Spiral Increment Reuse (SIR) Software Model

The success or failure of any project is very largely depends on its SDLC (Software Development Life Cycle) model. In this paper a new software development lifecycle model is designed using incremental spiral lifecycle model with software reuse concept. The proposed model is designed in such a way that it combines the capability of spiral and incremental model with reusability. The software development process starts with the requirement analysis and identification of required components with the help of SRS followed by component design. Required component are identified from RCL (Reuse Component Library). The components are modified according the requirement and if components are not available, they are rapidly developed and after testing it is stored in TCR (Tested Component Repository). This SDLC model will increase the quality and productivity of project, delivered in shorter tenure and in lower cost.
