The product backlog is an order queue where every item (PBI) is everything needed to improve the product, so this is the only source of work.
It’s essential that the product owner creates and explains the object in the product backlog and orders it by importance.
The Developers select the item ready for selection from the product backlog during the sprint planning.
But how does this item become ready for selection?
Backlog Refinement’s ongoing activity, where the less exact item was breaking down into smaller and more specific things. Are the Developers at the Sprint planning that state if one PBI is detailed enough to be ready to work?
Some important point about the product backlog is:


  • One product has one product backlog and one product owner;
  • More team can work on the same product backlog (is the case of the Scrum of Scrum or another scaling framework);
  • The PBI can have a different form, like non-functional requirements, defects, technical debt, etc.
  • From the product backlog, the Developers find the requirements for the implementation. Some people say that the product backlog is the only source of truth;
  • In the product backlog refinement comes Lean Thinking;
  • In order to prevent waste, the refinement is done on the essential item just before they are needed.

The commitment of the product backlog is the Product Goal.
The scrum guide state:

The Product Goal describes the product’s future state, which can serve as a target for the Scrum Team to plan against.
This is a long-term target, and only when the goal is fulfilled (or abandoned) can you have another one.

  • Is the product owner responsible for ordering the product backlog;
  • An item can have different from;
  • The product backlog refinement is an ongoing activity;
  • One product has one product backlog and one product owner (but more different teams can work on it);
  • The product backlog is the only source of truth;
  • The commitment of the product backlog is the Product Goal;
  • The product goal is a long terms target.
  • You can have only one product goal at a time
