The Whole Message model is a helpful tool that is just as easily applied to giving feedback upwards as it is downwards or across the organisation. When used correctly in giving developmental feedback, it can reduce defensiveness in the recipient and prompt a discussion on change. Try using the Whole Messages model to give positive feedback, too. Chances are that the recipient will not only remember what was valued, but will repeat the behaviours that you have reinforced.
The model is shown here. To know how to use it appropriately, it is strongly recommended that you download the full 10 pages on Whole Messages.
