I think back to the early 2000's, and there are other factors in play as well. Back then, I worked with a team of engineers that stayed together for over 4 years. In that time, we did not have Project Managers telling us to do daily standups. We met as an engineering team. We often would go days without having a formal meeting. But, software was different then as well. Everything is interconnected now. One team dropping the ball affects countless other teams. Deployments were whenever we felt a new one was due or at a multi month cadence. Did this introduce problems, yes, but at the same time, they came in controlled release cycles. Nothing against CI/CD and continuous delivery, but the hamster wheel has gotten to a point where we have to release all the time. Corners are cut on everything, and testing is given lip service. At this point, I am a manager, and SCRUM stresses me out. Either let us work from a queue, or give us a project with a deadline. Give me back a stupid gant or pert chart. At least then it was, is this done to allow XYZ, not we are going to accomplish this in the next 2 (arbitrary) weeks. So much more to say, but I am toast. |
Just to call it out: Having CI/CD doesn't mean you have to do all these things, or do scrum. It's imho just good engineering practice. I have it in my side projects, and I've had it at work on a Kanban-driven team (as well as on scrum).
It removes disputes over build process (eg, nobody can ever say "well, it complies on my machine"). It is a form of build/deploy documentation. It removes bottlenecks ("only Tom knows how to deploy that service, but he's on vacation") and stupid mistakes ("whoever deployed this last did it wrong and left a bunch of old files around").
I also have found deploying regularly is stress-reducing. For one, with CD the development environment is running the same steps, and we know it works because we do it dozens of times a week. The longer it's been since last prod deploy, the less confident we can be it'll go smoothly, whereas when it gets deployed every few days it becomes a non-event.
When something breaks, having only 1 or 3 changes makes it really easy to figure out why. Recovering after a big release with 40 PRs in it is absolutely painful.
None of this means you have to release everything on a regular schedule (like a sprint). You can still do long running branches or feature-flag things off, Just try not to go too long without deploying something.
