Abstract: This chapter will be of interest to people wishing to find out more about usability and how to achieve it, and to those responsible for delivering and sustaining usable systems. It introduces the international standards for usability and their use in government system acquisition, and details their requirements for ergonomics and human-centered design (HCD). It describes the ISO process models, HCD processes, and design guidance. It describes the application of the ISO HCD process to government systems from the perspectives of requiring HCD in government system contracts as a means of reducing the risk from poor usability, inclusion in process improvement, product specification, and validation. It also discusses the effect of project scale and provides the details of relevant standards.
