Which of the following is NOT one of the four report types available in Smartsheet?

The option indicating "Performance" is indeed not one of the four report types available in Smartsheet. Smartsheet offers a variety of reporting tools designed to enhance project management through different perspectives. These report types primarily include Time/Fees, Expense, Utilization, and several others tailored to help users track project progress and manage resources efficiently.

The Time/Fees report focuses on tracking time and cost-related data, allowing users to monitor budgeted vs. actual expenditures. The Expense report is crucial for keeping tabs on any costs that might arise during project execution, providing a clear view of financial resource allocation. The Utilization report helps in understanding how effectively team members are being utilized across various tasks and projects.

Thus, "Performance" does not fit into the established categories of reports offered by Smartsheet, making it the correct choice as the option that is not one of the report types.
