One of the core principles of UX is to solve existing problems, or problems that people are already struggling with. While this might not be as glamorous as inventing a brand new thing it is more practical: it makes identifying problems easier and people are much more receptive to your design. If you’re solving a known problem you don’t have to convince anybody that your design is valuable…they already know exactly why they want to use it.
Amid the continuing debate over whether PR or Marketing should own social media, I have another suggestion. Let the User Experience team own social media. Why? Because PR and Marketing are all about the company. User Experience is all about the customer. And successful social media is also all about the customer.
User Experience professionals, such as information architects, have training in user-centered design. They are the people who do research to identify the users of your website or product, identify traits or characteristics of these people, create personas to describe them, determine the users’ goals, and design a product or website that meets those goal.
