As Marc Andreessen said in a recent Joe Rogan podcast the goal of vision is to “form and reinforce the cult”. You need to trick employees into believing in something. Cults and cult leaders are exceptional examples for corporations to learn from.
Isn't exactly the cult aspect that prevents you from making real improvements and grow? You get no critical feedback, no worthwhile reflection on what works and what does not. So you do less adjustments and cannot reach the optimum as fast.
