Mickie is an excellent consultant because she says thing like this when asked if she is an advocate for certification programs:
If certification is really right for the field, then I’m an advocate. If it’s not, then I’m not.
Sounds obvious but she makes the point in her post that a lot of consultants are happy to help you build a certification program whether your field needs it or not! You need advisors who will question your basic assumptions before you make significant investments instead of cheering you on without analysis.
