Business Forecasting

Build the foundation for useful forecasting by defining exactly what must be forecast, why the forecast exists, who will use it, and when the decision must be made. You will specify the target, horizon, frequency, granularity, information set, data preparation rules, assumptions, benchmarks, ownership, and forecasting workflow while learning how to prevent data leakage and false certainty.

Learn how to understand a time series before choosing a forecasting method. You will identify level, trend, growth, seasonality, calendar effects, cycles, events, outliers, structural breaks, lag relationships, autocorrelation, and decomposition so the model reflects the actual behaviour of the business series rather than forcing every pattern into one method.

Start forecasting with methods whose logic can be understood and challenged. You will build mean, naive, and seasonal-naive benchmarks, then use moving averages, weighted moving averages, and simple exponential smoothing while learning how window length, weights, and smoothing responsiveness change the forecast.

Extend smoothing methods to business series that contain persistent direction and recurring seasonal behaviour. You will work with Holt's trend method, damped trend, seasonal effects, Holt-Winters additive models, multiplicative seasonality, and ETS thinking while learning when different structures are appropriate.

Learn how to decide whether a forecasting method is genuinely useful rather than merely fitting historical data. You will calculate forecast errors, diagnose bias, compare MAE, MSE, RMSE, MAPE, WAPE, and MASE, design chronological train/test evaluations, run rolling-origin backtests, assess different forecast horizons, and complete a weekly-orders forecasting capstone.

Connect forecasting to the business variables that may help explain future outcomes. You will build simple and multiple regression forecasts, incorporate calendar and promotional effects, distinguish prediction from causality, handle predictors whose future values are unknown, use explicit driver scenarios, and combine regression with time-series error structure.

Move beyond single-number forecasts and represent the range of outcomes the business may realistically face. You will work with forecast distributions, prediction intervals, quantile forecasts, asymmetric business costs, pinball loss, interval coverage, calibration, scenario forecasting, stress ranges, and decision-ready uncertainty communication.

Learn how to forecast situations where ordinary methods are not enough. You will handle intermittent and sparse demand, new products with little history, structured analogies, product and geographic hierarchies, grouped forecasts, reconciliation, coherent totals, and forecast combinations or ensembles without creating false confidence.

Turn forecasting from a model into a controlled business process. You will use structured judgment, govern forecast overrides, calculate Forecast Value Add, design forecasting cadences and data cut-offs, maintain forecast vintages, monitor bias and drift, trigger reforecasting appropriately, and govern AI or machine-learning forecasts through validation, lineage, versioning, monitoring, and human accountability.

Bring forecasting into the decisions it is meant to support. You will connect forecasts with capacity, inventory, revenue, cash flow, cross-functional planning, executive communication, decision thresholds, and operating policies while keeping forecasts, judgmental adjustments, targets, and final plans clearly separated. The course concludes with a complete enterprise business forecasting capstone.
