Use the "How well do I master basic management behaviours?" survey to reflect your current ability to master the behaviours required by a great leader.
Use the "How effective is my manager?" survey to collect feedback from your team members on how they experience being led by you.
Depending on how experienced you are and how well you are ranked by yourself and your team, the frequency of how often you conduct these surveys may range anywhere from 3 - 12 months.
