Quality, cost, delivery
Also called: qcd, quality, money, time or devil's triangle
Quality, cost, delivery (QCD) is a term derived fromlean manufacturing, creating as much value for the customer as efficiently as possible. In practice, this usually results in a compromise between quality, cost and time.
This is also known as the devil's triangle. Many customers desire a perfect product at a low price that can be delivered quickly. However, the mutual effects between these factors make this optimal combination virtually impossible. For example, a low price will come at the expense of quality or cause a product to be delivered later. Need for very high quality will in turn drive up the price and delivery time.
The compromise between quality, money and time usually consists of the most appropriate balance between the three aspects, or an emphatic choice of one or two of them.
