Why is the Policy Governance model said to be rigid?
Because it is! If you boil down any field of endeavor to its basic, irreducibly minimum principles, those principles are quite fixed. Holding them fixed means all other factors can be allowed to vary as a given board wishes. Engineering principles are very rigid, but if faithfully observed can be the foundation for an untold array of bridge designs. Any generic theory consists of an inflexible few tenets upon which can safely be built an uncountable array of unique structures and processes.
