Pugh's Array is a decision-making tool used to evaluate and compare multiple options or solutions against a set of criteria. It helps teams visualize the strengths and weaknesses of each option, making it easier to identify the best choice. The method involves creating a matrix where options are listed along one axis and criteria along the other, allowing for a systematic comparison. In a Pugh's Array, each option is scored based on how well it meets the criteria, often using a simple scoring system. This structured approach promotes objective analysis and encourages collaboration among team members, leading to more informed decisions in projects or product development.
