I work with industrial equipment and for us quality checks are part of the manufacturing process at every stage. You have to maintain a structured process to ensure a level of quality. It's quite rigid. To translate this process to vendor content creation (or a Certification process by others) it would mean the vendor (or Certifying body) would have to have a certain amount of self disipline and a systematic approach to content creation. All very boaring stuff that sucks the fun out of the job.

How would you set up the certification process?
