We look for evidence of results. This can be numerical (sales visits arranged, turnover etc) or soliciting feedback from colleagues, such as the one below:
“Bill, Peter asked me to respond re his response to coaching. I can say unequivocally that Peter is a different man to work with. Very positive, very can do, very willing and appears to have a much more competitive and optimistic outlook on life. Trust this helps. Thank you for having such an impact”.
