| Consequently, to the educated Quality Professional, ISO 9001 is a living philosophical battleground. In some cases (particularly with AS 9100) the standard even contains contradictory requirements. While ISO 9001 (and all of the QMS standards using it as a base) promotes the concept of continuous improvement, it also mandates the institutionalization of flawed concepts that perpetuate the status quo. Worse, QMS certification to these standards promotes mediocrity and creates a //constraint// hindering innovative improvements. | Consequently, to the educated Quality Professional, ISO 9001 is a living philosophical battleground. And the AS 9100 standard even contains contradictory requirements. |

| When using ANY sampling plan, an AQL (or equivalent) must first be determined. The AQL (defined in [[https://www.iso.org/standard/1141.html|ISO 2859-1:1999]]) represents the maximum percentage of defective units, beyond which a batch is rejected. For example, an "AQL of 1.5%” means “//The company is willing to ACCEPT that there will be no more than 1.5% defective items in the entire order quantity, on average over several production runs//”. Companies usually establish different AQLs for critical, major, and minor defects. \\ | When using ANY sampling plan, an AQL (or equivalent) must first be determined.

| Obviously, if the company must define "corrective actions for nonconforming products and services detected after delivery", then it makes no sense to allow the establishment of ANY sampling plan (including c=0 plans) BECAUSE that sampling plan allows for an ACCEPTABLE number of defects to be shipped! \\ | Obviously, if the company must define "corrective actions for nonconforming products and services detected after delivery", then it makes no sense to allow the establishment of ANY sampling plan (including c=0 plans) BECAUSE that sampling plan allows for an ACCEPTABLE number of defects to be shipped! \\ |

| Even more interesting, AS9101F, sec. 3.3 defines a "Major Nonconformity as: \\ | Even if we adopt a more lax interpretation of the above requirement, AS9101F, sec. 3.3 defines a "Major Nonconformity as: \\ |
