RUP (Rational Unified Process)

Stands for "Rational Unified Process." RUP is a software development process from Rational, a division of IBM. It divides the development process into four distinct phases that each involve business modeling, analysis and design, implementation, testing, and deployment. The four phases are:


  1. Inception - The idea for the project is stated. The development team determines if the project is worth pursuing and what resources will be needed.



  2. Elaboration - The project's architecture and required resources are further evaluated. Developers consider possible applications of the software and costs associated with the development.



  3. Construction - The project is developed and completed. The software is designed, written, and tested.



  4. Transition - The software is released to the public. Final adjustments or updates are made based on feedback from end users.



The RUP development methodology provides a structured way for companies to envision create software programs. Since it provides a specific plan for each step of the development process, it helps prevent resources from being wasted and reduces unexpected development costs.
