We are surrounded by feedback, whether we're being asked to like, rate or otherwise comment on products, services or even people.

Margaret Cheng's six golden rules and Giving Good Feedback Framework offer a clear guide to what feedback is, how we can master the things that get in the way and deploy some simple techniques to make feedback a more routine - and less emotionally charged - part of our routine work communications.
