A well-organized product backlog is at the heart of every successful Agile team. It guides priorities, aligns stakeholders, and helps the team stay focused on delivering value. But what exactly goes into a product backlog?

In this post, we’ll explore different types of Product Backlog Items (PBIs), provide real-world examples, and answer common questions Agile teams often have.

‍

What Is a Product Backlog?

The product backlog is a living, prioritized list of all the work needed to build and improve a product. It includes everything from user-facing features to internal improvements and technical work. The Product Owner owns the backlog and is responsible for keeping it up to date and prioritized based on business value and team feedback.

‍

Types of Product Backlog Items (With Examples)

1. User Stories

These represent functionality from a user’s perspective.
Example:
As a user, I want to save favorite items so I can access them later.

‍

2. Technical Tasks

Work that supports development, performance, or infrastructure.
Example:
Optimize database queries for faster load times.

‍

3. Bugs / Defects

Issues that disrupt functionality.
Example:
Fix login issue on Safari browsers.

‍

4. Spikes (Research Tasks)

Exploratory tasks to reduce uncertainty.
Example:
Evaluate third-party API options for email notifications.

‍

5. UX / UI Improvements

Changes that improve usability and experience.
Example:
Update mobile navigation for easier access to settings.

‍

6. Maintenance / Chores

Routine cleanup or non-functional requirements.
Example:
Archive users inactive for more than one year.

Best Practices for Managing PBIs

• Write clear, actionable items with acceptance criteria.
• Break larger features into smaller, testable stories.
• Continuously refine the backlog with the team.
• Use prioritization frameworks like MoSCoW or Value vs. Effort.
• Keep top items sprint-ready.

FAQ: Product Backlog Items

What is the difference between a product backlog and a sprint backlog?

The product backlog is the master list of all desired work, while the sprint backlog is a subset of prioritized items selected for the current sprint.

‍

Who is responsible for managing the product backlog?

The Product Owner owns and maintains the product backlog, ensuring it reflects business priorities and stakeholder input.

‍

Can bugs and technical tasks go in the product backlog?

Yes. A healthy backlog includes bugs, tech debt, and infrastructure work, not just user stories.

‍

How often should the backlog be updated?

The backlog should be reviewed and refined continuously—typically once per sprint during backlog grooming or refinement sessions.

‍

Should every backlog item follow the user story format?

No. While user stories are great for capturing customer value, other items like spikes, bugs, and tasks may use different formats.
