While some people are initially reluctant to engage in telephone coaching, this trepidation vanishes after the first session. The key to making phone coaching work is having access to a private and quiet location in which to take the calls.
Some leaders prefer to have face to face meetings and while more expensive, these meetings do allow for a different sort of relationship particularly where interruptions and day to day demands of the role can distract from a telephone coaching environment.
Working face to face with a coach eliminates distraction and many executives appreciate taking an hour out of their busy day to focus on their personal development.
In person coaching sessions also allow for the: "white boarding" of ideas, real time illustration of various models and can provide a heightened sense of the client's environment.
The Core Values Index is such a powerful tool that I offer a one-hour phone debriefing session to help people get the most out of the assessment.
This debrief includes a comprehensive report (in pdf format) and a thorough explanation of the CVI model and how to use it to increase your personal effectiveness.
