Their duties include monitoring the assembly line, identifying defects, documenting issues, and sometimes testing products for functionality and safety. They play a key role in maintaining product consistency, reducing waste, and upholding company standards.

Effective communication, problem-solving, and teamwork are essential soft skills for this role. These skills and qualifications ensure product consistency, minimize defects, and contribute to efficient and safe manufacturing operations.
