When delivery slows down without a clear cause, guessing becomes the default strategy. Before you decide what to change, you need to understand what is actually shaping outcomes today.

Nothing breaks. Nothing explodes. Delivery just becomes harder than it should be. Teams stall not because of scale, but because of structural ambiguity.
