Developing software is far from an exact science and without a structured system to guide the process a project is likely to fail. Defining and adhering to a Software Development Life Cycle (SDLC) early in the project will help to guide the development of a new information system. In addition to having the structure for the development team to work within a defined and agree upon SDLC will help to set the proper expectations for deliverables with the stakeholders and customer(s).

feedback, respect and courage (Wells). An XP programmer requires maintaining communication with customers and colleague, and sustaining their design simple and clean (Wells). Programmers are to get feedback by testing the software, and delivering end system product to the customers as early s possible (Wells). Lastly, programmers respect their colleagues as they, together, courageously respond to the changing and evolving technology (Wells). In addition, XP has its own twelve simple rules these rules

google search, google maps etc. The project is developed based on the following software development cycle. It starts with collecting the requirements and ends with the deployment phase with many phases in between. The phases in the software development plan are Requirements Specification, planning and Design, code Implementation, Testing, Deployment and Maintenance.Usually in the software development life cycle we have considered after each and every phase if the requirements are not satisfied or

economic priorities • Users are unsure of their needs • Requirements are complex • New product line Incrimental model The incremental build model is a method of software development where the model is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance. The product is defined as finished when it satisfies all of its requirements. This model combines the elements of the waterfall model with the iterative
