Keep product context close
Every handoff loses a little context. A continuing engineering relationship retains the decisions, constraints and reasoning behind the system, so the next change can be made from understanding rather than archaeology.
Balance planned and unplanned work
A useful partnership has capacity for roadmap progress and for the realities of live operation: defects, security updates, provider changes and support questions. Ignoring one category eventually makes the other more expensive.
Review the direction, not just the backlog
Regularly return to customer signals, business priorities and technical constraints. The aim is not to keep every request moving. It is to make the next important change with enough context, quality and responsibility.
