Iterate

Why
Iterating is important because the product will never be perfect and iterating allow us to improve the product in rounds based on the feedback we've collected.

What
Iteration is a step in task centered design that advocates reevaluating and revising our system based on input we've received in previous steps of the design process.

Steps

 * 1) Examine any places where the user made mistakes or there is some other bug or change to be made
 * 2) Weigh the cost and benefits of doing this change
 * 3) Proceed until the costs are prohibitively high or there are no more changes to be made
