Figure 5. — Information architecture studies were a critical component of the system development. Iterative testing and improvement was required to ensure successful completion of critical tasks. This figure shows a depiction of a card sort testing analysis of the early menu structure. Participants were asked where they would go to change the background theme image for the PDM lock screen. During the early development phases, the information architecture was confusing to users as indicated by the red color showing failure to find the lock screen image. Tests such as these provided necessary guidance and data to help structure the navigation and flow of information within the system.
