Lessons Learned - Is this a Requirement of ISO/TS 16949:2009?

I am loving this forum - thank you to everyone for sharing your knowledge and experience! Question: is the tool "lessons learned" an actual requirement in the ISO/TS 16949:2009 specification (I don't believe it is as I've read it numerous times cover to cover) or is it merely a widely recognized tool that can be used as evidence of an organization meeting the specification's requirement of improving the QMS? Thank you.

 

It's a tool, not a requirement. Good luck.

 

A tool to show evidence of conformance to 8.5.3 Preventive Action.

 

The Phrase "Lesson Learned" as such does not find a place in ISO/TS Standard, at least to my knowledge.
However, something that comes closer or even equivalent is 7.3.2.1 Product Design Input ;
use of information: the organization shall have a process to deploy information gained from previous
design projects, ********, supplier feedback, internal input, field data, and other relevant
sources, for current and ******* of a similar nature;

And also 7.3.2.2 Manufacturing Process Design Input :
- experience from previous developments.

 

Thank you all. Should layered process audits, which are widely used in manufacturing in the U.S., be considered a tool as well which can serve as evidence for the organization satisfying 5.6.2a Review Inputs: Results of Audits? I would not categorize these as a requirement of the standard merely a tool but am looking for opinions on that. Thank you.
