When making a transition to agile, it’s important to get a common understanding of what you’re trying to do, of how things are currently done, and of the definition of done. In a value stream analysis, you can identify where major chunks of time are being spent (and why), and then start prioritizing based on value.

When we are presented with a decision, the subconscious determines what we’re most emotionally comfortable with, then fills in the gaps to justify choosing it. In other words: Our brains lie to us. Then how can we ever get out of our comfort zone? Believe in change and take an agile approach to incremental adoption.

Is your process for pull requests compromising your team's agility? You can structure your changes in a way that facilitates more rapid feedback, but even then it is still possible to have a slow integration time if people don’t review pull requests promptly. Mechanics are part of it, but culture also matters.
