360 surveys are a great tool that enable leaders to get feedback on their performance.  They require great debrief and thick skin for the person getting the results.  You need to know what you're doing before initiating one.  Fortunately, we have an expert on this topic.  Amy Dunn is a coach, facilitator, and speaker who administers the Leadership Practices Inventory (LPI).  This is a great tool and Amy explains what it does and doesn't do as well as the proper way to debrief it.
