The Fellowship of the Lean Systems Society is a careful selection of thought leaders in the systems fields, based on stringent criteria–including leadership, originality and excellence, and direct contribution to the community–as well as the endorsement of the other Society Fellows.

Fellowship is permanent unless voluntarily relinquished or revoked by vote of a quorum of the other Fellows. Accepting a Fellowship indicates an intention to continue writing about or presenting on work of interest to the community. It also implies assent to the Society’s Credo.
