To improve business processes, Nissan
investigated production unit to improvethe efficiency of the energytransformation to the brake pad.
Based on success of Taguchisimplementation, Nissan's executivedecided that, they should apply Taguchis.
Using dynamic characteristics, Nissanimproves the efficiency of the energytransformation to the brake pad.
Overall weight of the brake system wasreduced and producing time was reduced
to 4% of the original time.Nissan technical centre conducts 70 projects
annually, all using dynamiccharacteristics.

Kodaks copy machine manufacturingdivision was faced with improvingthe reliability of its paper feeder
The Robust Design method provideddrastic improvement in the methodfor evaluating the failure rate
compared to the traditional way offeeding tens of thousands ofsheets, which was very expensiveand time consuming. Instead ofobserving the failures, the teamobserved the time needed for a
sheet of paper to reach a sensorafter the feed command is issued.

The arrival time is affected by the noise factors
such as weight of the paper, smoothness,
humidity, etc. If the arrival time is outside the
design window, it causes feeding failure. Thus,
a design that reduces the variation of the
arrival time causes fewer failures.
Measurement of arrival time needed newinstrumentation. But, the time for evaluating a
design reduced from weeks to about one hour.
Indeed, the Robust Design method uses a
measurement system focused on the main
function instead of measuring defects.
