Forecast your product backlog

Teams use the forecast tool to help in their sprint planning efforts. By plugging in a value for the team velocity, the forecast tool will show which items in the backlog can be completed within future sprints. Both tools are team-specific tools that rely on the team's ability to estimate backlog items. Once your team has completed a sprint or two, they can use the team velocity to forecast how much of the backlog they can finish within the upcoming sprints.

Use this article to learn:

  • How to forecast upcoming sprints
  • Required and recommended team activities to support forecasting

Note

To understand the differences between backlogs, boards, and taskboards, see Backlogs, and boards. If your backlog or board doesn't show the work items that you expect or want, see Set up your backlogs and boards.

Prerequisites

  • Connect to a project. If you don't have a project yet, create one.
  • You must be added to a project as a member of the Contributors security group. If you're not on a project or team, get added now.
  • You must be granted Basic access or higher to add or modify work items. For details, see About access levels.

Here's what you need to have in place before you attempt to forecast your team's backlog.

Required:

Recommended:

  • Define and size backlog items to minimize variability.
  • Determine how your team wants to treat bugs. If your team chooses to treat bugs like requirements, bugs will show up on the backlog and be counted within the Velocity chart and forecasting.
  • Set your team's area path. The forecast tool will forecast those items based on your team's default settings. These settings can specify to include items in area paths under the team's default or exclude them.
  • Don't create a hierarchy of backlog items and bugs. The display of the leaf node, the last node in a same-category hierarchy, may only appear on Kanban boards, sprint backlogs, and taskboards. To learn more, see Fix reordering and nesting issues, How backlogs and boards display hierarchical (nested) items.
    Instead of nesting requirements, bugs, and tasks, maintain a flat list—only creating parent-child links one level deep between different-category items. Use Features to group requirements or user stories. You can quickly map stories to features. The map creates parent-child links in the background.
  • At the end of the sprint, update the status of those backlog items that the team has fully completed. Incomplete items should be moved back to the product backlog and considered in a future sprint planning meeting.

Note

If you work with several teams, and each team wants to work with their own backlog, velocity chart, and forecast tool, you can create additional teams. Each team then gets access to their own set of Agile tools. Each Agile tool filters work items to only include those whose assigned area paths and iteration paths meet those set for the team.

Forecast upcoming sprints

Use the forecast tool to get an idea of how many items you can complete within a sprint. By plugging in a velocity, you can see which items are within scope for the set of sprints the team has activated.

To forecast your product backlog, complete the following actions.

To forecast your product backlog, complete the following actions.

  1. From your web browser, open your team's product backlog. (1) Select the team from the project/team selector, choose (2) Work, (3) Backlogs, and then (4) the product backlog, which is Backlog items (for Scrum), Stories (for Agile), or Requirements (for CMMI).

    Open the Boards>Backlogs page

    You can only forecast the product backlog of Stories, Backlog items, or Requirements.

    To choose another team, open the project/team selector and select a different team or choose the Browse option.

    If you work with several teams, and each team wants to work with their own backlog, velocity chart, and forecast tool, you can create additional teams. Each team then gets access to their own set of Agile tools. Each Agile tool filters work items to only include those whose assigned area paths and iteration paths meet those set for the team.

  2. (Optional) To choose which columns should display and in what order, choose Column options. You may want to add the Iteration Path to the set of columns that appear on your backlog. To learn more, see Change column options.

  3. Set Forecast to On and enter your team's predicted velocity. If the Forecasting bar doesn't appear, set Parents to Hide.

  4. Set In progress items to Hide to hide those items that won't be counted in the forecast. The forecast tool ignores Scrum items set to Committed or Done and Agile and CMMI items set to Active, Resolved, or Completed.

    The tool draws lines for each future sprint selected by the team. The Forecast lines show how much work your team can complete in future sprints. Typically, items above the first line are already in progress for the current sprint. Items that fall between the first and second forecast lines indicate what can be completed in the named sprint.

Review the forecast results

  • Check the results manually to understand discrepancies in what you expect and what the forecast tool displays.
  • Check the amount of effort (Effort, Story Points, or Size) forecasted per sprint.
  • Question forecast results where the effort of an item is near to, or greater than, team velocity.

The forecast tool shows only those work items that can be completed within a sprint between the forecast lines. Unused velocity points from one sprint are considered in the forecast of the following sprint. The forecasted sprint is listed along with the last item that can be completed during that sprint.

In this example, a velocity of 20 is used. The first two items with a total of 13 Effort points can be completed in Sprint 2.

In summary:

  • Sprint 2: 13 Effort points, items 1 and 2 can be completed; 7 velocity points are carried over to the next sprint
  • Sprint 3: 24 Effort points, items 3 through 5 can be completed; 3 (=20+7-24) velocity points are carried over to the next sprint
  • Sprint 4: 21 Effort points, items 6 through 8 can be completed; 2 (=20+3-21) velocity points are carried over to the next sprint
  • Sprint 5: 16 Effort points, items 9 through 12 can be completed; 6 (=20+2-16) velocity points are carried over to the next sprint
  • Sprint 6: 19 Effort points, items 13 through 15 can be completed; 3 (=20+6-23) velocity points are carried over to the next sprint

Determine the velocity needed to complete all items in the backlog

Another way to use the forecast tool is to enter different velocity values until all the backlog items are completed within a given set of sprints. This forecast provides an estimate of what velocity is required to complete your backlog of items.

You can then assess the delta between the current team's velocity and the required velocity. The delta helps determine what other resources are required to meet production demands within a required time.
