In one of the first in-depth studies to focus on minorities who have made it to the top, Breaking Through examines the crucial connection between corporate culture and the advancement of people of color.

The often surprising conclusions drawn by authors Thomas and Gabarro represent important milestones both for the study of organizational practice and for minorities planning their own course of professional achievement. Here are the determining factors--both individual and organizational--that correspond to the advancement of minority executives to the highest levels.
