"You need top focus on producing quality software, not on producing documentation...Many organizations that adopt the RUP product like it because it's complex, it describes a wide range of development roles, it's robust, and it describes how to create a wide range of artifacts. The problem is, in their exuberance, some development teams forget that their primary goal is to develop software that meets the needs of their project stakeholders and instead get lost in the documentation wilderness."
