| If sustainable competitive advantage
depends on work-force skills, American firms have a problem. Human-resource
management is not traditionally seen as central to the competitive survival of
the firm in the United States. Skill acquisition is considered an individual
responsibility. Labor is simply another factor of production to be hired—rented
at the lowest possible cost—much as one buys raw materials or
equipment. The lack of importance attached to human-resource management can be seen in the corporate hierarchy. In an American firm the chief financial officer is almost always second in command. The post of head of human resource management is usually a specialized job, off at the edge of corporate hierarchy. The executive who holds it is never consulted on major strategic decisions and has no chance to move up to Chief Executive A. They attach more importance to workers than to equipment. B. They will spend time and money training workers. C. They see the gaining of skills as their employees own business. D. They hire people at the lowest cost regardless of their skills.
