Business models and systems do not exist for their own sake. Rather, they are designed to help your practice achieve its goals. Before you adopt any new system for any aspect of your practice, define the goals and write down the specific objectives you expect the system to achieve. Bear in mind that systems need to be easily understood by team members and by those who join the practice later on. It is important to understand that economic changes, governmental mandates and other factors beyond your control may make it necessary to reassess the way each system operates on a regular basis.
