Human resource (HR) flexibility emerges as the most critical source of flexibility for professional services firms (PSFs), given that the success of these companies depends on the knowledge, expertise and behaviors of their employees. Nonetheless, few empirical studies have analyzed the extent to which the characteristics of the workforce explain the results of this type of firm. This study attempts to advance in this line of research by analyzing the influence of HR resource flexibility dimensions (skill flexibility – SF and behavior flexibility – BF) on PSF performance. It also examines whether HR coordination flexibility (CF) strengthens the effect of SF and BF on performance. Matched data from 97 general managers and 291 professionals in a sample of Spanish PSFs is used to test the hypotheses through structural equation modeling methodology. The study demonstrates that employee BF has a significant effect on the development of new services in PSFs. The moderation model shows that HR CF increases the influence of BF on the development of new services. Contrary to what was expected, no significant relationship between SF and PSF performance was found.

专业服务公司的人力资源灵活性和公司绩效

人力资源 (HR) 灵活性成为专业服务公司 (PSF) 灵活性的最关键来源，因为这些公司的成功取决于其员工的知识、专长和行为。尽管如此，很少有实证研究分析了劳动力特征在多大程度上解释了这类公司的结果。本研究试图通过分析 HR 资源灵活性维度（技能灵活性 - SF 和行为灵活性 - BF）对 PSF 绩效的影响来推进这一研究方向。它还检查了 HR 协调灵活性 (CF) 是否增强了 SF 和 BF 对绩效的影响。来自西班牙 PSF 样本中 97 位总经理和 291 位专业人员的匹配数据用于通过结构方程建模方法检验假设。研究表明，员工 BF 对 PSF 中新服务的开发具有显着影响。调节模型表明 HR CF 增加了 BF 对新服务开发的影响。与预期相反，没有发现 SF 和 PSF 性能之间存在显着关系。
