The Rational Unified Process model is built on three fundamental entities: roles, activities, and artifacts.
Disciplines are natural groupings of process activities, roles, and artifacts.
Workflows relate activities, artifacts, and roles in sequences that produce valuable results.
Guidelines, templates, and tool mentors complement the description of the process by providing detailed guidance to the practitioner.
The Rational Unified Process is an open process framework based on an industry standard called SPEM.
