The Architecture of Flow: Comparing Cadence and Curation in Service Sequence Design
Every service sequence is a promise. When a user signs up for a newsletter, starts a free trial, or books a consultation, they implicitly agree to follow a series of steps. The designer's job is to make that series feel inevitable—not forced. Two philosophies dominate modern sequence design: cadence and curation. Cadence sequences march to a fixed beat: send email on day 1, day 3, day 7. Curation sequences adapt: send the next step only when the user performs a specific action. Both have passionate advocates. Both can fail spectacularly when applied to the wrong context. This guide unpacks the architecture behind each approach, compares their strengths, and offers a framework for choosing—or blending—them in real-world service design. Why Sequence Design Matters More Than You Think Most service failures are not product failures. They are sequence failures.
