The idea that you can scale agile is false. It's fake. Agile experts didn't say how to do it because it can't be done. They put everything they knew, as clearly

The idea that you can scale agile is false. It's fake. Agile experts didn't say how to do it because it can't be done. They put everything they knew, as clearly as they could, in the manifesto. And then they described themselves. And almost all of them were consultants. They found that delivering software frequently to their customers worked better than any alternative. If you can do that, you can do agile. It doesn't matter if your customers are internal or external - internal might be better, because you can work with them more regularly.
