The strategy of the OCN program is twofold, to promote a multiagency enforcement response and to establish a formal mechanism whereby investigative and prosecution resources can be allocated, focused, and managed on a shared basis against targeted offenses and offenders. Critical to the OCN program's success is a shared management system to direct and administer joint enforcement resources. Each OCN project must comprise a formally organized group of participating law enforcement agencies and a management control group. OCN program components include basic, operational support, and financial investigation. Operational requirements of the OCN program are detailed, as well as application and site selection procedures and contract administration. A summary of OCN project outcomes for January 1987 to June 1990 and descriptions of 21 OCN projects are provided. The final monograph section considers program implementation experience and lessons learned. Furthermore, specific attention is paid to the role of self-evaluation in program improvements, project goals and objectives, case selection criteria, and case planning and monitoring. An appendix contains recommended model objectives for OCN project self- evaluation capability, a sample interagency agreement, and a sample case plan.
