Book excerpt: How have women managed to break through the glass ceiling of the business world, and what management techniques do they employ once they ascend to the upper echelons of power? What difficult situations have these female business leaders faced, and what strategies have they used to resolve those challenges? Junctures in Women’s Leadership: Business answers these questions by highlighting the professional accomplishments of twelve remarkable women and examining how they responded to critical leadership challenges. Some of the figures profiled in the book are household names, including lifestyle maven Martha Stewart, influential chef Alice Waters, and trailblazing African-American entrepreneur Madame C.J. Walker. Others have spent less time in the public eye, such as Johnson & Johnson executive JoAnn Heffernan Heisen, Verizon Senior Vice President Diane McCarthy, Wells Fargo technology leader Avid Modjtabai, Xerox CEO Ursula Burns, Spanx founder Sara Blakely, inventor Jane ni Dhulchaointigh, engineering firm President Roseline Marston, Calvert Investments President and CEO Barbara Krumsiek, and Merrill Lynch executive Subha Barry. These women, from diverse backgrounds, have played important roles in their respective corporations and many have worked to improve the climate for women in male-dominated industries. This is a book about women who are leading change in business. Their stories illuminate the ways women are using their power and positions—whether from the middle ranks or the top, whether from within companies or by creating their own companies. Each case study in Junctures in Women’s Leadership: Business includes a compelling and instructive story of how a woman business leader handled a critical juncture or crisis in her career. Not only does the book offer an inspiring composite portrait of women succeeding in the business world, it also provides leadership lessons that will benefit readers regardless of gender.
