A view of the world that may or may not conflict with accepted scientific principles. -- adapted from (Vaughn 1997, p. 196)

Although the standard definition of paradigm is simply example, the word has come to mean in Vaughn's sense a way of thinking that may be positive or negative with respect to the Culture involved in the development and operation of a system, such as the Challenger. In a positive sense paradigm can mean the way of thinking about the systems engineering methodology itself.
