Final answer:
In hospitals, the transition from a traditional parallel structure to a service-line structure results in increased adaptation and innovation, autonomy for medical staff, and a clearer organizational structure.
Step-by-step explanation:
As hospitals transition from a traditional parallel structure to a service-line structure, several changes occur. Firstly, adaptation and innovation are encouraged, allowing for more flexibility and responsiveness in healthcare delivery. Secondly, two lines of authority are created, with medical staff becoming more autonomous from the organization. Lastly, the organizational structure becomes clearer, with a focus on specialization and efficiency in different service lines.
