Should Dan meet with Leah individually or communicate with all staff members?

In the medical unit of the Northeastern Medical Center, Leah Hernandez is an insurance claims specialist who works with one nurse, one certified nursing assistant, and one medical assistant/receptionist. The physician and the administrator are located in a separate building of the medical center. The administrator, Dan Jules, spends 3 hours a day in the clinic, from 9:00 to 10:30 every morning and from 2:00 to 3:30 every afternoon. He never varies the times that he is in the clinic.
