PM RANT: Launching anything in a big company is an "impossible task"...
Someone told me that it is an issue that can be solved by having high agency but it is exactly the thing that is penalized first. You can only affect the locus of your influence but when you need to get work done collaboratively it is mind numbing work.
You need to sell, sell and sell. Not the right ideas always win but the loudest guy who is really chummy with the founders. Most founders can't do any better because it serves their ego. Doing things right means accepting that your throughput of ideas based in gut call is bad for the company. Having a system where meritocratic ideas win while "smart" show-sha people who are all talk and no show are fired straight up.
I have myself witnessed the death of culture when the inner circle does as what they want to, and soon the it turns very toxic for everyone involved. I can tell you that right now I am pretty much sure that 4 people will leave within 1 year, even if they were offered a 100% hike.
High agency means that you can only do the best with the cards that have been dealt to you. But even with high agency you cannot expect to solve big problems that extend beyond your scope of responsibilities.
