Final answer:
The manager should consider specialization and division of labor when deciding between adding new equipment or hiring more workers. Specialization leads to increased productivity and efficiency in the kitchen.
Step-by-step explanation:
In deciding whether to add a new grill and french fry machine or hire more workers, the manager should consider the concept of specialization and division of labor.
When each worker specializes in a specific task, such as baking or cooking, and focuses on what they do best, the kitchen can produce more meals in a given period of time. This is because specialized workers become more efficient and skilled at their specific tasks, leading to increased productivity.
On the other hand, if each worker tries to do everything from appetizer to dessert, it can lead to inefficiency and slower production. This is because workers may not have sufficient skills or experience in every aspect of cooking, resulting in delays and lower quality output.
