improvements were clearly evident; as; democratic leadership style
Step-by-step explanation:
What this means is that;
"Adrienne is part of the senior management team at a company in which improvements were clearly evident since her appointment, as both morale and client-satisfaction have dramatically improved. Among her driving principles is the idea that people work better when they are both motivated and empowered to reach their goals, that each team member must contribute fully, and that when she has to make a key decision, everyone knows why she is making it. She is a useful example of how democratic leadership style works."
