When managers determine which current employees are available for promotion or transfer, they will most likely use ___.

When managers are assessing which current employees are available for promotion or transfer, they will primarily utilize skills inventories. A skills inventory is a detailed record of an employee's competencies, qualifications, and experiences. This comprehensive tool helps managers to match employees' skills with the requirements of open positions, ensuring they consider the right candidates for advancement or relocation within the organization.

The effectiveness of a skills inventory lies in its focus on the actual capabilities and skills possessed by employees, rather than just their current roles or previous performance metrics. It provides a broad overview of an employee's potential to succeed in different roles, thus aiding in making informed decisions about promotions and transfers.

The other options, while useful in different contexts, do not serve the same purpose as skills inventories in this specific scenario. Job descriptions outline the essential functions and responsibilities of positions but do not detail employees' current skills. Performance reviews provide insights into an employee's past performance but may not capture all of their skills or potential. Employee surveys gather feedback on job satisfaction or organizational climate but are not designed to assess individual skills relevant for promotion or transfer considerations.
