I once reported to a CTO whose bible was How To Influence People and Make Friends.
He ordered a migration of 4 million records to be done in a weekend because he had promised the CEO “everything would be fine by Monday” but I had told him that that plan would require 5 days to put everything in place, even a rollback.
The fact that he refused to hear me out when I pointed out the infrastructure capacity and the SQL scripts tested beforehand to arrive at my estimate made me wary of management that doesn’t understand even the basics of the technology we use.
So I think it goes a long way when CTOs are technical. They can give more realistic deadlines to reports while being able to be reasonably honest to their colleagues about estimates and progress.
