Why CI is BETTER Than Feature Branching

Continuous Integration and Feature Branching are both very popular ways of organising work in a development team, but they are mutually exclusive for most cases. This is counter to what many, maybe most people think. In this video Dave Farley explains the difference and why the two are largely mutually exclusive and why CI is technically the better approach.

Software engineering, any engineering, is all about trade-offs, the trade-off at the heart of CI is that to avoid conflicts our aim is to integrate our code with that of our co-workers as close to “continuously” as we can, that means that we can’t afford to wait until we are finished. If we have two, or more, copies of information and begin changing them, the copies will diverge. At some point they will reach a point where they are incompatible with one another, and so bringing them back together gets increasingly difficult. CI was invented to fix that problem this video explains how it does that.
