I'm a test strategist, based in London. I work independently, for multiple simultaneous clients, in a wide range of businesses. Some of my clients are agile - I've spent perhaps two years of the last six on agile projects, some great, some less than great. I'm particularly interested in the way that Exploratory testing fits with the Massive Confirmatory Testing typically used on agile projects.
As with many consultants, I have a sideline in talking and teaching. Most recently, I gave the closing keynote at EuroSTAR, on "Becoming Agile; adapting testing to an agile environment". You can hear the talk here: http://www.workroom-productions.com/EuroSTAR2008.html . I teach exploratory testing and software diagnostics - for which read "How to find bugs and debug systems".
