3

Mockups / Prototypes

• Rapidly create visual representations (mockups) or interactive representations (prototypes) of the site.
• Evaluate usability through focus groups, user tests, and walkthroughs.
• Use the evaluation results to create more mockups or improve the prototypes.
• Repeat this process (design iteration) until the design and usability goals are met

4

Production

• Create the final product.
• Evaluate functionality through testing, quality assurance, usability testing, and field testing.
• Use the evaluation results to improve the product.
• Repeat this process (production iteration) until the business goals are met.
