The Defense Industry Reserve Duty System¡]DIRDS¡^has been used in Taiwan for many years. This program enables science and technology industries to recruit talented people, who can contribute to the defense industry and the high-tech industries without interruption by regular military service. This study uses quantitative methodology and interviews with human resources and R&D managers to determine how this program has effected high-tech enterprises from a human resources perspective. Results of this study showed that DIRDS recruits exhibited four characteristics: high stability, high quality, high educational background, and high consistency with industry requirements. Due to these four characteristics, DIRDS recruits have become an important source of IT talent. DIRDS recruits can bring significant growth to R&D efforts and enhance the energy of development. The Defense Industry Reserve Duty System can thus help reduce manufacturing costs, improve operational effectiveness, and raise the prestige of corporate brands. Further analysis and discussion of our results show that for human resources planning, work arrangement with DIRDS recruits should be combined with the company's long term objectives. Recruitment and selection should be focused and strategic since DIRDS targets specialized skills. Training and development should focus on practical or on job training that is tailored to the abilities and temperament of the DIRDS recruit.
