Explain to a colleague your motivation for arguing for one approach over another. Provide insight into why ‘your’ approach is so important to you.
When someone brings forward a concern, tell them how you are going to attempt to address the concern, who you are going to consult with on next steps and how you plan to advise them on next steps.
