Salesforce has been undergoing a (sometimes painful) DevOps transformation for almost a year now. Along the way we have had a number of successes, and a number of failures. I'm proposing an ignite talk in the style of Todd Parr's "Do's and Don'ts" and "Underwear Do's and Don¹t's" (http://www.amazon.com/dp/0316908061/ref=rdr_ext_tmb) books for 3 year olds. With the 20 slides, we can cover up to 20 best/worst suggestions for practicing DevOps.
DO: Adopt the CAMS model for explaining to your executives and others why we're doing what we're doing and what are the components of a successful transformation
DON'T: Worry about the tooling when you could be worrying about the culture. Cultural change is what it takes to be successful in your transformation and at a big company like salesforce.com, cultural change is HARD. (plus, you might make John Willis take his C from the model and go home)
DO: Get the Ops team involved early in the process. DevOps needs to be driven by and participated in by both organizations. If one side is preaching to the other, you won't have DevOps and you will probably be in worse shape than when you started.
DON'T: Get Ops involved earlier by allowing them to create a "Front Door Process" where you need to fill out a form when you start on any development project and submit that to Ops to get their approval (yes, this actually happened)!
