Case study An automatic document handler(adh) was developed at the ss level. When integrated into the total system there were many new problems. The TQM Problem Solving Process was used, and many problems were solved. however. at the Field readiness Test (frt) before entering production the reliability was 15X worse than acceptable Fig. 2 C Don Clausing 1998
