How long does the product backlog exists?
A product backlog is a list of all the features that need to be added to a product to make it complete. It's usually ordered by priority and contains everything from bugs to new features.
The product backlog is created by the team working on a project, who use it as a way of keeping track of what needs to be done and when. A good product backlog should be easily understood by everyone involved in the project, so that they can see what's coming up next and make decisions about how they can best use their time.
Our product backlog exists as long as it needs to.
When a team member is working on a task, they will be able to see their progress towards completion. The product backlog is always available for the team to refer back to if they have questions about what needs to be done or are struggling with a particular task.
The product backlog is a living document that is continuously updated as new features are added and old ones are removed. The product backlog exists until the product is completed and ready to be released to customers.
