Good feedback is one of the most valuable things a piece of design can get. It is also one of the hardest things to give, which is why we practise it on each other’s work every week.
Describe the problem, not the fix
“Make the logo bigger” is a solution. “I’m worried people won’t notice who this is from” is a problem, and it might have a better answer than a bigger logo. Say what feels wrong and why. Let the designer find the fix.
Go back to the question
The most useful question to ask of any design is not “do I like it?” but “does this answer what it set out to answer?” Tying feedback to the original question keeps the conversation honest and the work on course.
Say what is working
Knowing what to keep is as important as knowing what to change. If one part of a design feels right, say so. It stops good ideas being lost in the next round.
Gather everyone’s views first
One set of combined notes is far better than five separate emails that contradict each other. Agree internally, then share. It makes every round faster, and it makes the final result better.
