Useful feedback is specific, timely, and actionable. Vague praise feels nice; vague criticism creates anxiety. Both leave the person unsure what to repeat or change.
Separate the person from the work. Describe what you observed, the impact, and the preferred next step. Example: the client deck missed two requirements, which delayed the send, so next time use the checklist before sharing.
Give feedback close to the moment when memory is fresh, and in a setting that protects dignity. Public feedback is fine for recognition; private is safer for course correction.
Close the loop. Agree on a next action and a time to check progress. Feedback without follow-through becomes noise. Teams that practice this habit reduce ambiguity and build trust faster.
