What problem does it solve?

This Skill helps you perform consistent, organizationally focused post-incident reviews by turning incident facts into a structured timeline, impact assessment, root cause analysis, and corrective action plan—without drifting into log-level technical debugging.

Core Features & Use Cases

• Incident information gathering: Collects interview-based facts (what happened, when, who was involved) and identifies missing information gaps.
• Timeline & metrics: Constructs a chronological timeline and computes key metrics (TTD, TTR, TTM, TTRe) plus bottleneck identification.
• Impact assessment (P0–P4): Evaluates impact across user, service, business, and operational dimensions using an SLA/severity matrix and quantifies business impact.
• Root cause analysis (RCA): Provides process/system-oriented RCA via 5 Whys with branching, Fishbone (People/Process/Technology/Environment/Data/External), and Fault Tree Analysis with SPOF-focused insight.
• Corrective actions that actually execute: Produces SMART corrective actions using the 3D Prevention Framework (Detect/Defend/Degrade) and organizes them into time horizons (immediate/short-term/long-term) with ownership tracking templates.
• Full RCA report generation: Outputs a comprehensive Markdown RCA report using Japanese or English templates.
• Blame-free guidance: Enforces a method of focusing on process and system improvements, including decomposing “human error” into process/system/training gaps.

Quick Start

Use the incident-rca-specialist skill for a completed (mitigated or closed) incident where you need to produce an incident timeline, severity assessment, root cause analysis, and a SMART corrective action plan (without performing log-level debugging).
