What Does It Achieve? What Does It Mean? But the definition for zero defects is not so clear.

Perhaps zero defects refers to the domain beyond 3. There is value in trying to understand the meaning and purpose of this oft-used term, and whether its use is the best approach in a Six Sigma environment of continuous improvement. Edwards Deming believed that slogans and programs such as zero defects are usually counterproductive.

But can a mere slogan actually discourage the successful implementation of proven Six Sigma continuous improvement methodologies?

This can best be answered by considering the expectations, the conflicts and the different levels of understanding surrounding the term zero defects. Literally zero defects corresponds to a defect level of infinity sigma, which most practitioners will admit is not possible.

And yet an enthusiastically institutionalized zero defects program may unfortunately promote the belief and expectation that true zero can and should be achieved. Defects, depending on their size and type, have different probabilities of impacting the finished product.

And these probabilities depend on the technology. Many defects are simply neutral. If all defects are considered bad, then prioritization is difficult.

It is the role of statistically minded scientists and engineers to classify defects and their potential impact, based on data and engineering judgment.

This allows them to systematically reduce defect levels in a prioritized fashion, starting with the worst and progressing toward the more benign. The ability to prioritize is absolutely necessary in the continuous improvement process.

The statement that if fewer defects are produced, then less inspection will be required is incorrect. Actually, the opposite is true. A higher level and sophistication of testing is required to detect a smaller level of defects.

The particular curve in Figure 1 corresponds to a probability of detection of 95 percent. In other words, if a defect is present at the indicated level x-axisthere is a 95 percent probability that at least one failed unit will be detected using the sample size indicated on the y-axis.

If a shoebox full of needles is mixed into a haystack, only a portion of the haystack will have to be moved before the presence of needles is detected. If there is only one needle in the haystack, every straw may have to be moved before it is found, assuming it is not missed entirely.

This is really the misunderstanding that drives the inappropriate application of a zero defects policy to multiple points along the supply chain Figure 2. This implies, then, that any zero defect inspections prior to the escape point may be non-value-added.

A High-level Flow of Serial Product Manufacture, Across Supplier and Customer Boundaries Ideally suppliers need to produce the highest quality output possible, in order to maximize yield and minimize costs which ultimately benefits both the supplier and the customer.

But a zero defects policy does not provide this motivation to suppliers. When the goal of zero defects is applied to multiple interim points along the supply chain, the undesired effects of increased costs and lower yields are encouraged.The use of slogans such as "zero defects" to spur quality can be counterproductive, detracting attention from the tried-and-true tools and culture associated with successful Six Sigma programs.
