The point is to decouple deployment from activation so that we can learn for free without affecting our customers' experience.

When you look at continuous deployment and continuous delivery, we're putting code out there faster. In some cases, code is on a unit test, and then committed, and then through static code analysis, integration tests, fast regression stack and—Bam! Production! Well, why do we do that?
