Capacity preflight

The Resource Manager’s view of an active sprint, at-a-glance. A donut chart shows aggregate committed/capacity ratio; a scrollable list shows per-person commitments with avatar initials. Three colour bands signal severity: under, at, or over capacity.

Where this lives in the story

Step 3 (Capacity preflight) of the hybrid PM flow — Sarah’s veto surface. Catches contention at plan time before sprint execution starts.

What you see

• Donut chart — aggregate ratio (committed_hours / available_hours), tinted by band:
  • under 90% → semantic-on-track
  • 90–100% → semantic-at-risk
  • over 100% → semantic-critical
• Aggregate label — {committed} / {capacity} hours committed · On track · {buffer} hours of buffer (or overrun when negative)
• Per-person rows — initials avatar + name + {committed}/{capacity} text; over-allocated members get a red avatar tint

Where to find it in the app

• Route: /projects/:projectId/sprints (right column of the metrics row, top half)

API endpoints

Method	Endpoint	Purpose
GET	/api/v1/sprints/{id}/capacity/	Per-member committed/available hours + aggregate totals

The activate endpoint also surfaces a warnings-only slice via capacity_check; this endpoint exposes the broader dataset.

Where the data comes from

For each TaskResource assigned to a task in the sprint:

committed_hours = sum(units × working_days × hours_per_day)
available_hours = max_units × working_days × hours_per_day

Working days span the sprint window honouring the project calendar’s working_days bitmask. Hours-per-day is read from the calendar (8.0 default).

PTO is a placeholder zero until a dedicated time-off model lands.

• ADR-0037 §Q2 — Capacity check at activate time

If you are…

• Sarah (Resource Manager) — this is your veto surface. If the aggregate is over 100% before activate, escalate before the sprint starts.
• Maya (Scrum Master) — the per-person list answers “who’s overcommitted?” without a separate spreadsheet.
• Raj (PM) — capacity warnings on activate inform whether to pull scope before the sprint window opens.
