                        (Speier & Frese, 1997) and developing ideas and suggestions within an organizational
                        suggestion system (Frese, Teng, & Wijnen, 1999). Additionally, self-efficacy has been of
                        particular importance in the learning process. For example, in a careful process analysis,
                        Mitchell, Hopper, Daniels, and George-Falvy (1994) have looked at the effects of self-
                        efficacy on learning. In the beginning of the learning process, self-efficacy is a better
                        predictor of performance than goals, while this relationship is reversed at a later stage.
                          Moreover, professional experience shows a positive, although small relationship with
                        job performance (Qui˜nones et al., 1995). Additionally, there are interactions between
                        predictors from several areas. For example, high achievement motivation was found to
                        enhance the effects of high cognitive ability (O’Reilly & Chatman, 1994).

                        all, the individual differences perspective suggests a focus on personnel selection. For
                        ensuring high individual performance, organizations need to select individuals on the
                        basis of their abilities, experiences, and personality. The individual differences perspec-
                        tive also suggests that training programs should be implemented which aim at improving
                        individual prerequisites for high performance. More specifically, training should address
                        knowledge and skills relevant for task accomplishment. Furthermore, exposing individ-
                        uals to specific experiences such as traineeships and mentoring programs are assumed
                        to have a beneficial effect on individuals’ job performance.


                        SITUATIONAL PERSPECTIVE

                        The situational perspective refers to factors in the individuals’ environment which stim-
                        ulate and support or hinder performance. The core question to be answered is: In which
                        situations do individuals perform best? The situational perspective encompasses ap-
                        proaches which focus on workplace factors but also specific motivational approaches
                        which follow for example from expectancy theory (Vroom, 1964) or approaches which
                        aim at improving performance by reward systems or by establishing perceptions of equity
                        and fairness (Adams, 1963; Greenberg, 1990). Most of the existing leadership research
                        can be subsumed under this perspective. Because of space constraints, we will concen-
                        trate on workplace factors as major situational predictors of individual performance.
                        Interested readers may refer to Folger and Cropanzano (1998), Lawler (2000) and Van
                        Eerde and Thierry (1996) for specific motivational approaches, or to Yukl (1998) for
                        research within the leadership domain.
                          With respect to workplace factors and their relationship to individual performance two
                        major approaches can be differentiated: (1) those that focus on situational factors which
                        enhance and facilitate performance and (2) those that attend to situational factors which
                        impede performance.
                          A prominent approach within the first category is the job characteristics model
                        (Hackman & Oldham, 1976). In this model, Hackman and Oldham assumed that job
                        characteristics (i.e., skill variety, task identity, task significance, autonomy, feedback)
                        have an effect on critical psychological states (i.e., experienced meaningfulness, experi-
                        enced responsibility for work outcomes, knowledge of the results of the work activities)
                        which in turn have an effect on personal and work outcomes, including job performance.
                        Additionally, they expected an interaction effect with employee growth need strength.
                        In essense, the job characteristics model is a motivational model on job performance
