The Product Backlog in Scrum plays a pivotal role in managing and tracking the course of product development. Essentially, a Product Backlog is a prioritized list of product features, improvements, bug fixes, and other changes that need to be made to the product during the course of its development. In better understanding the evolutionary characteristic of the Product Backlog, we grasp more than just the dynamic nature but also its strategic importance in aligning product development to business goals or user needs.
AN EMERGENT LIST OF REQUIREMENTS
A Product Backlog is emergent, which means it constantly evolves over time. It doesn’t start as a comprehensive list but takes shape and matures over the course of the product life cycle. It evolves based on user feedback, market trends, or business outcomes analyzed during Scrum meetings such as the Sprint Review. This makes the Backlog a living document that is continuously revisited, refined, and reprioritized as per new insights and understanding gained through ongoing work and feedback loops.
For example, consider a team building an e-commerce application. Initially, the Product Backlog may include basics like user registration, catalog display, and cart functionalities. But as they receive feedback from the alpha testing, they might need to include more complex functionalities like personalized recommendations or express checkouts, thereby causing the backlog to evolve.
IMPROVEMENT OF THE PRODUCT
The Product Backlog is decisively targeted at product improvement. It provides an explicit order of what to do next. The Product Owner, who is primarily responsible for the Backlog, continuously works with stakeholders and the Scrum Team to define and refine the items on the Backlog ensuring they align with the project’s goals and expectations.
Let’s continue with the same e-commerce application example. Post the 1st Sprint, the users may indicate that the app’s speed is slow. Now, improving speed becomes a high-priority Product Backlog item. In the coming Sprints, the Development Team picks up this item and works to enhance the app’s speed, thereby improving the product.
PRIORITIZATION OF BACKLOG ITEMS
One of the key activities involved with managing the Product Backlog is the act of prioritization. The Product BacklogItems (PBIs) are arranged based on business value, risk, and necessity, among other factors. It helps the Scrum Team and stakeholders to focus their attention on what needs to be done first to deliver the maximum value.
Again, in our e-commerce app, assume there are two feedbacks – one pointing out the absence of a wishlist functionality and another reporting slow speeds. The Product Owner will have to prioritize which one to go ahead with. If the slow speed is costing the business more losses due to dissatisfied customers, it becomes a higher priority item than the wishlist feature.
FINAL THOUGHTS
The Product Backlog’s emergent nature paired with its orientation towards product improvement makes it an integral part of Scrum. It forces the team to constantly align themselves with business and market needs, thereby ensuring they deliver a product that brings vital value to its users and significant returns for the stakeholders. It’s not just a simple to-do list but serves as a strategic tool for value-driven product development.
Remember that successful management of the Product Backlog demands constant attention, good communication, and efficient prioritization skills to ensure the swift and effective delivery of the product.

Interview Questions
What does it mean that a Product Backlog is an “emergent” list?
An emergent list means that the Product Backlog evolves over time. As more is learned about
the product, its users, and its uses, the Product Backlog items are constantly revised, updated and
prioritized.
How does the Product Backlog improve a product?
The Product Backlog improves the product by providing a list of all the functionalities, adjustments,
and features deemed necessary to meet the product’s goal. It keeps the team focussed and provides a
road map of what needs to be accomplished for its evolution.
Who is responsible for maintaining the Product Backlog?
The Product Owner is responsible for maintaining the Product Backlog. They are responsible for the
contents, availability, and ordering of items in the Product Backlog.
What happens to an item on the Product Backlog after it has been completed?
Once an item from the Product Backlog has been completed and meets the Definition of Done, it is
considered “Done” and is removed from the Product Backlog.
How often is the Product Backlog updated?
The Product Backlog is a living document that constantly evolves and should be updated and refined
regularly, usually before every Sprint Planning.
What are the characteristics of a good Product Backlog?
A good Product Backlog is DEEP: Detailed appropriately, Emergent, Estimated, and Prioritized.
How does the Product Backlog promote visibility and transparency?
The Product Backlog promotes visibility and transparency by serving as a single source of requirements
for changes to be made to the product. Every stakeholder can see what work will be addressed and the
priority of that work.
What is the purpose of prioritization of the Product Backlog?
Prioritization ensures that the most valuable and impactful work is done first. It is a way to manage
risk and provide the most value to users and stakeholders as soon as possible.
When can new items be added to the Product Backlog?
New items can be added to the Product Backlog at any time by the Product Owner.
Why is the Product Backlog considered to be a living artifact?
The Product Backlog is considered a living artifact because it constantly evolves over the life of the
product. As the product and its market circumstances change, the Product Backlog is updated and revised
accordingly.
What factors may lead to changes in the Product Backlog?
Various factors can prompt a change in the Product Backlog. These include market conditions, business
priorities, technology advancements, feedback from stakeholders, or insights from the development team.
How is the impact of changes in the Product Backlog managed in scrum?
Changes in the Product Backlog items are managed by continually refining and re-prioritizing them based
on value, risk, learning and necessity.
Can the Scrum Team suggest changes to the Product Backlog?
Yes, the Scrum Team can suggest changes or improvements to the Product Backlog. Final decision on what to
include in the Product Backlog lies with the Product Owner.
How are Product Backlog items selected for a Sprint?
The Product Owner presents the top priority items on the Product Backlog at the Sprint Planning meeting.
The Scrum Team then determines how many items they can complete during the coming Sprint.
What is the importance of ordering the Product Backlog?
Ordering the Product Backlog helps the team to understand what needs to be done next, provides a clear
sense of direction, and helps to plan for the upcoming Sprints. It makes sure that the most important tasks
are completed first.
