Why is a milestone hidden behind a cost bar on a screen?

A user must always see important information. Hidden elements can stop a user from understanding progress. Design choices must account for all on-screen elements.

By Pawan Nayar · from the LLOS AI Learning record

The rule

A user must always see important information.

Hidden elements can stop a user from understanding progress. Design choices must account for all on-screen elements.

A problem in the design made a milestone invisible. The content area had a setting that hid anything outside its box. There was no extra space at the bottom of the content area. A cost bar was fixed at the bottom of the screen. This bar covered the milestone information. The design did not save space for the cost bar.

A developer creates a new screen for an AI model. The screen shows a user's progress toward a goal. A fixed bar at the bottom of the screen shows the cost. The developer does not add space above the cost bar. The progress milestone is hidden behind the cost bar. The user cannot see how much progress they have made.
