## Introduction

The C3 AI Demand Forecasting application helps organizations predict future demand for products and services with high accuracy. By leveraging time series analysis, machine learning algorithms, and external factors, the application enables businesses to optimize inventory, reduce costs, and improve customer satisfaction through better planning and resource allocation.

## Key Features in Version 8.7

* **Improved Forecasting Algorithms**: Enhanced ML models for accurate predictions
* **Hierarchical Forecasting**: Predictions at different product hierarchy levels
* **External Factor Analysis**: Incorporate key external variables into forecasts
* **Basic What-If Analysis**: Test simple scenarios and their impact on demand
* **Model Comparison**: Compare performance of different forecasting models
* **Forecast Insights**: Basic insights into forecast drivers
* **Standard Dashboards**: Visualizations and standard reports
