Again, as with sales engineers successful quality-control proponents do not blame their failure upon the prospect when they do not make a sale. Instead, they try to analyze that part of their approach which failed to make a satisfactory impression. Perhaps the costs quoted for the program were unduly or unrealistically high; perhaps there was excessive emphasis upon the organizational and administrative aspects of quality control; perhaps there was too little emphasis upon the benefits to be gained from application of quality-control technology. If the fault was in the approach used, the quality-control proponents try to improve their approach; if the fault was in the form of the quality- control program proposed, thy will rework the program, if deemed necessary, so that its undesirable features will be eliminated.
