Most inspections only involve 1 or 2 references, and can be conducted in one man-day (i.e. one inspector on site for one day). However, in certain situations, deciding on a sample plan is very difficult–see my previous article about shipments including many references.
This is one of the most difficult things to explain to my clients. Fortunately, my designer managed to explain it all nicely in this illustration:
- To see the whole statistical tables, you can go to AQL tables.
- To understand how to read these tables, you can read Get familiar with AQL tables.
Does this illustration do a nice job of clarifying this issue?
