It’s a bit counterintuitive but I think it’s a good point that all the efforts to more and better coordination are harmful. We should have less coordination which will inevitably lead to more work between teams, but that is work you should be doing anyway. I think teams are in general very heavily underfacilitated.
When we change the system later, strong boundaries make those changes faster. Deep coordination makes those changes harder: the tight coupling still exists but the armies have moved on, the armies of project managers who heroically held together that initial release.
