The Product Owner is responsible for composing the Product Backlog items.

There’s only one Product Owner for one project; full-time or part-time. The person should be business-oriented. A qualified business analyst is a very good candidate for this role.

The Product Owner is constantly in contact with the customer, understands their requirements, and turns them into Product Backlog items. Then the Product Owner assigns a “business value” to each item, and sorts the Product Backlog. So, more important items will be on the top of the list. Those items on the top are what we will be doing in the next iteration.

So, we spend only a few days creating enough items in the Product Backlog, and then we will start the first iteration.
Iterations are called Sprints in Scrum. Let’s talk about them in the next lesson.
