| Abstract: | Weitz (1961), aware of the lure of tradition and expedience, urged the identification of evaluation standards for dependent variables, which he referred to as criteria for criteria. In this article, five criteria are proposed using the mnemonic SURF & C: the directness of sampling (S); the responsiveness of the target (i.e., making sure the dependent variable is under (U) the worker's control); the reliability (R) of observers; the frequent (F) assessment of the target during the intervention period; and the critical (C) nature of the target. Together the criteria provide guidelines for what and how targets should be assessed. Their necessity is illustrated in two year-long experiments designed to improve the preventive maintenance of heavy equipment in the U.S. Marine Corps. Although the criteria are limited to evaluating dependent variables in field experiments, they are recommended as the foundation for successful performance efforts in any applied setting. |
