The enterprise-wide Medical Appointment Scheduling System (MASS), enabled by Cadence, will manage the appointment lifecycle, improve clinical resource management, and inform VHA management at all organizational levels with real-time business, resource utilization and demand, supply, and quality service metrics intelligence. To be successful, the MASS implementation will aim to exceed defined critical Success Criteria measurements. The implementation will address critical challenges for stakeholder and user adoption across the enterprise, seamless integration with VistA, and preserver local autonomy while introducing nationally standardized rules and workflows.
