Overview:
This artifact contains a list of all scheduled work to be done within the project, as well as proposed work that may affect the product in this or future projects. Each work item may contain references to information relevant to carry out the work described within the work item.

Purpose:
To collect all requests for work that will potentially be taken on within the project, so work can be prioritized, effortestimated and progress tracked.

Main Description:
This artifact provides a focal point for the entire team:

• It provides one list containing all requests for additional capabilities or enhancement for that application. Note that some of these requests may never be implemented, or be implemented in later projects
• It provides one list of all the work to be prioritized, estimated, and assigned within the project. The risk list is prioritized separately.
• It provides one place to go to for the development team to understand what Micro-Increments need to be delivered, get references to material required to carry out the work, and one place to go to report progress made.

These are the typical work items that go into this list:

• Use cases (and references to use-case specifications)
• Supporting requirements
• Changes and enhancement requests
• Defects
• Development tasks

Work items can be very large in scope, especially when capturing requests for enhancements, such as Support Financial Planning for a personal finance application. To allow the application to be developed in micro-increments, work items are analyzed and broken down into smaller work items so they can be assigned to an iteration, such as a use-case scenario for Calculate Net Worth. Further breakdown may be required to identify suitable tasks to be assigned to developers, such as Develop UI for Calculate Net Worth. This means that work items often have parent/child relationships, where the lowest level is a specification and tracking device for micro-increments.
