A product backlog shows what needs to be worked on in a product. It usually contains many different items: new features, small improvements and things to refurbish internally. Most product owners use the product backlog to capture anything that arises in their daily work. Customer requests, strategic enhancements, ops improvement and technical refactoring live in the product backlog. In order to focus on the most important topics a ranking of items is desirable. Product owners can choose from various backlog prioritization methods to identify the top items that need to be worked on. Most prioritization techniques balance cost and benefit of each item. While benefit can be measured in various ways, user feedback is a great way to capture benefit. Productific provides feature voting to capture the benefit of backlog items such that owners can decide what to build next.
