While executive coaching is a key means by which organisations and individuals build executives’ capabilities, very little research has investigated how effective or beneficial this development tool is to the individuals or the organisations in which they work. The purpose of this study was to examine executive coaching effectiveness by investigating whether executive coaching has an impact on coachee performance outcomes as well as individual outcomes as manifested by self awareness, career satisfaction, job affective commitment, and job performance. Coaching outcomes were examined through a quasi-experimental field pre-post design with an untreated control group. The study participants (n=197) were drawn from the client bases of four Israeli-based firms whose primary professional services focused on executive coaching. The primary conclusion is that executive coaching may be a mechanism by which executives could be helped in improving and maintaining a high level of career satisfaction. The results should assist organizations in designing more effective executive coaching programs, and in making informed decisions about implementing and measuring executive coaching.
