Incident Timeline & RCA Builder
Enter an incident's events as a small timeline and mark the contributing-factor domains you observed; a fixed rule set orders the timeline, derives the milestone spans, and structures candidate contributing factors with the evidence for each. It never names a root cause - candidates to investigate, not a verdict.
Operations & FieldcraftAdd the incident's events and set an order for each (lower runs earlier). The tool has no clock - you control the sequence; spans are counted in events.
Tick the domains you have reason to investigate. Tick "mark confirmed" only for a factor you have confirmed from your own evidence - the tool never confirms one for you.
Optional detail for the export (does not affect the scaffold)
These lines are copied verbatim into the exported scaffold so the review write-up starts complete.
Runs entirely in your browser. The free-text notes flow only into the exported scaffold - they never influence which candidates appear, and nothing is uploaded.
Build the timeline above and the RCA scaffold appears here - the ordered timeline, the milestone spans, and the candidate factors to investigate, live as you refine.
