We are seeing the development of internal expert coaching teams on specific subject matters. The research
backs this, showing that adding coaching to any kind of training initiative has a very significant impact. One
study done in 1977 by Olivero Bain and Coppelman involving 32 managers over two months found the
training increased productivity by 28%. The training plus coaching increased productivity 88% - almost three
times the impact by adding coaching. Other studies show that coaching increases the effects of training sixfold.
