The two fastest way to implementing a bureaucracy in my opinion are centralizing decision making and implementing process.

Centralizing decisions moves the person implementing something as far away from the person with power to change it as possible. It's why your bank teller just looks at you and says "there’s nothing I can do". It means the people on the ground with the knowledge of how best to do something are being ignored and disempowered to make good changes. You can try all sorts of things to fight that, spend time talking to the do'ers, put in a suggestion box etc. But why not just give them the power to change things and rather use intelligent oversight? If it's because you can't trust them, then you have a bigger problem, and one that won't be fixed by continuing to not trust them.

As for processes, the Netflix Culture Deck puts it well (https://jobs.netflix.com/culture). Paraphrasing badly, if you want to do something the same way every time, processify it, if you want people to keep doing it better, let exceptional people be exceptional. Process is a way of telling people "how" to do something instead of just "what to do". It encourages less thinking. Worse, if it's enforced, it disempowers people from optimizing or inventing. My suggestion, write down the objectives, why they're needed, and who can help you with them, then let smart people figure out how to go about getting those done most appropriately for the situation.

Fight organizational atrophy!
