Mind Maps for Testing
I learned about mind maps at Thoughtworks, where they had been in use for test case management (and lots of other things) long before I arrived. The key advantage of mind maps, as Robert Sabourin points out in the article, is that “…misunderstandings and ambiguities are exposed and resolved in real time as you build the mind map”.
The article links to the Better Software feature article for November which is all about using Mind Maps in testing, awesome stuff.
