The '''spiral model''' is a risk-driven [[software development process]] model. Based on the unique risk patterns of a given project, the spiral model guides a team to adopt elements of one or more process models, such as [[Iterative and incremental development|incremental]], [[Waterfall model|waterfall]], or [[Software_prototyping#Evolutionary_prototyping|evolutionary prototyping]].
