Product tests are all experiments of a sort. To plan and execute them well, consideration needs be given to:
Often, these tests ask respondents to evaluate more than one product, creating order effects: the influence of the context within which a product is evaluated. These effects can be “balanced out” with an appropriate design… but the design itself does not nullify the effects. Only with an appropriate design can these effects be measured, controlled, and used to better evaluate product performance.
