The following is an excerpt from the CoachStart Manual.
There are a multitude of specific coaching niches, with more being identified every day. The major areas of specialization at present include: Life Skills, Business Coaching, Executive Coaching, Corporate Coaching, Career Coaching, Relationship Coaching, Financial Coaching, Study Skills, Fitness and Weight Control, and overall Personal Development.
A typical life skills program may look at clarifying values and visions, setting goals and new actions so that an individual may lead a more satisfying, successful, and fulfilling life.
Business coaching can be useful in any type of business, small or large, and may range from individual skill development to overall team coaching in larger corporations. Areas that often benefit from coaching include communication skills, time management, strategic planning, increasing market share, improving workplace efficiency and productivity and dealing with specific conflicts within the workplace.
If you were working with small business owners and possibly their staff, you would normally call it Business Coaching. If you were working with staff within a corporation, usually paid for by the corporation, or working with the board or leadership team, you would call it Corporate Coaching. Working with individuals in executive positions is of course Executive Coaching, but clearly there can be a lot of overlap between this and Corporate Coaching.
