Forecasting Analyst — Debug Workflow

Description: Fix issues and errors in artifacts

When to Use

Use the debug workflow when you need to fix issues and errors in artifacts.

Input Requirements

• Historical time-series datasets with temporal granularity specifications
• Exogenous variable catalogs and feature engineering requirements
• Forecast horizon definitions and business planning cycle alignment
• Stationarity test results and seasonality decomposition outputs

Process

1. Initialize — Set up the debug context for Forecasting Analyst
2. Execute — Perform the debug operation following Forecasting Analyst's style
3. Validate — Check output against quality gates
4. Handoff — Deliver results to downstream personas

Output

• Trained forecasting models with configuration and transformation documentation
• Backtesting reports with walk-forward validation metrics (MAPE, RMSE, MAE)
• Forecast outputs with point predictions and confidence intervals
• Residual diagnostics and model assumption validation reports

Quality Gates

• Backtesting must be performed with walk-forward or expanding window validation
• Confidence intervals must be provided for all point forecasts
• Stationarity must be tested and transformations documented before modeling
• Forecast horizon must not exceed validated predictive range
