Final answer:
The new auto appraisal system is an enterprise sphere of influence system as it is used company-wide, integrates with other enterprise systems, and impacts various business units.
Step-by-step explanation:
The new auto appraisal system would likely be classified as operating within the enterprise sphere of influence because it is a system that would typically be used across an entire organization to assess the value of its fleet or inventory. Such systems are designed to standardize the appraisal process, providing consistency and integration with other enterprise-level systems, such as accounting and inventory management. In contrast, systems operating in the personal sphere are used by individuals, those in the workgroup sphere are used by small teams or departments, and interorganizational systems are used between separate businesses or entities. Factors to consider when categorizing systems include the breadth of the system's usage (company-wide versus team-specific), the level of integration with other systems, and the scale of impact (internal to an organization or extending beyond it). An enterprise system would likely be integrated with a company's broader IT infrastructure and impact most, if not all, business units.
