This document discusses several unified process frameworks for software development, including the Unified Process (UP), Rational Unified Process (RUP), Agile Unified Process (AUP), and Open Unified Process (OpenUP). The AUP combines agile approaches with a simplified RUP. It is iterative and scalable from small to large projects. OpenUP is an open source and agile process developed by the Eclipse Foundation that employs incremental development through micro-increments, iterations, and phases like inception, elaboration, construction, and transition.
