Backlog

In simple English

The backlog is the main repository of all requested work for a project. It's managed by the Product Owner and constantly updated as priorities change, new features are requested, or bugs are discovered. Items move from the backlog into sprints or active development cycles.

Wondering what 'backlog' means in Agile or Scrum? Here's the complete guide for tech teams.

Real examples

Standup

"We've been working through the backlog pretty fast this sprint—we might take on extra items if we finish early."

Slack

"That bug report came in, so I added it to the backlog for next sprint's planning session."

Jira ticket

"Status: Backlog. This feature request will be evaluated during backlog refinement next week."

Sprint Planning

"The backlog is huge right now—we need to prioritize which stories to pull in for this sprint."

Retrospective

"I think we're pulling in too much from the backlog each sprint. We should be more realistic about capacity."

Code review

"This is addressing the technical debt item that's been in the backlog for three months."

Interview

"In my last role, I helped manage a product backlog of about 200 items and prioritized them based on customer feedback."

Don't say this

We need to complete the entire backlog this quarter.
We need to prioritize and address the top backlog items this quarter.The backlog is never completely 'completed'—new items are always added. You work through prioritized items, not finish everything.
The backlog is our to-do list for today.
The backlog is our list of work for the upcoming sprints or development cycles.The backlog is medium- to long-term work, not daily tasks. Daily tasks come from the current sprint or board.
We backlogged the feature until next month.
We added the feature to the backlog for consideration in a future sprint.'Backlog' is a noun, not typically used as a verb in this way. Say 'added to the backlog' or 'deferred' instead.
