This document summarizes post-test feedback mechanisms for assessing user experiences. It discusses the System Usability Scale (SUS) questionnaire and Product Reaction Cards (PRC). An example is given of an international hotel group that tested a "green" initiative over three rounds, seeing improvements in SUS scores and positive PRC selections. The document encourages using both SUS and PRC to get a comprehensive view of user experience. It provides details on how to administer and analyze PRC in person and remotely.
