REFERENCES
Different industries gave me perspective, not a universal answer.
The value of experience is not that every problem looks familiar. It is that you learn to ask better questions before assuming you already know the cause.
WHY VARIETY HELPS
A bottleneck rarely wears the same clothes twice.
In one company it is slow approvals. In another it is founder rescue. Somewhere else it is an ownership dispute caused by unclear authority. Experience helps me ask better questions earlier; the answer still has to come from your business.
