Final answer:
The specialization of labor increases productivity through efficiency, time-saving, improved coordination, and technological advancements.
Step-by-step explanation:
The four ways in which the specialization of labor increases productivity are:
1. Efficiency: When workers specialize in certain tasks, they become more skilled and efficient at performing those tasks. This leads to higher productivity and output.
2. Time-saving: Specialization allows workers to focus on a specific task, which reduces the time needed to switch between different tasks. This results in time savings and increased productivity.
3. Improved coordination: Specialization allows for better coordination among workers. Each worker knows their role and can collaborate more effectively, resulting in improved productivity.
4. Technological advancements: Specialization often leads to the development of specialized tools and technologies that can further enhance productivity. For example, in the case of McDonald's, specialized cooking equipment and assembly lines are used to streamline the production process and increase efficiency.
