What is the Product Backlog? • The Product Backlog is
a single artifact describing everything about a product. • The Product Backlog must be transparent to the entire development team. • It is critical to manage the Product Backlog right to succeed in Agile development. -
What is Product Backlog Items (PBIs) • The PBI represents
a piece of work that needs to be completed in order to build the product. • All development activities are managed based on PBIs. • The Product Backlog is a collection of PBIs. -
Relationship between Roles and Product Backlog • The Product Owner
is responsible for the Product Backlog by clarifying requirements, prioritizing and getting feedback from stakeholders. • While the Product Owner remains responsible, management can be delegated to the developers. • If the Product Owner and Developers are not experienced enough, the Scrum Master coaches them on how to manage it. -
Product Backlog Hierarchy • The theme represents the high-level business
strategy and objectives in the long term. • The epic is a large, valuable PBI that cannot be completed within a sprint and must be divided into several smaller User Stories. • The User Story is a single valuable PBI that is small enough to be completed within a sprint. • Tasks are the breakdown of the user story. -
Details of PBI Layer Description Length Example Theme Top Level
Objective Several months to years Increase website traffic Epic Large value More than a Sprint Make a landing page User Story Core value Within a Sprint Develop a search function Task Specific Tasks Few days Code a back-end program -
INVEST Framework Independent A PBI should be independent from other
PBIs. Negotiable The Product Owner and Developers can negotiate. Valuable PBIs must be valuable for users. Estimable PBIs can be estimated. Small A PBI can be completed within a Sprint. Testable PBIs are testable through Acceptance Criteria. -
