One of the best ways to learn the user-centered development methodology is to develop a web site for an organization or for a person other than yourself. There are many places where you can find a “client” – many on-campus organizations would like to have a site that publicizes their activities. There are also many nonprofit organizations such as service organizations, theatre troupes, and religious groups that would like to set up web pages but don’t have the skills or resources to do so. Another possibility might be a city department such as a parks district who might be interested.
When you find a client who is interested, ask them what they envision for their web site. If the conversation elicits a large wish list, feel free to ask them which issues are most important to them. With this information in hand, ask your teacher to help you keep the project at a manageable size. After consulting your client and your teacher, write a needs analysis for your client. In it, give a brief description of your users and the benefits they will enjoy as a result of your new web site.
