“…The concept of guardbands represents the methods to tackle the inaccuracy of a measurement system by tightening the acceptance limits in order to secure product quality seen by customers, while attempting to minimise the quality costs. There are numerous studies on guardbands and how to specify them optimally [1][2][3][4][5]. These studies, however, examine guardbands from the viewpoint of quality assurance, where the special emphasis is not on minimising the quality costs.…”

“…Specification limits describe requirements for products, while acceptance limits are the actual decisive factors in manufacturing. Conventional approach has been tightening the acceptance limits, in order to assure quality [1][2][3][4]. This study analyses whether it is worthwhile from the business perspective to consider the opposite, and widen the acceptance limits.…”

In modern electronics, specifications for products have constantly been tightened due to performance competition. The processes for product development and manufacturing have been developed to meet the tighter specifications and quality requirements. The development of test methods and measurement devices have not been as fast, and as a consequence, the relative impact of measurement errors has increased. Traditionally, the measurement inaccuracies have been compensated by tightening the acceptance limits. This study concentrates on analysing, through simulation, how companies should minimise the failure costs by adjusting acceptance limits. The study shows, in contrast to the conventional thinking, that widening the acceptance limits makes business sense in some cases.

“…Without aiming at completeness, we briefly indicate two possible variations. Suppose, we now have (Xn, Y,) i = 1 ..... m and )(2, i = 1 ..... n, where m>~n. Hence, replications are available for a subsample only (see Albers et al, 1994b for a related scheme). Denote Xil by Xi.…”
