What is the Product Backlog and how should it be maintained?

Short answer: Follow On: Definition: The Product Backlog is an ordered list of everything that might be needed in the product, serving as the single source of work for the Scrum Team.

Explain a bit more

How to maintain it: Continuously refine items for clarity, detail, and priority. Regularly update it based on feedback, market changes, and stakeholder input. Collaborate with the team to ensure shared understanding. Real-World Example: For a streaming platform, the backlog might start with high-level features like “Watchlist” and “User Reviews”. As sprints progress, these are broken down into more detailed items like “Add to Watchlist Button” or “Review Moderation Rules”.
