How to shortlist executive coaches

There’s a lot of executive coaches out there.  An awful lot.  The Association for Coaching lists over 1,600 members.  The International Coach Federation has over 20,000. There are multiple LinkedIn groups dedicated to coaching practice with 30,000+ members.

The eventual decision on the coaches you choose to work with will often be somewhat subjective (hence why rather vague words like ‘chemistry’ are often used to describe the final stages of selection), but with such a bewildering array of choice, how do you produce a workable shortlist?
