When I first became a manager I was taught these basic management skills. I have literally carried these five basic skills with me at all times over the years. One of my early mentors laminated and gave them to me when I became a manager. I have seen different variations but at their core they remain the same.
1) Lead by example
2) Focus on the situation or behavior, not the person
3) Treat others with respect
4) Maintain two way conversations that are open & honest
5) Take it upon yourself to better the situation
