Whitmore (1992) defines coaching as primarily being concerned with the type of relationship between a coach and coachee, and the means and style of communication used. Whitmore quoted from Timothy Gallwey's The Inner Game of Tennis, "the essence of coaching is unlocking a persons potential to maximize their own performance. It is helping them to learn rather than teaching them". The coaching objective is to develop responsibility and awareness in the coachee which affects the attitude of the mind. Whitmore believes the objective is achieved by setting performance goals that are specific, measurable , attainable, realistic, and time phased .
