Structure and the Performance of Public Organizations: Task Difficulty and Span of Control

Scholars of public organizations have long been interested in understanding how organizational structures shape organizational performance. This is an important question because if links between structure and performance exist, then manipulating organizational structures may lead to improvements in organizational performance. This study examines how one structural attribute, span of control, shapes performance in a large set of public organizations. Specifically, our focus is on how structure shapes performance when task difficulty varies. We hypothesize that structural attributes such as spans of control have limited effects on performance when organizations address very easy or very difficult tasks. When organizations address moderately difficult tasks, the impact of structure on performance should be greatest. Our analysis of 678 school districts in Texas covering the years 1994 to 1997 reveals that span of control variables have the greatest impact on student performance under moderately difficult task scenarios.
