The benefits of using quality assurance (QA) specifications can be lost if the specifications are poorly developed or improperly implemented. Ten steps must be followed in developing a QA specification. At each step, critical decisions affect the specification's effectiveness. Each of the steps and the factors that should be considered in making decisions are discussed. Particular emphasis is given to the handling of rejected lots and the development of pay adjustment schedules. The activities required for the successful implementation of QA specifications are also presented and emphasize the need for training of both agency and contractor personnel.
