Shadowing is primarily used to

• A. Teach the worker
• B. Learn by watching a skilled worker
• C. Schedule the shift
• D. Replace the worker

Answer: (B)

Shadowing is a learning approach where a trainee follows a skilled worker to observe how tasks are performed. This method is most effective for learning by watching because it shows the actual workflow, techniques, tool handling, the order of steps, and safety practices in the real work environment. In additive manufacturing, shadowing lets a learner see how a printer is set up, how materials and parameters are chosen, how the job is monitored, and how post-processing and quality checks are done, helping them internalize the correct procedures through live context. It isn’t about scheduling shifts or replacing workers; it’s a training method that builds practical understanding under supervision, often followed by hands-on practice.
