If you, as a certification manager, are facing this issue, there are a few ways to alleviate the problem.
1) Schedule a meeting with all senior Directors and VPs.
2) Prepare a presentation outlining the positive features and benefits of a well developed program - training registration goes up, customers gradually becomes more loyal, a new revenue stream from exam registration, a new revenue stream from exam preparation classes and study guides and most of all, a tangible way to measure the effectiveness of training and product knowledge.
3) Encourage all senior staff to become certified and carry the certification logo on company business cards.
