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.
