Curious how most of you handle the review, prioritization and assignment of bugs or issues raised, during the production (in-field) phase of product development?

For example: An issue related to the in-field maintenance of a product is raised, which could be addressed by either a software enhancement or by implementing an operational procedure.

So someone OR some group within the company needs to determine how this issue should be handled and prioritized. Also, the original project team which developed the product has now moved on to another project. So they aren't available to review production bugs/issues with the previous product.

Available options as I see them are as follows:

A. Have the technology and operations managers meet on an as needed or regular basis to review specific production bugs.

B. Make the product manager for each product line responsible for the review and prioritization of all production bugs for their "owned" product.

Any better options out there?
