Well said.

I don't think you need a matrix management system, and actually kind of hate matrix management. In general (there are exceptions) I AM arguing for cross-functional teams. More like D&D teams, with Fighters and Wizards and Rogues and Clerics on the same team.

The management structure is a kind of separate topic. You can have cross-functional teams with or without matrix management, and I'd argue it's way better to have it without matrix management. But this is a complex topic and a separate one.
