The 3Cs of Critical Web Use: Collect, Compare, Choose
The three Cs, collect, compare, and choose, describe most of the Web's critical use. As a result, we should make sure to include test tasks that address these issues when we plan usability studies of websites.

Jakob Nielsen, Ph.D., is a User Advocate and principal of the Nielsen Norman Group. Dr. Nielsen founded the "discount usability engineering" movement for fast and cheap improvements of user interfaces and has invented several usability methods, including heuristic evaluation. He holds 56 United States patents, mainly on ways of making the Internet easier to use. http://www.useit.com
