What do you see as the reasons for the military defeats of the participants in the fourth anti-Napoleonic coalition?

The main reasons for the military defeats (at Friedland and Austerlitz) of the troops of the coalition, concluded against Bonaparte, were the inconsistency of actions, separate administration and the intervention of the emperors. There was no general command, the Russian troops fought desperately, the Austrian units behaved passively. The British and Prussian armies practically did not take part in the hostilities. Each army was commanded by its own generals, who did not interact well with each other. Emperor Alexander intervened in all aspects of the management of the military, and was purely civil.
