Back to that culture challenge, now we have something we can show using the “M” for measurement. Look, our validation process passed! Time to “S” for share that success, perhaps in a dashboard that shows the build and deployment statuses. Even if you have to manually update that dashboard.
But, you say, “what about CD? This isn’t DevOps!” Perhaps you have to deal with Release Management because they only want monthly releases? That’s a different fight. Your focus is to make delivery to PROD a non-event. And since you’ve automated deployment across the non-production regions you know it’s just gonna work.
