Abstract
From a Venn diagram perspective, there are seven possible venues to consider when one looks at possible mixtures of services, integration and adaptation. Individually, we can have 1) a services system domain, 2) a spatially integrated system, and 3) a temporally adaptive system. When combined two at a time, we can have 4) an integrated service system, 5) an adaptive service system, and 6) a complex - integrated and adaptive - system. When all three combined, we can have 7) a complex - integrated and adaptive - service system. All seven venues are appropriately considered.
