If you’re interested in discussing more about continuous delivery, there’s an umoderated continuous delivery mailing list on Google Groups.

A note on contacting me

The best way to reach me is by email at humble@acm.org, but unfortunately due to the large amount of email I receive I’m afraid I can’t guarantee a response. To increase your chances of a reply try a query that is short and has a simple yes/no answer. In particular, I have learned from experience not to offer advice over the internet. If you’re not sure how to proceed, I have two pieces of general advice: first, work from first principles. Second, apply the scientific method: Mike Rother’s Improvement Kata is an excellent resource.
