Author's Reply [to "Effectiveness" (Correspondance)]

Theauthor of the original article being commented on notes that "effectiveness" was not specifically defined in MIL-STD-721B because it is a term found in a dictionary. Only when associated with the word "system" was effectiveness defined specifically, in order to give the term a definite and a single meaning. The commentor's reference to Concept Formulation and Contract Definition procedures, now the basic and the most important part of weapon system procurement by all departments and agencies in DOD, is particularly significant. Importance of this subject to the private industry cannot be overemphasized.
