Usage As Design Aids
The seven-stage structure is referenced as design aid to act as a basic checklist for designers' questions to ensure that the Gulfs of Execution and Evaluation are bridged.
The Seven Stages of Action can be broken down into 4 main principles of good design:-
- Visibility - By looking, the user can tell the state of the device and the alternatives for action.
- A Good Conceptual Model - The designer provides a good conceptual model for the user, with consistency in the presentation of operations and results and a coherent, consistent system image.
- Good mappings - It is possible to determine the relationships between actions and results, between the controls and their effects, and between the system state and what is visible.
- Feedback - The user receives full and continuous feedback about the results of the actions.

Famous quotes containing the words usage, design and/or aids:
“I am using it [the word ‘perceive’] here in such a way that to say of an object that it is perceived does not entail saying that it exists in any sense at all. And this is a perfectly correct and familiar usage of the word.”
—A.J. (Alfred Jules)
“Humility is often only the putting on of a submissiveness by which men hope to bring other people to submit to them; it is a more calculated sort of pride, which debases itself with a design of being exalted; and though this vice transform itself into a thousand several shapes, yet the disguise is never more effectual nor more capable of deceiving the world than when concealed under a form of humility.”
—François, Duc De La Rochefoucauld (1613–1680)
“The moral immune system of this country has been weakened and attacked, and the AIDS virus is the perfect metaphor for it. The malignant neglect of the last twelve years has led to breakdown of our country’s immune system, environmentally, culturally, politically, spiritually and physically.”
—Barbra Streisand (b. 1942)
