Six-phase sequence architecture for a Digital Twin of the Workforce system that models employee behavior during technology rollouts. Data Layer ingests workforce profiles, Behavior Modeling Engine generates personas, and AI/ML Prediction Engine forecasts adoption patterns. Simulation Engine runs scenario tests like Zoom-to-Teams migrations, while Visualization Layer renders dashboards and the Virtual Rollout Coach provides interactive guidance. This architecture helps enterprise architects design predictive systems that reduce change management risk and optimize training investments.
