Which of the following is a common task for an administrative assistant?

Organizing files and data is a common task for an administrative assistant as it plays a crucial role in ensuring that an office runs efficiently. Administrative assistants are often responsible for maintaining filing systems, both physical and electronic, which can involve sorting, labeling, and storing documents appropriately. This task helps in managing information effectively, making it accessible when needed, and ensuring compliance with data storage regulations.

In contrast, developing company strategies typically falls within the realm of upper management or strategic planning teams rather than administrative roles. Similarly, negotiating contracts is a specialized function often handled by legal or procurement professionals who have expertise in negotiations and contract law. Conducting performance reviews is usually the responsibility of supervisors or managers, as it requires a deeper understanding of employee performance metrics and management practices than what is expected from an administrative support position. Thus, organizing files and data aligns well with the administrative assistant's role and responsibilities.
