This document reports on findings from a study on decision styles and their influence on leadership and engagement. It summarizes that:
1) There are four main decision styles (Decisive, Flexible, Hierarchic, Integrative) based on how much information people use and their focus, which can influence performance depending on the situation.
2) A study of 180,000 managers found different decision style profiles were most successful at different levels of leadership, showing styles must change to fit the requirements of higher roles.
3) Participants' own styles influenced what qualities they saw as good or bad in past leaders, valuing styles similar to their own.
