“Coaching that addresses effort is motivational in character; its functions are to minimize free riding and to build shared commitment to the group and its work. Coaching that addresses performance strategy is consultative in character; its functions are to minimize thoughtless reliance on habitual routines and to foster the invention of ways of proceeding with the work that are especially well aligned with task and situational requirements and opportunities. Coaching that addresses knowledge and skill is educational in character; its functions are to minimize suboptimal weighting of members’ contributions and to foster the development of members’ knowledge and skill.”
