External approvals were negatively correlated with lead time, deployment frequency, and restore time, and had no correlation with change fail rate. In short, approval by an external body (such as a manager or CAB) simply doesn’t work to increase the stability of production systems, measured by the time to restore service and change fail rate. However, it certainly slows things down. It is, in fact, worse than having no change approval process at all.

A dark launch sends a copy of real user-generated traffic to your new service, and discards the result from the new service before it's returned to the user. It helps to avoid regressions and test the new service under realistic load.
