Purpose
UCD answers questions about users and their tasks and goals, then uses the findings to make decisions about development and design. UCD of a web site, for instance, seeks to answer the following questions:
- Who are the users of the document?
- What are the users’ tasks and goals?
- What are the users’ experience levels with the document, and documents like it?
- What functions do the users need from the document?
- What information might the users need, and in what form do they need it?
- How do users think the document should work?
- What are the extreme environments?
- Is the user multitasking?
- Does the interface utilize different inputs modes such as touching, spoken, gestures, or orientation?

Famous quotes containing the word purpose:
“The chief want, in every State that I have been into, was a high and earnest purpose in its inhabitants. This alone draws out “the great resources” of Nature, and at last taxes her beyond her resources; for man naturally dies out of her.”
—Henry David Thoreau (1817–1862)
“Natural selection, the blind, unconscious, automatic process which Darwin discovered, and which we now know is the explanation for the existence and apparently purposeful form of all life, has no purpose in mind. It has no mind and no mind’s eye. It does not plan for the future. It has no vision, no foresight, no sight at all. If it can be said to play the role of the watchmaker in nature, it is the blind watchmaker.”
—Richard Dawkins (b. 1941)
“In considering the policy to be adopted for suppressing the insurrection, I have been anxious and careful that the inevitable conflict for this purpose shall not degenerate into a violent and remorseless revolutionary struggle.”
—Abraham Lincoln (1809–1865)
