To be sustainable, practices must have step-by-step systems in place. A practice that depends solely on the knowledge and commitment of the doctor and staff is not sustainable. However, if excellent systems have been implemented, the doctor and team can simply follow the systems as they go through the day. There will be exceptions, of course– situations that the systems don’t address. But with proper planning, these will be minimal. Overall, the systems-driven office operates smoothly, efficiently and sustainably.
