Why Learn this Theory?

The actions we’ll discuss often happen in one to four seconds, making it difficult to articulate.

This theory provides a common construct & vocabulary in describing how a user interacts with the World, or a computing system to accomplish a goal.

Applying it ensures a more thorough and consistent task and design analysis.

Can’t Cross the Gulf of Execution?

Ask – Is the intention obvious & does it match the user’s intent?

Ask – Is the action well specified in terms the user can understand?

Ask – Can the user manipulate the control?

Can’t cross the Gulf of Evaluation?

Ask – Is state change perceptible?

Ask – Can the state change be interpreted?

Ask – Can the state change be compared to the user’s desired outcome?
