Continuous Delivery. I'm building internally used software, and getting feedback from stakeholders in the testing environment was hard work, and often impossible. We went from roughly monthly releases to deploy-when-it's-ready, and this tightened our feedback loops immensely. Also, when something breaks due to a deployment, it's usually just one or two things that could be responsible, instead of 20+ that went into one monthly release. Waaaay easier to debug with small increments.
