However over time, Rational (and subsequently IBM Rational) added additional guidance and artifacts to extend the applicability of RUP to all sorts of situations, such as package implementation, maintenance projects, technology specific guidance (J2EE, .Net etc.), systems engineering and may other project types. In practice RUP suffered from several problems:

Yes, RUP properly applied in the right circumstances can be very effective. Unfortunately though, that often did not happen in practice.
