The time unit used by PBO is the half-yearly "activity cycle" in which every police station decides on 10 objectives to meet. Six of these objectives are chosen by the police station's senior officers, two by the police station's commanders at sub-district level, one by a commander at the district level, and one by the National Commissioner. Each objective is quantifiable and, at the end of the activity cycle, the police station's achievements can be scored and compared to scores in previous cycles. A major strength of the PBO approach is that it empowers police station personnel to meet their objectives in accordance with threats and weaknesses they have identified in their specific jurisdictions. The Israeli police service believes the PBO approach will be effective as a long-term realignment and reorientation of policing services. 1 table and 2 photographs
