UX design (also known as interactions design or user-oriented development) is a tool to minimize risk:
Risk of wasting time, risk of wasting money, and risk of building a poor product.
By using the users' needs as a starting point and viewing the experience through their eyes one can design software, products and services that are effective, problem-solving and that customers want to continue to use.
As a social anthopologists my expertise lies in understanding people's goals, behaviours and contexts. As a UX designer I use such data and insight to create solutions that serve the user, that serve the environment and climate, and that serve your company/organization.
