to be assigned to patrol. The weights must add up to 100%. For example, if SAPD command staff <br />feels that each performance objective is equally important, then a 20% weight is assigned to each <br />performance objective. A 35% weight was assigned by the SAPD command staff to the response <br />time to Priority 1 calls objective while a 20% weight was assigned to each of the following: the <br />patrol visibility objective; response time to Priority 2 calls objective; and, response time to Priority <br />3 calls objective. A weight of 5% was assigned to the immediate availability objective (see Table <br />8). The Priority 1 response time objective is most important to the SAPD command staff and thus <br />will hold more weight in the determination of the number of officers that should be assigned to <br />patrol. <br /> <br />Table 8 Base MAPP Input Values for Performance Objective Weights <br />MAPP Variable All Patrol Districts <br />Response Time Goal for Priority 1 Calls Objective Weight 35% <br />Patrol Visibility Objective Weight 20% <br />Response Time Goal for Priority 2 Calls Objective Weight 20% <br />Response Time Goal for Priority 3 Calls Objective Weight 20% <br />Immediate Availability Objective Weight 5% <br /> <br />Leave Percentage <br /> <br />The average number of hours (n=492 hours) taken by patrol officers for each category of leave in <br />2013 was provided to the research team by SAPD personnel. Using the value of 492 hours of <br />leave per year per patrol officer, the leave percentage was calculated. Since the data provided was <br />for all patrol officers, not specific officers, the leave rate was not calculated for each patrol district. <br />The leave percentage was 23.59% for patrol officers in 2013. The SAPD leave percentage is <br />consistent with the average of 24% established in prior staffing studies conducted by the research <br />team. <br />Two Officer Units <br />The percentage of time patrol units are staffed with two officers was also taken into account in the <br />development of the base MAPP. The use of two officer units is rare in SAPD; the value was set <br />at 2% in the base MAPP. <br /> <br />RESULTS OF THE BASE MAPP MODELING PROCESS <br /> <br />Table 9 illustrates the value for each variable used in the development of the base MAPP which <br />depicts the current state of conditions in SAPD patrol. Using the data presented in Table 9, the <br />base MAPP was able to accurately determine 36 patrol officers were assigned to District 1 in 2013, <br />34 patrol officers were assigned to District 2 in 2013, 37 patrol officers were assigned in District <br />3, and 40 patrol officers were assigned to District 4 in 2013.
