Demo Narrative​

Problem Statement​

"Traditional S&OP is reactive. You wait for demand to change, then react."

Key Question​

"WHY did demand spike on March 15th? Why the drop in July?"

Solution​

"ChainAlign discovers demand drivers through external factors: weather, policy, economics."

Proof​

  • Temperature correlates with demand (r=0.72, 95% confidence)
  • Policy changes drive routing decisions (45-day response time)
  • Economic indicators predict supplier capacity

Differentiation​

  1. Discovers vs. Assumes - Finds actual correlations from your data
  2. Explains vs. Black Box - Shows reasoning transparently
  3. Integrates - Combines weather, policy, economics, internal data
  4. Transparent - Full audit trail of decisions
  5. Real-Time - Live dashboards with freshness tracking
  6. Extensible - Can add custom data sources

Call to Action​

  • "Let's start with your pilot data"
  • "What SKUs would benefit most?"
  • "We can discover correlations specific to your business"
