Today I met fellow blogger High Tech Hick. The course was on information audits, and HTH, a content architect, had lots of great ideas for me.
One phrase she used which I had never heard of before: "proof of concept". It's essentially a test or pilot phase of a project to see if certain assumptions will possibly work. It is used as an initial stage before putting forward a proposal to run a full project. It's a way to move cautiously into a major project.
