This research builds on Implicit Leadership Theory, which suggests that a leader's performance is likely to be higher when there is congruence between a follower's prototype of what a leader should be and his or her perception of the leader's behaviour. The essence of effective leadership, according to this theory, is being seen as a leader by others. Data were collected from 196 leaders and 1,738 followers from 23 countries within Cargill Incorporated, a US food and agricultural multinational. The research was conducted in two phases. During the first phase data were collected on followers' desired leadership values and their perception of their leader's behaviour on the same dimensions. These data were used to compute a congruence score based on a weighted sum of absolute differences. The congruence score data formed the heart of an individualised Leadership Fit Report written for each leader in the study showing the extent of congruence across 21 leadership characteristics (see Appendix A). The second phase of the study focused on a subset of 933 followers from five countries testing the two hypotheses. The two hypotheses in Phase Two were partially supported. The first was that congruence between desired leadership values and perceived behaviour leads to high performance of a leader and incongruence leads to lower performance. The second was that the relationship between congruence and leader performance varied by nationality. The cross-cultural test of Implicit Leadership Theory captured in Hypothesis 2 was particularly important to Cargill because it revealed unique and important differences between the five countries included in the second data set. This study found that the nature of the relationship between congruence and leader performance varies significantly between all five countries. More specifically the data suggests that congruence does not always lead to high performance. This study, albeit exploratory, makes theoretical, methodological and practical contributions in the following ways. i. A cross cultural test of Implicit Leadership Theory in a multinational organisation with a significant sample size. ii. An existing desired leadership values questionnaire was used and developed further to measure leadership values and leader perception. iii. All 196 leaders received a personalised feedback report showing the level of congruence (or degree of fit) for 21 leadership characteristics. iv. A methodological contribution was made by using Polynomial Regression Equations and Response Surface Methodology to measure the nature of the relationship between desired leadership values, perceived behaviour and leaders' performance. Implicit Leadership Theory was shown to be complex yet very relevant to management practice. The research undertaken was exploratory yet it has created the basis for on going discussion.
