Abstract:

Unless you have the power to make business and development decisions for your project, some of your energy will be spent influencing those that do. Experienced usability engineers or interaction designers may have limited skill in influence, despite how significantly it can effect their ability to contribute to projects. It’s the smartest and most effective designers that work to understand the human to human interaction within their project teams, as part of their work towards better human to computer interaction.
