Why handoffs are usually a symptom, not a stage

Teams usually notice handoffs when work starts bouncing backward: a design cannot support real data, an implementation misses an important state, or a release solves the ticket without solving the customer problem.

Adding a longer specification can make the transfer clearer, but it does not restore the shared reasoning that disappeared before the transfer began. The documentation becomes a wall rather than a bridge.

Handoffs become expensive when disciplines are organized around separate definitions of done. Design completes screens. Engineering completes tickets. Product completes a roadmap. Nobody owns whether those outputs form one coherent experience.

The practical correction is to bring the people making consequential decisions into the same review loop, from framing through release. This shared ownership ensures that every discipline is working toward the same outcome.

Keep specialist ownership, but share context. A designer should not prescribe architecture, and an engineer should not silently rewrite product intent. Both should be able to see the constraint, explain the trade-off, and agree on the consequence. This creates a culture of mutual respect and better product outcomes.
