Using the “7 Actions” Theory for Task and Design Analysis
Why we’re learning about this theory
Cover the origins and components of the theory
How to apply it in task & design analysis
Analyze the design of a common user experience
Apply the theory to a k12 design
10/23/127 Stages of User Action by Heather Crombie
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.

Origins & Components of theory
Proposed by Donald Norman in the 70’s and used in the process of airplane control analysis & design.
It applies to any system or device;Control Systems & Panels for Nuclear Power plantsBureaucratic SystemsOperating SystemsWebsitesDoors

Theory ComponentsUser Goal = Desired Outcome=Epic/User Story
Gulf of Execution: The psychological and physical barriers to achieving a goal.
World = K12 Virtual School System
Gulf of Evaluation: The psychological and physical phenomena that occurs when comparing the goal to the systems’ response to user interaction.

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?
10/23/127 Stages of User Action by Heather Crombie
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?
