The document discusses different methods for conducting user experience testing on a budget, including hallway testing, filming, and experience mapping. Hallway testing involves testing processes and wireframes with employees before launch, and can provide insights from testing scenarios such as booking leave with 15 landings and over 1,500 employees available to test. Filming involves observing users over the shoulder without interfering as they complete tasks to identify navigation, search terms, and steps used. Experience mapping shows pain points and successes clearly while capturing thoughts and feelings. The document advocates for a blend of testing methods before, during, and after development to continuously improve services.
