IATF 16949 and ISO Compatibility

Answer:

IATF 16949 covers all requirements of ISO 9001:2015 plus additional requirements specific to the automotive industry. If you are compliant with ISO 9001:2015, you need to implement only the additional requirements of IATF 16949. Some of IATF 16949 requirements require the organization to implement changes to the existing ISO 9001 processes (e.g. document control, internal audit, management review, etc), and some require entirely new processes to be established (e.g. product safety, total productive maintenance, etc)
