IATF 16949 Core Tools Explained

What are Core Tools?

Quality Core Tools are a group of problem solving skills the AIAG requires to evaluate and improve your Quality Management System (QMS).  There are many statistical tools used to solve problems, but the AIAG has determined that the five tools below are a core requirement for evaluating your QMS.  If your company is seeking certification to IATF 16949, your Internal Auditors will need to be competent (and prove it) in these core tools in order to meet the requirements.

If you are carpenter, you need to have a few basic (core) tools in your toolbox like a hammer, nails, tape measure, etc.  And, you need to know how to use them.  Quality Core Tools are the five basic statistical tools you need to have in your toolbox, and once you learn how to use them, you will be well on your way to IATF 16949 Certification.
