► For Large (but scalable) projects, RAD requires sufficient resources to create the right number of RAD teams.

► RAD projects will fail if there is no commitment by the developers or the clients to ‘rapid-fire’ activities necessary to get a system complete in a much abbreviated time frame.

► If a system cannot be properly modularized, building components for RAD will be problematic

► RAD is not appropriate when technical risks are high, e.g. this occurs when a new application makes heavy use of new technology.
