The hunt for missing expectations

Jared Spool tells the story of a bookkeeper who became frustrated using Google Sheets because it didn’t have a double underline function.

To keep [usability] testing simple and under control, we often define the outcomes we want. For example, in testing Google Spreadsheet, we might have a profit and loss statement we’d want participants to make. To make it clear what we were expecting, we might show the final report we’d like them to make.

Since we never thought about the importance of double underlines, our sample final report wouldn’t have them. Our participant, wanting to do what we’ve asked of her, would unlikely add double underlines in. Our bias is reflected in the test results and we won’t uncover the missing expectation.

He suggests interview-based task design as a way of finding these missing expectations. Start a session with an interview to discover these expectations. Then construct a usability test task based on that.

I recently ran hybrid interviews and usability tests. That was for expediency. I didn’t base tasks on what I’d found in the interview. But it’s good to know I wasn’t completely barking up the wrong tree. I plan to use this approach in future.
