Final answer:
Managers use succession planning to determine which employees are suitable for promotion or transfer, as it focuses on the development of current employees and identifying their potential for future key roles in the business.
Step-by-step explanation:
When managers need to determine which employees are available for promotion or transfer, they will most likely use succession planning. Succession planning involves identifying and developing internal people with the potential to fill key business leadership positions in the company. This process includes assessing current employees based on their performance appraisals and their potential for growth, and this requires a good understanding of each employee's skills and potential which can be identified through a systematic evaluation process.
Other options such as job analysis, recruitment, and job evaluation are important HR functions but they serve different purposes. For instance, job analysis is used to gather information about the responsibilities, skills, outcomes, and work environment of a particular job. However, in the context of promotions or transfers, the focus is not on the job itself but rather on the employee's capabilities and future potential, making succession planning the more relevant tool.
