What is DEEP Backlog?

DEEP Backlog is a high functioning product backlog.

  • Detailed appropriately: Backlog items should have detailed relevant information for the cross-functional team. Backlog items are tokens promising a future conversation.
  • Emergent: Product backlog evolves and new stories can be added/removed as new information arrives. It behaves like a scrum artifact.
  • Estimated: A product backlog tool blueprints development resources. So every upcoming item must be estimated for the time it will take to complete. Estimate precision depends on the item’s priority.
  • Prioritised: Items are prioritized by their value and strategic purposes that they serve. A high value means high priority.
