.
