Final answer:
Job specialization refers to employees focusing on specific tasks where they have an advantage. Making employees responsible for specific customers doesn't define job specialization but relates to customer relationship management. Hence, the statement about job specialization in this context is false.
Step-by-step explanation:
Job specialization involves employees focusing on a particular aspect of the production process where they have an advantage due to their unique skills, talents, or certain situational factors such as geography. This concept is often seen in businesses that divide tasks to enhance efficiency and productivity.
For instance, a restaurant might have different staff for cooking, serving, and management. However, making employees directly responsible for specific customers and having them communicate directly with those customers is not job specialization; it rather involves aspects of customer relationship management or account management. Therefore, the statement about job specialization in the context of employees being made directly responsible for specific customers and communicating with them is false.
