Step-by-step explanation:
The statement that most top-rated manufacturing firms in North America rely on self-directed teams is generally true. Self-directed teams are groups of employees who are responsible for a complete, or nearly complete, product or service. This management strategy is often credited with a number of positive outcomes in the workplace, including increased job satisfaction, improved productivity, and a stronger sense of ownership among team members. This approach allows teams to tackle problems, innovate, and refine their work processes more effectively than in traditional hierarchal structures. It aligns with the modern emphasis on lean manufacturing and agile management techniques which a number of leading firms employ to remain competitive in the global marketplace.
