We use this one-page Evaluation sheet to review a service, product, or idea. It prioritizes the user’s point of view — to make sure that the thing you’re reviewing has a good user experience. It can be used for proposals or existing things.
The sheet forces the reviewer to give a number on each factor, but the main thing is not a score-card, but thinking through where there is opportunity to better match the thing with the user’s needs and aspirations.
