Information on Spiral Development Model

The spiral development model is a lifecycle model that is an iterative process for the development of a system specification, either as a complete specification, or as a specification of an increment within an evolutionary acquisition model. A simple view of the spiral development model would see developers move through a spiral of requirements elicitation/generation, requirements analysis and negotiation, requirements documentation and requirements validation until they were sure that they had an adequate representation of the functional architecture and could produce a System Specification. The spiral development model would then continue through each of the levels of design within the Acquisition Phase.
