In rudderless large organizations, ideas just have to stand out compared to entropy.
Someone working with intention can likely find little ripples to accentuate into larger waves to ride, because there isn't a strong opposing force, just randomness.
A very different situation: the bottom-up entropy of any large organization… but with a very empowered senior lead with a specific, and perhaps on some topic wrong, perspective.
Those are way, way harder to make good things happen without convincing that key person.
You can't find waves to surf to good outcomes, because they all emanate from that one person's perspective.
