Change Happens; Improvement requires Feedback

This is a concept that has been ingrained through my military training.   Things will always change.  Change happens.  I’m always about getting better.  I want to be better personally.  I want projects and systems I’m involved with to improve.   Things will change without anybody doing anything.  Change can be good or bad.  Improvement by definition is good.  This difference is that improvement requires intent and action to provide feedback.   Not everyone has this as part of their ethos.  This is were skill and style come in.  Can you create the environment such that people are willing to accept the feedback so the whole can improve? Can you do this often enough that it becomes part of the organizational and individual’s ethos?  Please share how you do it.  I want to know.
