Final answer:
The statement that job specialization results in jobs with a narrow subset of tasks, usually completed quickly, is true. Through specialization, workers gain efficiency and produce higher quality work.
Step-by-step explanation:
Job specialization does indeed result in jobs that include a narrow subset of tasks, usually completed in a short cycle time. This statement is true. Specialization allows workers to focus on the parts of the production process where they have an advantage due to their unique skills, talents, interests, and training. For example, assembly line workers, stylists, and doctors all benefit from specializing in their respective fields, often leading to increased efficiency and higher quality output. Specialized workers are also typically knowledgeable enough about their tasks to suggest innovative improvements, making their workflow quicker and more effective.
