A governance model , ideally realized by policies , defines how these goals are implenented andmoni tored . Those policies can be low-level confi gurati on parameters , mid -level strategies or high-level intents and goals . Using a mix of these -policies implies translation between : top-down for realization and bottom-up for action / benefit and validation purposes .Networks and models must address multiple , diverse constituencies . Human intervention should be kept to a minimum ( oversight ) . Managenment means monitoring and repair ; not control .
