Besides my work with different certification bodies, I carry out as well internal (1st Pty) or supplier audits (2nd Pty.).
For your organization, internal audits in preparation for an external audit ( certification/customer) audit or for verifiying the effectiveness of your management system.
Your advantage is my experience as certification a auditor for a long time and in various branches. Annually I carry out 20 to 40 external audits for different certification bodies. This is only possible with a constant training and studying program in place to keep myself up to date with all the requirements - and this is your advantage too.
My auditing activities are mainly according to the following standards /technical specifications
