Here is the second video about the ANSI tables (also known as “AQL tables”). The previous video is here.
These statistics were designed for a very specific case, and most buyers are not aware of this. As a consequence, they apply these same statistical tables to all types of situations.
I will cover the cases where it makes sense to use the AQL tables:
- Inspection by attributes
- Lot-by-lot inspections
- Normal vs. reduced vs. tightened severity: the switching rules
- Why single plans are less efficient than double plans
This is not all theory. In each part, I try to mention the key takeaways for buyers.

I hope it’s all clear. Don’t hesitate to ask questions in the comments below.
In the next video we’ll expose something that should be shocking to buyers: the statistics behind the AQL tables are clearly in favor of the supplier.
