Both formal and informal critiques are helpful. To ensure that we get the most out of them we need to consider the right type of critique setting for the situation. Formal critiques provide a dedicated, predictable time, and as such, they typically give us an opportunity to collect a wider range of perspectives because we can gather more people. Informal critiques provide designers with a way to quickly collect feedback and get answers to pressing questions so that they can continue working on their solutions instead of waiting for a scheduled meeting.
