The development methodology of TIPL is based upon the industry standard Rational Unified Process. It provides inputs in the entire project workflows including requirements gathering, analysis, design, implementation, and testing. The documentation of analysis and design work would be done using Unified Modeling Language.

The software lifecycle is broken into cycles, each cycle working on a new generation of the product. The Rational Unified Process divides one development cycle in four consecutive phases. Each phase is concluded with a well-defined milestone—a point in time at which certain critical decisions must be made and therefore key goals must have been achieved. Inception phase: The business case for the system is established by identifying all external entities with which the system will interact (actors).. Elaboration phase: The problem domain is analyzed and a sound architectural foundation is established with a project plan. Construction phase: The components and application features are developed and integrated into the product and all features are thoroughly tested. Transition phase: During the transition phase the software product is handed over to user community. Each phase can be further broken down into iterations. An iteration is a complete development loop resulting in a release (internal or external) of an executable product, a subset of the final product under development, which grows incrementally from iteration to iteration to become the final system. Compared to the traditional waterfall process, the iterative process has the following advantages: Risks are mitigated earlier Change is more manageable Higher level of reuse The project team can learn along the way Better overall quality.
