Which system is NOT used to track and manage work and costs?

Job performance systems typically focus on measuring and evaluating employee performance and productivity rather than specifically managing work tasks or costs associated with projects or operations. While they may contribute to understanding employee efficiency and outcomes, they do not inherently track work assignments or the associated financial aspects.

In contrast, service request systems are designed to manage incoming requests for work, helping to prioritize and allocate resources efficiently. Asset inventory systems keep track of physical assets, including their status and associated costs, facilitating better management of resources. Maintenance management systems specifically focus on the upkeep and repair of assets, including scheduling work and monitoring costs related to maintenance tasks. Therefore, while job performance systems provide valuable insight into employee efficiency, they are not utilized for directly managing work and associated costs like the other systems mentioned.
