Does this skill provide solutions for the identified problems?

No, the core philosophy of this RCA skill is that analysis is about evidence gathering and prevention gaps (the 'what'), not prescriptive solution design (the 'how').

Can I use this for non-technical incidents?

Yes, while designed for software systems, the structured methodology of causal chains and isolation tests can be applied to process and organizational failures.

What is differential analysis in this context?

Differential analysis is a required step that examines why a specific case failed while similar cases succeeded, highlighting unique conditions or safeguard failures.

What are the Three Tests for root cause isolation?

The skill uses the Counterfactual, Sufficiency, and Necessity tests to ensure a factor is the true root cause rather than just a contributing or amplifying factor.

Analytics & Monitoring

Conducts structured root cause analysis using an evidence-based methodology to isolate true system failures from contributing factors.

The RCA Analyst skill provides a rigorous, five-phase framework for conducting deep-dive investigations into system failures and incidents. By applying the specialized 'Three Tests'—Counterfactual, Sufficiency, and Necessity—the skill helps developers and SREs move beyond symptoms to identify the singular root cause that, if removed, would prevent the failure. It guides users through evidence gathering, causal chain construction, and differential analysis, resulting in a professional RCA document that focuses on systemic prevention rather than just immediate fixes.
