The Incremental Model The downside to this approach is that it can be more costly to develop and release multiple versions of the product. Compatibility issues with earlier version of the product. There is a variation of the incremental model, named the iterative and incremental development model (IIDM). 20 RNB Global University, Bikaner. Course Code - 13004500

The Spiral Model The Spiral model has introduced in 1980 by Barry Boehm. It introduced to analyze Risk in software development, which other models where not considered. According to this model, the process of developing a system consists of a series of cycles or iterations. Each cycle begins with the identification of objectives and requirements of the current stage, as well as an analysis of alternatives and constraints. 21 RNB Global University, Bikaner.

The Spiral Model This process will highlight areas of uncertainty (risk), which will be taken into account during the next step. This process involves constant improvement of the prototype as risks are decreased. 23 RNB Global University, Bikaner. Course Code - 13004500
