Techopedia explains Rational Unified Process (RUP)

RUP has enabled great strides in development community standards and the acceptance of use cases and unified modeling language (UML). RUP is comprised of three characteristics and a recurring four-phase cycle.

RUP has the following key characteristics:

  • Use-case driven from inception to deployment
  • Architecture-centric, where architecture is a function of user needs
  • Iterative and incremental, where large projects are divided into smaller projects

RUP follows the following four-phase process:

  • Inception: The core idea is envisioned.
  • Elaboration: Use cases and architecture are designed.
  • Construction: Activities from design to completed product
  • Transition: Follow-up activities to ensure customer satisfaction
