Continuous Delivery fundamentally changes the Economics of Software Development
By taking a manual, error-prone and infrequent process and making it something that is automated, reliable and safe, Continuous Delivery makes it economically feasible to deploy frequently, even multiple times per day.
Once the pain and effort is removed from deployment, you can deploy in small batches, even a single change.
This reduction in batch size in turn drives higher quality, enables more innovation and experimentation, and much faster time-to-market.
