I define the quantity of service provided on the site as the number of visits that SJPD physically makes to the location address recorded in the call record. My rationale for this is that, this way,  there is some reasonable assurance that that the final determination of the outcome of the visit (recorded as a 'final disposition') will be governed by the Department's internal policy.
I define  the class of service - "community support service"  - as the service requested by the public to support them in the context of "Family Disturbance" and those that are not assessed by the SJPD as resulting in a decision to Arrest, Cite or perform any other serious criminal justice intervention. In other words, I assume that in cases where the CJPD has decided not to take adverse legal action, it is essentially acting in a community support role in essentially family related matters. I take the disposition of "R - Report Taken" as the threshold at which to select the visit for study. To be clear, I include O- Unfounded Event, G - Gone on Arrival in the study because these events suggest that they are not trivial and that these disposition codes really reflect police administration policy, not necessarily the family's context.
