Answer: bureaucratic characteristics
Step-by-step explanation:
From the information given, we can say that ZipCar lacks bureaucratic characteristics. A bureaucratic organization is an organization with several layers of systems and processes and this brings about complexity and delay in decision making as it is hierarchical.
Since ZipCar's decision making does not follow a strict chain of command, and the first-line customer service agents have the authority to make decisions without management approval, this shows that the organization lacks bureaucratic characteristics.
