Heuristic analysis is a method used to evaluate the usability of a product, often in the context of software or web design. It involves a set of established principles, known as heuristics, that guide evaluators in identifying usability issues. Common heuristics include consistency, error prevention, and user control, which help ensure that a product is intuitive and user-friendly. During a heuristic analysis, experts review the interface and compare it against these heuristics to pinpoint areas for improvement. This process can be conducted quickly and does not require extensive user testing, making it a cost-effective way to enhance the overall user experience of a product.
