Timeboxes group related stories and bugs into a defined period with start and end dates. They help teams prioritize work, align around delivery windows, and understand what's planned when. Timeboxes appear on timelines and reflect the current state of the work they include.

Manage timeboxes

The Manage timeboxes page provides a table of all timeboxes in your workspace, with the following details:

Timebox name and description.
Number of timelines the timebox appears on. Hover over the timeline icon to view a list of timelines where the timebox is included.
Number of stories and bugs included. Hover over the story or bug icon to view a list of the items and their current workflow step.
Owner (creator) and last updated date.

From this page you can:

Create new timeboxes.
Edit or delete existing timeboxes.
Search timeboxes by name or description.
Drill into to individual timeboxes to view more detailed information.

View a timebox

You can view a timebox from the Manage timeboxes page, directly from a timeline, or from a story or bug assigned to the timebox:

On the Manage timeboxes page, click the name of the timebox.
On the timeline, double-click the timebox.
When viewing a story or bug, hover over the name of the timebox in the details side panel, and click the arrow icon when it appears.

The timebox details page allows you to:

View and edit the timebox's start and end dates.
Add or remove items.
Review delivery signals for individual items.
View which timelines the timebox appears on.

View items in a timebox

The timebox details page includes a list of all of the items in the timebox, including their item ID, title, workflow step, projected completion, and team backlog. When a timebox includes private team stories and bugs that you don't have access to, their titles will be redacted.

If all items in a timebox belong to the same team, the page also displays the total story points for those items. This total updates automatically as stories are added, removed, or resized.

To view more details about the items, click View items above the item list.

This opens a filtered view of the Everything page, showing only the items in the timebox you have permission to view.

Identify items with warnings

Timeboxes show warnings at the item level so you can see exactly what may affect delivery.

When a story or bug is unlikely to be completed within the timebox dates, it’s highlighted in the timebox details view. These item-level warnings explain why a timeline may show a warning indicator for the timebox.

Warnings don’t prevent items from being included in a timebox. They provide context to help you decide whether to adjust scope, sequencing, or ownership.

Why items show warnings

Warnings appear for a few common reasons:

Projected to finish after the timebox

The Projected completion column shows when an item is expected to be completed.

For items on Kanban teams:

Items in 'To do' or 'In progress' display a projected completion date.
For items already in progress, the projection is based on when the item entered an 'In progress' workflow step and the team’s average cycle time.
If the projected date falls after the timebox end date, the item shows a warning.

Not scheduled (Scrum teams)

For items on Scrum teams, warnings are based on sprint alignment:

The item isn’t assigned to a sprint ('Unscheduled').
The assigned sprint ends after the timebox end date.

In these cases, the Projected completion column reflects the sprint timing rather than a calculated date.

No team assigned

Items that aren’t assigned to a team backlog show a 'No team' warning. Without a team, Atono can’t determine how the item fits into delivery planning.

No projection available

In some cases, Atono can’t calculate a projected completion date. When this happens, the reason is shown instead, such as:

The item is already Done.
The item is in a Won’t do workflow step.
The item is marked as an Outlier.
There's insufficient historical data to calculate a projection.

Limited visibility

If a timebox includes items from private team backlogs that you don’t have access to:

Item titles are hidden.
Projected completion information is shown as 'Private'.

These items may still contribute to warnings, even if their details aren’t visible.

Take actions on warnings

Warnings in the timebox details view are clickable.

Click No team to assign the item to a team directly from the timebox details view.
Click Unscheduled or a sprint/date warning to open the assigned team’s backlog and review the item there.

This lets you quickly investigate delivery risks and take action where available.

Add or remove items from a timebox

To add items, search or select items from the Stories and bugs included in this timebox field.

If an item is already included in another timebox, the name of the timebox will appear next to the the item title. Adding it to a new timebox will prompt a confirmation warning, as the item will be removed from its previous timebox once confirmed.

To remove items, click the X at the far right of the item in the list.

You can also bulk add items from the Everything page. For steps, see Add items to a timebox.

How timeboxes and timelines work together

Timelines surface warnings at a high level so you can identify timeboxes that may need attention. Opening a timebox shows which specific stories or bugs are driving those warnings and why.
