The primary goal of a Continuous Delivery pipeline is to increase throughput with simultaneous execution of stages, followed by early fault detection using highly automated testing. Longer delays between check-ins and releases can result from an increase in the number of quality gates, exact repetition of tests in differing quality gates, or longer sequential tests. These factors impact the time-to-resolve when a quick fix is needed.
If management expects quicker turnaround for last-minute software patches, this is inconsistent with the concept of a Continuous Delivery model. Continuous Delivery is an automated build, deploy, test, and release process -- not a means to last-minute development. Quality is important. What goes to production must be robust. Similar to a factory assembly line, a production pipeline increases throughput. It does not decrease cycle times.
