Evaluating affective issues: challenge and engagement  in a collaborative immersive game. Improving a design: the HutchWorld patient support  system.

Why, what, where and when to  evaluate examines: Why: to check that users can use the product and that they  like it.  What: a conceptual model, early prototypes of a new  system and later, more complete prototypes. Where: in natural and laboratory settings. When: throughout design; finished products can be  evaluated to collect information to inform new products. Designers need to check that they understand users’  requirements.

Bruce Tognazzini tells you why you  need to evaluate “Iterative design, with its repeating cycle of design and  testing, is the only validated methodology in existence  that will consistently produce successful results. If you  don’t have user-testing as an integral part of your  design process you are going to throw buckets of  money down the drain.”  See  AskTog.com  for topical discussions about design  and evaluation.
