Artists and designers often record ideas, observations and insights that come to them as they produce their work. These insights can help them to analyse and evaluate the effectiveness of the work that has been produced. Being able to analyse a work is an essential part of evaluating it. Art critiques need to generate facts upon which to base their opinions: namely, facts about (1) the context of the artwork; and (2) the artwork itself. Once we have the facts, we can then make our assessment.
