How can employee diversity create a competitive advantage?

"Some of today’s most important trends in human resource management are using employee diversity as a competitive advantage, improving efficiency through outsourcing and technology, and hiring employees who fit the organizational culture. Although overall labor union enrollment continues to decline, a possible surge in membership in service unions is anticipated. American society and its workforce are becoming increasingly more diverse in terms of racial and ethnic status, age, educational background, work experience, and gender. A company with a demographic employee profile that looks like its customers may be in a position to gain a competitive advantage, which is a set of unique features of a company and its product or service that are perceived by the target market as superior to those of the competition. Competitive advantage is the factor that causes customers to patronize a firm and not the competition. Many things can be a source of competitive advantage: for Southwest Airlines it is route structure and high asset utilization; for Ritz-Carlton hotels it is very high-quality guest services; for Toyota it is manufacturing efficiency and product durability; and for Starbucks it is location, service, and outstanding coffee products. For these firms, a competitive advantage is also created by their HR practices. Many firms are successful because of employee diversity, which can produce more effective problem-solving, a stronger reputation for hiring women and minorities, greater employee diversity, quicker adaptation to change, and more robust product solutions because a diverse team can generate more options for improvement. In order for an organization to use employee diversity for competitive advantage, top management must be fully committed to hiring and developing women and minority individuals. An organization that highly values employee diversity is the United States Postal Service (USPS). In 1992 the Postal Service launched a diversity development program to serve as the organization’s “social conscience and to increase employees’ awareness of and appreciation for ethnic and cultural diversity both in the postal workplace and among customers.” Twenty-five years later, 39 percent of postal service employees are minority persons: 21 percent African-American, 8 percent Hispanic, and more than 8.0 percent other minorities. In addition, women make up 40 percent of the organization’s workforce."
