In project management, the term "backlog" refers to a prioritized list of tasks, requirements, features or work items that need to be accomplished to achieve a project's objectives. It is commonly used in agile methodologies such as Scrum or Kanban. Here's a more detailed description:
- Product backlog: In Scrum, the product backlog is a prioritized list of everything needed for the product. It is maintained by the Product Owner and contains features, enhancements, bug fixes, technical requirements, and any other tasks needed to develop the product. Product backlog items are often in the form of "User Stories" or technical tasks.
- Sprint backlog : Also in Scrum, the sprint backlog is a list of tasks to be completed during a particular sprint. It is derived from the product backlog, but focuses solely on what needs to be done in the current sprint. The development team selects items from the product backlog and moves them into the sprint backlog based on their ability to accomplish these tasks within the sprint duration.
- Kanban Backlog: In the Kanban methodology, the backlog represents work items that need to be completed but have not yet been started. These items are often placed in a column entitled "Backlog" on the Kanban board. Unlike Scrum, there are no defined sprints; work is simply drawn from the backlog as resources become available.
Backlogs are dynamic, evolving tools, updated regularly to reflect changing priorities and new information. They help organize work, manage priorities and ensure that the team is focused on the most important tasks at all times.
