The Policy Quality Framework describes the key characteristics of quality policy advice, as well as the ‘enablers’ of great advice, like considering multiple perspectives, good commissioning, quality assurance processes and work planning.
It is one of three improvement frameworks co-designed for and by the policy community in New Zealand to help government agencies improve their policy quality and capability.
It includes several policy assessments for different stages of the policy cycle and describes some "acid tests" to evaluate the quality of policy.
