Elicitation methods

We routinely use a broad range of different elicitation methods for different purposes.
We don't use interviews, questionnaires and focus groups very much, because those methods aren't able to access the various types of semi-tacit knowledge properly, and they're worse than useless when dealing with truly tacit knowledge.
The diagram below gives a brief overview of the different types of knowledge. Our full framework of knowledge types contains several sub-divisions of each of the three main types below. Interviews, questionnaires and focus groups are only able to access explicit knowledge consistently.
We've written in more detail about this framework, and about choosing appropriate elicitation methods, in this article, which contains references to further resources.
