What is reviewed by the CAO to assess personnel services?

The correct choice involves reviewing the "Need and financing" to assess personnel services, which encompasses understanding not only the necessity for certain personnel positions but also the financial implications of staffing decisions.

When the Chief Administrative Officer (CAO) evaluates personnel services, it is crucial to first determine the need for additional staff, based on workload, service demands, and strategic priorities. This analysis highlights which areas require enhanced human resources to operate efficiently.

Simultaneously, assessing financing is essential. The CAO needs to ascertain whether the budget can support the proposed personnel changes, including salary costs, benefits, and any related expenditures. Together, evaluating the need and financing ensures that staffing decisions align with the organization's overall goals while maintaining fiscal responsibility.

Other options, while relevant, do not encapsulate the primary focus of this assessment as comprehensively as "Need and financing." The availability of city personnel and considerations regarding financial and legal aspects also play roles, but they serve more as factors to consider within the larger context of evaluating personnel needs and securing the necessary funding.
