I’ve also heard that at least at some point the title “vice president” carried some form of regulatory meaning and was the minimum level required for sign off on some pretty basic things, but I’m having trouble confirming that and it may be wrong.
I have heard the same, although phrased as ‘the lowest position where someone is allowed to speak for the company’.
But it doesn't mean it's not title inflation just because there's a reason for it
Director is typically above Vice President in financial firms. I’m not sure I follow your reasoning.
Director = high level manager (of other managers)
“Senior Engineer” with 4 years experience.
Big west coast tech companies do seem to reserve VP for a select few. As they start to mature and their equity driven compensation gives way I’d be surprised if they don’t start to inflate titles as well.
If the title communicates incorrect information it isn’t merely a different convention; it actively causes confusion.
