It is widely recognized that each family has its own unique unwritten rules, values, histories, and communication methods. As the family structure shrinks or expands, the company changes, particularly with the advent of the second and third generations. Changes instigated by new generations can improve or harm the business. A recent survey suggests that only 15% of family-owned enterprises continue to survive to the third generation. Of those that do last, 85% either disintegrate or completely vanish before the fourth generation takes the reins.
