Do the practitioners' level of systems-thinking skills differ across sector types?

The turbulent nature of the business environment is increasing with the complexity of solving problems and making accurate decisions. In response, system thinking has been considered as a potential solution that offers a comprehensive understanding of organizational structures. Addressing problems in complex systems requires not only technical and business knowledge but also good understanding of organization ownership structure and sector type where practitioners they are working at. This research assesses practitioners' level of systems thinking (ST) skills based on the sector type they are working at. It is hypothesized that practitioners from different sectors possess strength in different ST skills. A cross-sectional survey was conducted to collect the data from practitioners from different sectors, followed by a multi-group structural equation modeling and post-hoc Tukey HSD tests to compare an individual's systems thinking skills across three different groups of private, non-profit, and public sectors. Research results provide some insights on how sector type moderate a practitioner's systems thinking aptitude toward complex problem-solving.
