Interfering Head Quality

The Quality Head of your company used to be a good technical person. Some time ago, he chose to move to the quality department as part of a reorganisation. However, old habits die hard. Every once in a while the desire to contribute technically resurfaces. The opportunities are always present. While doing a quality audit, he branches off into technical details and at the end of the hour-long audit he ends up changing the design or shredding the requirement or modifying the code. Your technical staff have been complaining, but you let it pass since this guy has immense experience and any technical suggestion cannot be taken lightly. But now it has come to a head. Your technical team has refused to submit to be audited by him. While you do not want to lose out on his experience, the work must go on.
