Our CB auditor issued a finding for our management meetings not covering all the required input and outputs of ISO9001:2008 section 5.6.2 and section 5.6.3. When reviewing the cause it was because they were not all listed on the agenda. The reason they were not listed on the agenda was because some of them are covered in our weekly meetings. My reply was too simple I guess. I answered the agenda need to be updated to cover all the input and outputs. The CB auditor came back with wanting more in the root cause. I don't have more to give him. The root cause was they were not on our agenda for the meeting. The effectiveness is that we corrected the agenda, had a new meeting and covered all the inputs and outputs required. What information should I be giving him that is missing in my root cause?
