Claim: RAD, which has advantages in traditional models of systems development that lends itself more to a structured environment, is the only methodology that has a long time frame according to Post, & Anderson 2006.
Evidence: The Radiation Assessment Detector (RAD) is an instrument mounted on the Mars Science Laboratory's Curiosity rover. Rapid-application development (RAD), also called rapid-application building (RAB), is both a general term for adaptive software development approaches, and the name for James Martin's method of rapid development. Researchers Alliance for Development (RAD) is a World Bank supported action-oriented and multidisciplinary network of researchers. Reflex anal dilation (RAD) is the reflexive dilation of the human anus to a diameter greater than two centimeters in response to the parting of the buttocks or anal stimulation, such as brushing with a medical instrument. In the field of ecology, the relative abundance distribution (RAD) or species abundance distribution describes the relationship between the number of species observed in a field study as a function of their observed abundance.
