We are talking about software, and software is eating the world - but the great thing about software is that you can deploy it in different environments and monitor the results. Now of course "prod is different" but, the "difficult" bits you are talking about are all "how can we alignnincentices so that the ten big projects all land successfully and deliver in two years". You cannot. No matter how big brained you are no matter how many meetings. It's impossible.
So just integrate the whole fucking lot early, run a series of prod like data through it, build a couple of teams that run this integrations and they tell everyone the current state of the ten big projects. Everyone will align around those test rigs pretty damn quickly, and the ceo only needs to beast one team regularly to make sure they are not favouring anyone too much.
Or even better run two test rigs or theee and triangulate the results.
Expensive yes but damn it will get results.
And it removes a huge layer of "management status reports". What is the status of the ten projects? go look at each test rig.
As for "people don't want to read the open docs" - that's not what Inmean. people don't want to read the minutes of the board meeting because the decision has already been taken and their views don't matter. Democracy works differently - people will take an interest when their votes directly influence which stupid project gets ten million this year. And importantly politicians will arise internally - who will explain and advocate for certain projects amoung the voting base - they will be like FDR and gain power and be called traitors to their class.
And finally - no. aligning incentives is easy. Pay me.
