The spiral model
Hi Kelechi,
Wonderful post. The spiral model is almost the best. The spiral model enables gradual releases and refinement of a product through each phase of the spiral as well as the ability to build prototypes at each phase. The most important feature of the model is its ability to manage unknown risks after the project has commenced; creating a prototype makes this feasible. The spiral model is a great option for large, complex projects. The progressive nature of the model allows developers to break a big project into smaller pieces and tackle one feature at a time, ensuring nothing is missed. Furthermore, since the prototype building is done progressively, the cost estimation of the whole project can sometimes be easier.
