Defining Successful Technology: Needs, Expectations and Experiences

Sari Kujala


Many software products and services are disappointing for humans and organizations. In this talk, I present my research journey defining what is successful technology from the human point of view and how to develop successful solutions. My story as a researcher started from user involvement and identifying implicit needs. The focus of my work was on utility and usability and we could show that involving users leads to better usability and more successful software projects. Soon I broadened my view to motivational and emotional aspects of products as the final acceptance of the product depends on user experience – the emotional evaluation of the product. My contribution to the topic is especially studying the evolvement of user experience over several months. I found that the first impressions and expectations influence later experiences and emotionally strong peak experiences change the overall evaluations of the product. User experience influences users’ willingness to use the product and recommend it to friends. Thus, it is essential to product development companies and organizations in creating user acceptance, business, and brand value.
