It is important to give feedback in a considered, structured manner at an appropriate time in the appropriate environment.
Good feedback will allow the person receiving it to review, consider and understand what has happened and their role in it. The process should also allow them to reflect and plan action points about how they could use the learning to improve their practice in future.
Lose the emotion – if you are feeling anxious or angry about an event or issue you are unlikely to be able to give or receive feedback effectively. Try and remain professional in your communication when you undertake this.
Respectful communication being mindful of the BEMOS model will help you recognise poor workplace behaviour and plan solutions.
