> What is the best way to reconcile these two opinions? Is it a matter of scale (i.e. personal process but enterprise chutzpah?)
It's a matter of experience. Process is defined by the boundary at which things start to fray. You can only find that boundary by running into it a few times and recognizing where it is. It gets much, much more complex as you grow in size because the fraying can happen as part of how two individuals interact. The more individuals you have, the riskier it is to assume the boundary is farther out, and thus the safer it is to constrict using process; there are interpersonal boundaries on top of your personal comfort zones.
If you don't need the habits and consistency, then you don't need them. Don't do that. Go big until you fail. Figure out why you failed. Account for it next time. That accounting is process. And probe your process occasionally to make sure it's still valid, too.
