Exhibit 3 provides an overview of the four system components. (See also Exhibits 4, 5, 7, and 8.) The factors involved in the development of the system of service are explored in more detail in the following sections. The Corporation for Supportive Housing has identified five indicators that reflect the evolution of a homeless system of service (Greiff et al., 2003). It is useful to keep these indicators in mind as the system components are considered:
- Power: Identified, designated positions with formal authority and responsibility
- Money: Routine or recurrent funding on which the activities can rely
- Habits: Interactions among the system participants to implement the activities of the system and which occur without mandates from authority
- Technologies/skills: Identification of skills in staff and services that were not previously common
- Ideas/values: New definitions for performance and success that are widely held among participants.
