DevOps Professional · Module 7: Incident leadership and handover
Incident Coordination: One Lead, One Timeline, One Order
Incidents need a conductor more than another debugger. One lead holds the timeline and the order, tasks fan out, communication flows on schedule, and the lead can change hands without dropping the response.

Objectives
- Explain the lead's job: coordinate, communicate, decide, never debug alone
- Build a timeline from changing event cards in response order
- Assign response order: mitigate users first, evidence always, diagnosis second
- Hand off the lead cleanly mid-incident without losing the thread
Why this matters
Six engineers join an incident bridge and all six debug different theories. Nothing is communicated, two fixes collide, and the timeline is rebuilt from memory days later with gaps. The missing role was not expertise but coordination: someone holding the whole picture while others work pieces. The L67 lab builds a timeline plus response order from changing event cards; this lesson explains why the order matters more than any single fix.
Concepts
The lead coordinates: declares severity from user impact, assigns tasks with names and times, runs the clock on updates, and decides when the response changes direction. The lead does not debug a theory personally; a debugging lead abandons coordination, and the bridge dissolves into parallel solo work. Small incidents need a light lead (one person narrating decisions); large ones need the full rolewith a scribe capturing the timeline live.
Response order never changes: users first (mitigate), evidence always (preserve logs, snapshots, timelines before they rotate), diagnosis second (theories after mitigation), communication throughout (users, stakeholders, next responders). New event cards reorder tasks, never the order itself: a worse symptom escalates mitigation, a new clue redirects diagnosis, but diagnosis never jumps ahead of mitigation while users hurt.
Handover mid-incident is a designed motion. Outgoing lead briefs: current impact, actions in flight with owners, open questions, next update due. Incoming lead repeats back and assumes the clock. The L69 handover package (lesson 3) makes this possible across shifts; without it, handover is folklore and the new lead restarts discovery while the incident continues.
Worked example
A fixture incident deals changing event cards: impact report, partial mitigation, conflicting theory, new symptom. The learner orders the response card by card: mitigate first, preserve the rotating log, park the theory until mitigation lands, update stakeholders on the clock. A mid-drill handover brief transfers the thread with nothing lost; the timeline quotes every decision with its trigger card.
Common wrong move
Everyone debugging, nobody leading. Parallel theories feel productive and produce collisions, gaps and silence. First motion of any incident: name the lead, start the timeline, then work.
Quick check
An optional 4-question self-check. Answers never leave your device, are not stored, and never count toward any assessment.

Exercise
On changing fixture event cards, build the timeline in response order with a mid-drill lead handover, and quote each decision with its trigger.
Pass criteria
The record shows the ordered timeline, the handover brief with read-back, and every decision linked to its triggering card.
