# Flexible GTM Boundaries

The practice of defining **fluid guidelines** for when a customer should transition from one go-to-market model to another, as opposed to using **rigid, static segmentation**.

Because organizations operate multiple GTM models simultaneously — [[concept-digital-first-gtm]], [[concept-hybrid-gtm]], [[concept-relationship-led-gtm]] — they must define **which model engages which customers for specific tasks**.

**Rigid segmentation often fails** ([[claim-rigid-segmentation-fails]]) because it does not reflect actual, dynamic customer behavior, leading to:
- **overlaps** → conflicting coverage
- **gaps** → incomplete coverage

Flexible boundaries let organizations adapt to a customer's evolving needs across the adoption lifecycle, moving them **seamlessly** between self-service and human-assisted models. This customer-evolution dynamic is one of the [[framework-adaptation-triggers]]. See the supporting [[quote-rigid-segmentation]].

> **Enrichment:** Aligns with **dynamic / segment-of-one segmentation** and lifecycle orchestration — customers move between segments over time rather than staying fixed in one bucket, a common response to the limits of static ICPs and fixed routing rules.
