Incident Timeline

High-noise incidents generate hundreds of Slack messages, status updates, and decisions. Without structure, the timeline becomes a wall of text that nobody reads during the postmortem. Tellagen gives incident commanders a structured timeline with workstream lanes, tags, and clear ownership — so the record is useful while the incident is still active, not just afterward.

Workstream lanes keep parallel efforts visible

Real incidents have multiple workstreams running simultaneously: detection, mitigation, communication, and customer impact. Tellagen lets you organize timeline events into named lanes so commanders can scan by stream rather than scrolling through chronological noise. Each lane shows who owns it and what the latest status is.

Tags and filters for fast triage

Every timeline event can carry tags — severity changes, key decisions, customer-facing updates, rollback actions. During a live incident, commanders filter by tag to isolate what matters. During post-incident review, the same tags power structured exports that skip the noise and surface the decisions.

Ownership at the event level

Each timeline entry is tied to a specific responder. This is not about blame — it is about knowing who made a decision and who to ask for context during the review. When handovers happen mid-incident, ownership transfers create a clear record of who was responsible at each phase.

Audit-ready export for postmortems

When the incident closes, export the full timeline as a structured document. Workstream groupings, timestamps, ownership, and tags are preserved. The export is designed for post-incident review meetings — not as a raw log dump, but as a readable narrative of what happened and why.

Frequently asked questions

Can I customize workstream lane names?

Yes. Workstream lanes are fully configurable per team. You can create lanes that match your incident response process — detection, mitigation, customer comms, or whatever your team uses.

How does the timeline integrate with Slack?

Tellagen listens to your incident Slack channels and suggests timeline events based on high-signal messages. Responders review and approve suggestions before they are added to the timeline.

Can I export the timeline for compliance purposes?

Yes. Timeline exports preserve full structure including timestamps, workstreams, ownership, and tags. Exports are suitable for compliance reviews, post-incident meetings, and archival.
