Usability Testing: Making it Work for the Army

During an early formative usability test, representative end-users perform a set of tasks using a prototype or simulation of a system. While performing tasks and thinking aloud, a skilled specialist observes and takes notes recording how easily a participant performs the tasks and logging issues encountered. Sessions are conducted in a usability test lab, while interested parties watch from a separate observation room through a one-way mirror. Due to cost, schedule, and resource constraints many elements of conventional usability testing are not viable for use when testing equipment with Warfighters. To overcome these challenges and meet the needs of system developers, usability test procedures were modified and hybrid solutions developed. Descriptions and examples of these modifications are provided as are lessons learned and insights gained through their use during the course of seven usability tests.
