What a great phrase to start a debate around the board table, often heated, as most still see the two as a trade-off, the better the quality, the higher the cost.
How much better to beat the bean counters at their own game by quantifying it:
Quality cost = the number produced outside specification X the total cost of rework & disposal.
Simple. The cost of quality calculated, and how often will you find any added short term cost during production will be dwarfed by the costs of managing the out of spec production.
