The Impact

This research explores the nature of collective leadership by examining the boundary conditions of how and when it relates to unit functioning. Building from a contingency perspective that considers the impact of contextual factors, we propose that collective charismatic leadership will be associated with lowered unit conflict, and this relationship will be strengthened by the contingency elements of individual charismatic leadership, task complexity, and social inclusion. Furthermore, we propose that the interactions of collective charismatic leadership with these contextual factors will relate to performance and satisfaction through conflict. We examine our hypotheses across two unit-level field studies, and the results illustrated that high levels of these contextual factors enhanced the negative relationship between collective charismatic leadership and conflict, which generally mediated the relationships between these interactive effects and performance and satisfaction. The results also highlight the detrimental aspects of collective leadership and how it can relate to reduced unit functioning when it is not aligned with an appropriate context. Overall, these findings begin to provide a more complete picture of collective leadership from a contingency perspective through a greater understanding of when and how it is related to unit functioning.

Knowledge Value

Employees utilize their informal social networks for acquiring system-related knowledge during enterprise technology implementation. Prior research on knowledge acquisition through social networks has not considered the domain proficiency of knowledge sources or the quality of knowledge flows. This study assigns domain-proficiency levels to knowledge sources and introduces the concept of knowledge value: the net impact of acquired knowledge on performance outcomes. Conceptualized as the differential in the domain proficiency of the knowledge source and the knowledge recipient, knowledge value is examined in the context of both factual and applied knowledge, in relation to task complexity and its influence on performance outcomes. Data collected during the implementation of an enterprise resource planning system indicate that knowledge value has a significant impact on performance outcomes, but the impact of applied knowledge is moderated by task complexity. The results stress the importance of considering domain proficiency of knowledge sources during knowledge-network modelling.

Performance Research

A study was conducted to determine how well the display format effects described by Tullis (1983, 1984) and the resulting prediction equations could be generalized to other display situations. Task complexity and visual monitoring load were identified as task variables which could potentially moderate the format effects and, thus, were varied factorially. The current study also sought to extend Tullis's findings to tasks where the use of several pieces of information from predictable display locations is required. In general, the data indicate the need to study Tullis's format dimensions more fully before using his regression equations to evaluate display designs for use outside the task situation in which the equations were developed. Also, subjects were unable to evaluate their performance accurately under alternative display designs. Their evaluations seemed to be determined mostly by the perceived ease with which information was extracted from the display. This outcome should serve as a warning to system designers. That is, empirical human performance research should be conducted when performance is the paramount design criterion and a validated prediction system, such as the one developed by Tullis for search, is not available.
