Product Backlog


The product backlog is an ordered list of everything that might be needed in the product and is the single source of requirements for any changes to be made to the product. The product owner is responsible for the product backlog, including its content, availability, and ordering.

A product backlog is never complete. The earliest development of it only lays out the initially known and best-understood requirements. The product backlog evolves as the product and the environment in which it will be used evolves. The product backlog is dynamic; it constantly changes to identify what the product needs to be appropriate, competitive, and useful. As long as a product exists, its broduct backlog also exists.

The product backlog lists all features, functions, requirements, enhancements, and fixes that constitute the changes to be made to the product in future releases. Product backlog items have the attributes of a description, order, estimate and value.
