We highlight important differences between twenty-first-century organizations as compared with those of the previous century, and offer a critical review of the basic principles, typical applications, general effectiveness, and limitations of the current staffing model. That model focuses on identifying and measuring job-related individual characteristics to predict individual level job performance. We conclude that the current staffing model has reached a ceiling or plateau in terms of its ability to make accurate predictions about future performance. Evidence accumulated over more than 80 years of staffing research suggests that general mental abilities and other traditional staffing tools do a modest job of predicting performance across settings and
jobs considering that, even when combined and corrected for methodological and statistical artifacts, they rarely predict more than 50% of the variance in performance. Accordingly, we argue for a change in direction in staffing research and propose an expanded view of the staffing process, including the introduction of a new construct, in situperformance, and an expanded view of staffing tools to be used to predict future in situperformance that take into account time and context. Our critical review offers a novel perspective and research agenda with the goal of guiding future research that will result in more useful, applicable, relevant, and effective knowledge for practitioners to use in organizational settings.
