It sounds like a Dilbert strip but it's true.
From the abstract at Physics arXiv:
The Peter Principle Revisited: A Computational Study
And another from January 2014:...Here we show, by means of agent based simulations, that if the latter two features actually hold in a given model of an organization with a hierarchical structure, then not only is the Peter principle unavoidable, but also it yields in turn a significant reduction of the global efficiency of the organization.Here is the paper presented at Econophysics Colloquium 2009 (55 page PDF)...MORE
Within a game theory-like approach, we explore different promotion strategies and we find, counterintuitively, that in order to avoid such an effect the best ways for improving the efficiency of a given organization are either to promote each time an agent at random or to promote randomly the best and the worst members in terms of competence.

Arbitrary and capricious.
That's the ticket.
