There is a bit of an industry in management coaching so beware of people that don't come with obvious credentials.
Basically people are sold on the idea of management coaching via a franchise model - you can image how a systematise moel could help, but it also means there is a KPI out there wher someone has to be selling franchises. And once there is a KPI (and incntives avaialble) the quality of coaches slips.
I'm not sayiong they are all no good - just to beware.
