A human resource professional may engage in all of the following activities EXCEPT?

The activity of developing new products typically falls outside the primary responsibilities of a human resource professional. Human resources is primarily focused on managing and supporting the workforce within an organization. This includes conducting interviews to select suitable candidates, offering training sessions to enhance employees' skills and performance, and managing employee relations to ensure a positive workplace environment.

In contrast, product development is usually the domain of product managers, engineers, or marketing teams who focus on creating and improving the organization's offerings. Therefore, while human resource professionals play a significant role in shaping the workforce and organizational culture, developing new products does not align with the core functions of human resources.
