Legibility also increases the ability for a large organization to chase singular ambitious goals.

For example: software estimation is hard. It takes time, it's highly inaccurate (frequently by 2x or more), and rewarding good estimation incentives worse software.

But having deadlines helps functions like marketing and sales immensely. Marketing can plan effective launches, and sales can guide customers towards new products with minimal lag in uptake.

Lots of corporate life is like this. It's a net good if it's used to deliver a better experience to customers. It's a constant fight to make sure legibility efforts aren't being used to hoard power for personal gain.
