Recall that policies are grouped into components based on the way that they change. Policies that change for the same reasons and at the same times are grouped together by the SRP and CCP. Higher-level policies—those that are farthest from the inputs and outputs—tend to change less frequently, and for more important reasons, than lower-level policies. Lower-level policies—those that are closest to the inputs and outputs—tend to change frequently, and with more urgency, but for less important reasons.
