Abstract:

Four of your fellow development team members, all trying to do their specific jobs to the best of their abilities, have the power to sink your best effort at interaction design. As an interaction designer, it is your job to see they don't do so. (If you are not an interaction designer, read on anyway; you may be surprised to learn that you may be part of the problem.)
