Segmentation

Decision model

How it works

Segmentation gives teams a named way to move users and customers through useful lifecycle moments. In the Marketing Refs graph, it links definitions to adjacent metrics, workflows and operating choices instead of leaving the term as isolated vocabulary.

Key takeaways

• Use Segmentation when the decision depends on activation, communication and customer progression.
• Pair Segmentation with related concepts before changing strategy, budget or execution.

Where it is used

• Lifecycle & CRM planning
• Campaign review
• Team alignment
