What internal factor serves as the basis for hiring from both internal and external sources?

The basis for hiring from both internal and external sources is the recruiting policy. A well-defined recruiting policy outlines the organization's approach to sourcing talent and sets the framework for how recruitment will be conducted. It provides guidelines on the balance between promoting from within—leveraging existing talent and knowledge—versus seeking external candidates who may bring in new skills and perspectives.

Recruiting policy helps ensure consistency and fairness in the hiring process, aligning with the organization’s overall goals and values. It may specify criteria for internal promotions, the circumstances under which external hires are justified, and how to navigate the recruitment process to find the best fit for the organization.

By having a clear recruiting policy, organizations can effectively manage their workforce needs, ensuring that they attract and select the most qualified candidates, whether they come from inside or outside the company. This integration of various sourcing strategies can enhance the organization's talent pool and support long-term success.
