🧾 What Is a Product Backlog?

The Product Backlog is an ordered list of everything that is known to be needed in the product. It evolves continuously as the product and its environment evolve.

It contains:

• Features

• Enhancements

• Bug fixes

• Technical work

• Knowledge acquisition
  
  

The Product Owner is responsible for managing the backlog - prioritizing and ensuring clarity for the team.
