Effective organizations identify new customers and desired products and services. They use their evaluation processes to continually update and improve their concepts of what business they are in, who their customers are, and how to better deliver quality products and services. If your agency management system employs these processes, and takes them seriously, any of the systems listed in the first paragraph might be used to describe your management system. If any of the major pieces or processes mentioned above are missing in your system it will probably decrease your agency's effectiveness. But, that's what evaluation is all about, a way to learn and change to improve.
Every agency has management and decision making systems.
Total Quality Management, Comprehensive Management Systems, Kaizen Management, and other currently popular management systems alter or replace existing processes within fish and wildlife agencies in as much as the systems change the primary focus toward including customers at levels previously not undertaken by agencies. Each of the systems use similar means to achieve this shift, but none probably have all the right tools. The primary issue for an agency is whether they will commit to an ongoing change process and a fundamental shift toward broader participation.
