The chapter also summarizes various studies that compared the effectiveness of different usability evaluation techniques. At the end, guidelines for practitioners and an agenda for researchers are offered. After reading this chapter, the audience should gain an overview of the research and practice of usability evaluation and understand the different criteria for selecting the appropriate technique for a particular project.
