SAFe is a bad name, becuase there's very little "agile" about it, but that doesn't mean it's bad for everyone.

What makes large, agile companies successful? The fact that each team, individually, is being agile. It's agile in parallel, not agile at scale.

The Agile manifesto makes it pretty clear that agile software development happens at the team level.

“We solve the problem of the ‘wall of confusion’ between dev and QA by enabling dev teams to do most testing on their own.”

If your goal is agility, you should be changing priorities frequently enough that planning more than one or two tasks ahead is a waste of time.

Can a manufacturing methodology really apply to other industries?

The traditional Dev/QA dichotomy is analogous to the Dev/Ops dichotomy DevOps aims to solve. The same solution can work for both.

How do you use the scientific method in your daily work?

Talking to users isn't the job of a user researcher. It's your job as a developer, product owner, UX designer, or any other product contributor.

When you can't scale down a large feature, think of it the other way around: How could you deliver this by tomorrow?

Simply put, SRE is only the operations side of DevOps.
