There’s a nice interview with Carmen DeArdo, DevOps technology leader for Nationwide Insurance, over at The Enterprisers Project. The whole thing is worth reading but here’s one highlight:
So a key learning is that while technology is great, if you don’t have an efficient end-to-end process that provides continuous visibility of the work as it progresses and also reduces variance, technology will only provide limited value to improving speed and efficiency of what you deliver to your customers.
This is an ongoing theme around DevOps. Modern open source toolchains do matter. But so does having processes that enable automation and provide continuous rapid feedback loops. (And, as Carmen mentions elsewhere in the interview, having the right people and culture is key as well. He says that "forming agile teams is a great way to start."
