Is it true that the Policy Governance model disallows committees?
The model does not disallow committees. It incorporates a few principles which, if used, prevents committees from becoming tails that wag the dog or interfering with the critical integrity of the board-CEO relationship. As a practical matter, boards that have had a large number of committees often end up with far fewer or none using Policy Governance. But Policy Governance does not frown on having committees, just on compromising governance by the way they are used.
