What is a Product Backlog?
A Product Backlog is not a wish list, and it's not a requirements document. It's a living, ordered inventory of everything that could make your product better — maintained with intention, not accumulated by default. The difference between a well-managed backlog and a dumping ground is discipline, not tools.
Product Backlog definition
The Product Backlog is an emergent, ordered list of what is needed to improve the product. It is the single source of work for the Scrum Team. The Product Owner is accountable for its content, availability, and ordering. It is never complete — as long as the product exists, the backlog exists and evolves.
What goes in the backlog?
Most teams start with features and bug fixes, but a mature backlog contains a wider range of work types. Each type has a different priority profile:
Features
User-facing functionality that delivers value directly. Often expressed as user stories.
Bug fixes
Defects in existing functionality. Priority depends on severity and user impact — not every bug is urgent.
Technical debt
Code improvements that don't change user-facing behavior but improve maintainability, performance, or security. Invisible to users, critical for speed.
Research spikes
Time-boxed investigations to reduce uncertainty about a feature or technology before committing to build it.
Infrastructure work
Upgrades, migrations, compliance changes. Often deprioritized until they become critical — which is the wrong time.

Frequently asked questions
Is the Product Backlog the same as a sprint backlog?
No. The Product Backlog contains everything that could improve the product — it's maintained by the Product Owner and spans the product's entire lifetime. The Sprint Backlog is a subset selected for one sprint, created and owned by the Developers.
Should every backlog item be a user story?
No. User stories are a common format for feature requests, but technical debt items, spikes, and infrastructure work don't fit the user story template well. Use the format that best captures the intent of each item.
