in order to analyze contextual inquiry data either affinity diagrams can be created (together with a group of people) or an expert reading of the data can be made.
I am the only user experience consultant hired so far and most of the other consultants are hard core developers. I have decided to analyze the collected data, in a more traditional kind of analysis. (expert reading)
When more UCD practitioners are hired, I would like to start using the affinity diagram method.
