This guide for administrators, based on the best practices found in 25 states, proposes a prototype system within which a more humane and sensitive delivery of services at the agency level can be efficiently achieved for children and their families. System goals for assisting clients are described, and the objectives which must be met to achieve those goals are listed. Characteristics of the system are described in terms of inputs to the system (e.g., clients and personnel), system functions (community outreach, reception, emergency service provision, diagnosis), standards the system must satisfy, feedback required by the system, and the system's results in terms of service to clients, agency outcomes, and information outputs. The prototype also specifies requirements for effective operation; these are grouped into four categories: resource management (e.g., staffing), general management (e.g., office administration), self assessment and planning, and information processing (with emphasis on case records). The final section briefly discusses implementing the system. Diagrams are included to illustrate system structure, operations and relations with outside agencies and the community. (BH)
