Receiving feedback:
Be ready to say something about your work

• Keep it brief
  The more you talk, the less time there is for feedback. Using your rationale as a starting point, the group can then discuss whether or not your basic concept is compelling. If the concept is viable, participants should try to offer suggestions that might improve the design execution. If the concept simply isn’t worthwhile, the critique usually concludes quickly.
• Invite constructive criticism
  Encourage participation by openly inviting constructive criticism:
  What do you think is the least successful part of my design—and why?
  Where do you think I can make improvements?
• Listen
  Keep an open mind and avoid being defensive
  The feedback will enable you to adjust and revise your design with the goal of making it more successful. Avoid getting defensive. You don’t have to justify your work.
• Don’t take it personally
  In an ideal world, those offering criticism are respectful and focus objectively and rationally on both the flaws and merits of your design solution.
• Take notes
• Be positive
• After the critique, decide what revisions to make
  After the critique, it’s up to you to decide how to address the issues that were identified. To do this, you need to think critically about the objectives of your design—what exactly the design needs to accomplish—and determine how specific changes can move you toward a more effective solution.

Offering constructive feedback
As a guideline for providing good feedback, avoid using “like” and “don’t like”; instead, use “this works” or “this doesn’t work”, and include why you believe that.

• Use the “hamburger method”
  Try beginning with a positive, constructive comment on something that works well in the design that is being critiqued. Next, get to the meat, which is, of course, constructive criticism—what could be improved. Finally, end with another positive acknowledgment.
• Focus on “why”
  In a productive critique, critics must explain why they do or do not accept the solution being offered by the designer. A detailed analysis of “why” is essential in enabling the designer to improve his or her work.
• Make actionable suggestions
  Try to first point out the problem, then offer several possible solutions, hedging your feedback with phrases such as “it might not work in this case” or “this is just one idea.”
