Best Care Hospitals have been long providing health care since 1985. The first Best Care Hospitals is situated in Chicago and it's branch in New York. With increased profits, Mark the CEO of the hospital, has decided to open three other branches in Texas, California, and Atlanta. However, the main problem in opening three other branches is the lack of central administration of all the five branches. This administration is required because the Chicago branch also has a Research and Development center, which will supply information to the newly opened branches. To provide an optimal and long-term solution to the abovementioned problem, Mark has assigned this task to me, the system administrator. With respect to the current requirements of the organization and the future anticipated requirements, I need to plan the forest, a new domain structure for all the branch offices, and the number of organizational units in each domain. That is to say that I have to plan the organization's new domain-based structure.
