While training has been a proven and heavily relied on intervention to impart job-enabling information to performers, its ability to have a positive effect on job performance has been demonstrated to diminish over time. One intervention that has been adopted by performance technologists to provide ongoing support is an electronic performance support system (EPSS). The study presented here examined the effect of EPSS and training on user attitudes. Results revealed that participants receiving only EPSS and those receiving training and EPSS had significantly higher attitudes than participants who received only training. Recommendations on how to best combine and implement these performance interventions based on these data are discussed. (Contains 3 tables and 6 figures.)
