Which tool is NOT commonly used for training staff?

The correct answer is that physical fitness sessions are not commonly used as a tool for training staff in the context of change management. While physical fitness sessions may enhance employee well-being, boost morale, or improve team bonding, they do not specifically provide the knowledge or skills needed for job performance or understanding the changes being implemented.

In contrast, documentation serves as a resource that outlines procedures, policies, and guidelines to ensure employees have access to necessary information. Subject matter experts bring expertise and insights critical for effective training, often leading sessions or providing mentorship on specific topics. Quick card guides are handy reference tools that summarize key information or steps, facilitating quick retrieval of knowledge during tasks.

Each of the other options is directly aligned with providing essential training and skill development for staff, whereas physical fitness sessions are generally unrelated to professional training objectives.
