This is the second in a series of posts about explicit, semi-tacit and tacit knowledge.
It’s structured around a four way model of whether people do, don’t, can’t or won’t state the knowledge. If they do state it, it is explicit knowledge, and can be accessed via any method. If people don’t, can’t or won’t state the knowledge, then it is some form of semi-tacit or strictly tacit knowledge, which can only be accessed via a limited set of methods such as observation, laddering or think-aloud.
This is one in a series of tutorials about reports. “Reports” in this sense involve respondents reporting what they’re doing or thinking, or what someone else is doing or thinking. We’ll post a separate overview of the different varieties of report.
The topic of this article is think-aloud technique, which involves getting the respondent to think aloud while performing a task.
This is particularly useful if you’re trying to find out what’s in the respondent’s mind while they’re doing a task, and for finding out about people’s reactions to a product or a behaviour that they witness. For instance, you can show people mockups of software or of a product you’re designing, and get at information which would be missed by interviews and questionnaires.
