The guardrail band beside a track's Sankey ribbons shows how much of that team's capacity is committed, unallocated, unavailable, or spent on ad hoc work.
What it is
Next to the Sankey ribbons for a given track (a team or workstream at a hierarchy level), Everview renders a guardrail band summarizing that track's capacity for the current period, broken into four figures:
- Net capacity — the track's total available points.
- Unallocated — capacity not yet assigned to any project.
- Unavailable — capacity lost to time off or other absences.
- Ad hoc load — points going to unplanned work rather than committed projects.
How to read it
Each figure is shown as both a point value and a percentage of net capacity, so you can compare tracks of different sizes at a glance. A track with a large unallocated figure has room to take on more committed work; a large ad hoc figure means a meaningful share of that team's capacity is already going to work outside the roadmap.
What to do about it
If a track's ribbons look under-loaded but its guardrail shows high ad hoc load, the team may already be at capacity — the roadmap view alone would understate that. Check ad hoc load before assigning new committed work to a track, and treat a persistently high unallocated figure as a planning gap worth filling rather than banked slack. Pair this with Understanding the Execution Hierarchy to see which projects sit on this track, and with Capacity and Availability for how a single sprint's capacity is calculated.
