the.com/peter principle
everyone rises until they're gloriously bad at their job, then stays there forever.
means in a hierarchy, people get promoted based on success in their current role, not skill in the next one, so eventually they land in a job they're incompetent at and stop climbing.
from coined by laurence j. peter in his 1969 book of the same name, half serious management theory, half satire, arguing that competence gets you promoted until you hit your personal ceiling of incompetence.
