Becoming a Change Artist is not bad, but it’s also not in the top three books that I’d recommend from Gerald Weinberg.
Read it if you have three to four hours to spare, and you’re interested in the dynamic of change in an organization. Don’t read it if you’ve heard great things about Mr. Weinberg and want to see what all the fuss is about.
Start instead with Becoming a Technical Leader or The Secrets of Consulting. You don’t need to be an official consultant to benefit from The Secrets of Consulting. Most of consulting involves facilitating work among groups of humans, and that’s probably a big part of your job even if you don’t want to admit it.
