The designation of successors by the original charismatic leader, a second strategy described by Weber, represents an important gatekeeping mechanism regulating trustee roles. Selection systems based on recommendation, nomination, or reference; professional licensing, certification, and accreditation; and peer review ask trustees to reproduce themselves on the basis of either personal acquaintance with candidates for positions of trust or the trustees' ability to recognize and assess necessary qualities in their successors.
