A manager wants to use the information in a recurring report on incomplete timesheets for the prior month to guide employee outreach. Which of the following report types is the best for this task?

A summary report condenses large amounts of data into an aggregated, high-level view, providing key metrics and totals relevant for decision-making. For guiding employee outreach on incomplete timesheets, a summary report would quickly show the count of incomplete timesheets, affected departments, or frequency, which is perfect for understanding the scope and planning interventions.

An infographic is a visual representation designed for quick understanding and broad communication, but it might lack the specific, detailed summaries needed for actionable insights in this context.

A snapshot report captures data at a specific point in time, but the term "snapshot" primarily refers to the data's temporal nature, not necessarily its aggregation or summarization for decision-making.

An ad hoc report is created for a one-time, specific query, whereas the question implies a recurring need for monitoring incomplete timesheets.
