HR flexibility and firm performance in professional service firms

Abstract

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.
