Understanding the impact of each of your deployments is crucial, especially as they become increasingly frequent. Chances are, your team is either aiming to increase shipping velocity or has already started deploying "continuously" (which is to say, multiple times a day). The biggest tech teams at the likes of Amazon and Google deploy thousands of times daily, and Atlassian has found that 75% of enterprise DevOps teams call deployment frequency their most important success criteria. And while CD comes with a host of well-established benefits, it also introduces a heightened risk of introducing new errors and issues.
