Identifying users can be done using several techniques, such as user interviews, business stakeholder interviews and and the “shadowing” method of observation. Interviews can give you answers to questions about the users’ knowledge of the system and computers in general, while shadowing can yield more detailed information about how users perform tasks and what errors they make. The method is called shadowing because the observer is like a shadow, watching and noting the steps a user takes.
If you don’t have access to real users—either because you don’t have permission or are designing for open application—you can use personas, a tool to help identify users. Personas are a representation of real users, including their habits, goals and motivation. Because certain information about users is often identified through business analysis, you can make use of it to create personas. If you are not familiar with the tool, a comic by Brad Colbow will help.
Task analysis helps identify what tasks users perform in their jobs, how they do them, how long they take and what errors they make. Sometimes clients will be using an old version of the application that you are designing to replace. Make use of that old system and watch how users use it. Understanding their tasks and challenges will be easier that way.
Regardless of who your users are, one thing is certain: in most cases, you will have to consider both novices and experts. Novice users should be enabled to learn as fast as possible, while expert users should be enabled to perform their tasks extremely efficiently. This may mean creating separate interfaces. But in many cases you will be able to accommodate both types of users in the same interface through various techniques, such as progressive disclosure.
Such research is usually done by business analysts. But if no one else is responsible for it, you should do it. Once you have the necessary information, you can begin with design.
