How to Track Product Life Cycle Curves Using Replenishment & Review Data

Learn how replenishment and review data reveal the product life cycle curve in fashion, helping brands optimize inventory and timing.

Every fashion product follows a life cycle curve from launch and growth to maturity and eventual decline. The challenge is spotting where an item sits on this curve in real time. Too often, brands realize a product has peaked only after sales drop.

Data from replenishment patterns and customer reviews offers a sharper lens into life cycle management. According to Bain, brands that monitor product life cycles with replenishment data reduce overstock by up to 25%.

Why Replenishment & Review Data Matter

  • Replenishment Frequency: High restock frequency signals products in the growth phase. Declining restocks hint at maturity or decline.
  • Review Volume & Sentiment: Spikes in positive reviews suggest consumer excitement, while flat or negative reviews show fatigue.
  • Category-Specific Patterns: Basics (like jeans) may have longer cycles, while trend-driven items fade fast.

How to Use This Data

  • Early Growth Detection: Spot products gaining traction through repeated restocks.
  • Peak Identification: Cross-reference sales velocity with review excitement to find the sweet spot for campaigns.
  • End-of-Cycle Management: Detect fatigue early via negative reviews and slowing replenishment pivot to discounts before inventory piles up.

Conclusion

Replenishment and review data give fashion brands a live pulse on product life cycles. With this visibility, merchandisers can time campaigns, manage inventory, and avoid costly markdowns turning every phase of the curve into a strategic advantage.
