MSTAR® and the IBM Rational Unified Process  (RUP®)

Mosaic’s Structured Testing and Assessment Repository (MSTAR®) is a proven testing methodology providing state-of-the-art testing processes.  The IBM Rational Unified Process (RUP®) is a comprehensive software development  methodology incorporating state-of-the-art development processes.  Much interest has been expressed on how these two powerful methodologies fit together.  This paper describes how MSTAR® complements and extends the power of RUP®.


RUP® places a high value on testing early and continuously to measure and provide feedback on the developed product’s quality.  RUP® includes a testing discipline that is responsible for iteratively performing the required testing. This discipline is supported by quality concepts and presents testing as a critical risk management technique. While the RUP® testing discipline represents a good iterative testing approach for software quality, it does not provide the depth of testing guidance needed to ensure that testing consistently meets its quality objectives across all projects.

MSTAR® shares RUP®’s vision of early and continuous testing and is supported by similar quality concepts. MSTAR® encompasses industry-recognized testing activities based on years of experience focused on developing testing expertise. With this expertise, MSTAR® offers a depth of guidance, best practices and support that transforms RUP®’s testing discipline into a comprehensive, consistent and highly effective risk management tool. The following table summarizes the testing support provided by RUP® and MSTAR® for the key testing activities. This table reflects RUP®’s most current testing discipline.

As illustrated in the previous table, MSTAR® and RUP® support the same quality testing workflow, but MSTAR® completes and extends the RUP® process with comprehensive guidelines, templates and samples based on industry testing experience.
