User Assistance in the Role of Domain Expert

The need for users with domain expertise for developing Help ...

"This article explores the role of user assistance in providing domain-centric online Help—rather than Help that simply explains obvious user interactions with well-designed user interfaces—and provides a pattern for and examples of expert guidance.

It took two aha! moments for me to get the importance of providing domain expertise in Help. The first came at a conference for writers of user assistance when the technical communications manager for a company that makes home accounting software said, “My challenge isn’t teaching people how to use our software; it’s teaching carpenters how to be accountants.”

The second aha! came during usability testing of the online Help I had written for system administrators of a predictive dialer—a device that dials phone numbers automatically, then if someone answers, connects that person with the first available call-center agent. On one of the screens we were testing, users were to set the Busy Callback Time, which I had defined as: “The time the dialer waits before redialing a line that is busy.” I had specified the minimum and maximum allowed values—0 and 999 minutes, respectively—and even mentioned that users could click an up arrow to increase the value; a down arrow to decrease the value. And, of course, I also told users to click Save to save their changes. Well, when I tested the online Help in the usability lab, I learned the following:

• The label Busy Callback Time was self-explanatory—really, everybody got it right away.
• No one wanted to set the value to less than zero.
• No one tried to set a value that was even close to going over the allowed maximum—and if someone had, the system would not have accepted the value.
• Everyone figured out that whole up arrow and down arrow thing without my help.
• They figured out Save on their own, too.

Still, users went to Help with one simple question: “What’s a good number of minutes to delay before calling back?” It seems that was the only thing I had not documented.

I understood then that Help should provide domain expertise, not just tell users how to manipulate user interface elements."    (Continued via UXmatters)    [Usability Resources]
