The project combined transparent baseline logic, business-oriented forecasting, and scenario simulation into a planning capability for future customer development. Churn patterns were first reviewed across the customer life cycle to create reliable benchmark views before the forecasting approach was refined further. Rather than excluding unusual periods, the team explicitly reflected major disruptions such as COVID-19 and the energy crisis in the planning logic. The final output was embedded into a configurable simulation tool that allowed business users to test scenarios for customer inflow, market price levels, time horizons, and product-level aggregations.
