What is Product Backlog?
A product backlog is the single, ordered list of everything that might be delivered for a product: features, fixes, improvements and technical work. It is a living artefact — continually refined, re-prioritised and pruned — with the most valuable, best-understood items at the top, ready to be worked on next.

In more depth
Order is the backlog's defining property: unlike a wish list, every item sits above or below every other, and that ordering is a series of prioritisation decisions the product owner is accountable for. Detail is deliberately uneven — items near the top are small, well-understood and ready for development, while items further down stay coarse until they approach the top, so effort is not wasted specifying work that may never be done. Regular refinement keeps this shape, and regular pruning matters as much: a backlog that only grows becomes a graveyard of stale intentions that obscures the work that matters.
Why it matters
The backlog is where strategy meets capacity. A well-ordered backlog means the team's next unit of effort always goes to the most valuable known work, and it gives stakeholders one honest place to see what is coming and what is not. It also absorbs pressure constructively: new requests are placed relative to existing priorities in the open, rather than jumping the queue through side channels.
A product example
A product owner reviews the backlog fortnightly: the top ten items are refined stories with acceptance criteria, a scoring pass has just moved a low-effort compliance fix above a glamorous but expensive dashboard, and thirty items untouched for six months are archived after a quick scan. When a sales lead asks for a bespoke report format, it is added, scored and placed — visibly — below the quarter's committed work.
