This paper proposes a "special-skills payment-base'.. from competitive advantage viewpoint, which is defined by two dimensions, "competitive advantage of human resources" and "explicitness of job worth." It'll increase core employees' accomplishment sense, commitment, satisfaction, and decrease the employees' turnover. Two high-tech companies had been studied to illustrate the pay system proposed. The paper emphasizes certain positions shouldn't be given more priorities of special skill- based pay unless development for a competitive advantage is needed. It also helps discovering positions to be potential source of competitive advantage and better decisions can be made.
