Chapter 76 — Retail & Consumer Goods

Overview

Retail and Consumer Goods industries operate on thin margins with high transaction volumes, making AI optimization critical for profitability and competitiveness. Success requires balancing customer experience, operational efficiency, and margin optimization across increasingly complex omni-channel journeys. AI enables retailers to deliver personalized experiences at scale while managing inventory, pricing, and supply chain with unprecedented precision.

The industry faces unique challenges: seasonality and trend volatility, fragmented customer touchpoints, privacy regulations for personalization, and the need for real-time decision-making at massive scale. Modern retail AI must serve both digital and physical channels seamlessly while respecting customer privacy and maintaining brand equity.

Business Challenge

• 60% of customers only shop one channel
• Personalization inconsistent across touchpoints
• Email campaigns generic, low engagement (12% open rate, 1.5% CTR)
• In-store associates lack customer context
• Mobile app underutilized
