Yes. Read Accelerate and read the State of DevOps reports from 2017 through 2022. The reports have the data and explain their methodologies for evaluating said data. It's all there for you to consume.
Is there anything that will satisfy you or will anything that anyone presents be dismissed? I could spend days hunting out the evidence and you'd start question whether it's peer reviewed, or if the peer review was stringent enough, etc.
Meanwhile the rest of the world is moving forward without you.
Read any book on the subject, they’ve done the research for you. The Phoenix Project, The State of DevOps Report.
Spend some time in companies that move slow vs fast and you’ll see the difference in their success first hand. You’ll see the metrics on their incidents and severity and customer satisfaction with them.
Oh, and the fact two companies mentioned (Google and Facebook) are two of the most successful companies on earth.
See my comment elsewhere taking “people are the product” out of this conversation.
Facebook and Google and like companies do not care if they piss users off. They churn features constantly, break people’s flows on a regular basis, A-B test features so different people get different experiences.
They get away with this because the “users” aren’t users, they and their data are the product. You pay nothing to use their services, and you get what you pay for.
Can you point out specifically where someone says releasing up to 20x a day into production for a paid platform is a good thing?
I am not talking about the capability. I grant being able to release quickly and often is desirable. I question the wisdom of actually releasing multiple times a day into production as a best practice. In my mind it is highly inefficient and offers too much churn for users (eg exactly my experience with Facebook, a chaotic broken product that changes hourly and makes people feel like the product t is gas lighting them).
Read above: Accelerate and The State of DevOps are two reads.
From experience, across teams, we deploy probably 20x a day and we're actively trying to deploy more often. Our customer NPS scores are pretty high and our change failure rate is low. We're also a very successful B2B SaaS.
