There's this huge difference in quality between execs who work in writing and execs who NEVER write _anything_ down, which is surprisingly common. In my experience it correlates closely with toxic behaviour and I don't know why it's common for senior management in many orgs to allow people to operate in this style.
Most modern companies drift toward the non-written style (effectively managing by the seat of the pants) because it has the appearance of being more effective, even when it is in fact the opposite. Business myth makes the guy who is always having meetings to appear more dynamic and effective, and is consequently rewarded by upper management.
An exec writing down minutes can also come back to bite them in the ass if there's a lawsuit or criminal investigation. Email can have retention policies. That's harder to enforce with paper, especially when it's someone's personal notes.
