A functional organizational structure groups individuals by their specific functions. All managers of different functional areas report to a director or vice president responsible for operational areas. While this structure separates functions by expertise, it can lead to silos focusing only on their area. A customer organizational structure organizes by customer type to ensure their expectations are met. In healthcare, outpatients and inpatients have different needs. A geographic organizational structure organizes by region to better support logistical demands and regional customer differences, with each region typically reporting to a central overseer. This is common for companies with customers across large areas.
