If you ingrain a culture of "actions have consequences" you disincentivize actions. This is why everyone is fine with letting nowhere projects run ahead, and adding to technical debt, or just keep on incurring running costs instead of cutting them. "If I don't make a choice, it's not my fault". It's much better to establish a culture of "try doing good things, and we're in this together". If you trust your colleagues and are good at recruiting, you'll get a lot more done. I don't know if I have any specific tips and ideas for post-mortems as it usually... "depends".
