# Practitioner's Perspective
Modern SCM is viewed as a series of integrated material, information, and financial flows.
## Core Methodologies
- **Demand Planning:** Shifting from historical data to AI-driven predictive forecasting.
- **Inventory Management:** Utilizing Just-in-Time (JIT) and Safety Stock optimization to balance cost and availability.
- **Lean vs. Agile:** Reducing waste (Lean) while maintaining the ability to pivot rapidly (Agile).
## The Modern Shift: Agility and Resilience
Professionals are moving away from purely cost-optimized, "just-in-time" chains toward **Resilience**.
- **Diversification:** Reducing reliance on single suppliers to avoid catastrophic failures.
- **Digital Service Agility:** In the context of digital services, resilience means the ability to handle massive, unpredictable spikes in demand without service degradation.
- **Sustainability:** Integration of circular supply chains and carbon footprint reduction.
