How Event Tree Analysis (ETA) Works in SolveRight

When you run a decision through SolveRight, Event Tree Analysis (ETA) is one of up to 155 frameworks that analyze your options simultaneously. The AI extractor identifies 4 key data points from your decision description, then the probabilistic rubric computes a normalized 0-100 score for each option. This score is combined with results from other frameworks to produce your overall ranking, with contradiction detection highlighting where Event Tree Analysis (ETA)disagrees with other methodologies.

Event Tree Analysis (ETA) — Frequently Asked Questions

What is Event Tree Analysis (ETA)?+
Models possible outcomes following an initiating event through sequential barrier successes and failures. In SolveRight, Event Tree Analysis (ETA) uses a probabilistic rubric to compute a normalized 0–100 score for each option.
When should I use Event Tree Analysis (ETA)?+
Event Tree Analysis (ETA) is best suited for Risk Assessment decisions. It evaluates factors like initiating event, barrier list, success failure probability, making it valuable when you need identifying, quantifying, and mitigating potential downsides.
How does SolveRight use Event Tree Analysis (ETA)?+
SolveRight runs Event Tree Analysis (ETA) alongside up to 154 other frameworks simultaneously. The AI extractor identifies 4 key data points from your decision description, then the probabilistic rubric computes deterministic scores. If Event Tree Analysis (ETA) disagrees with other frameworks, contradiction detection highlights the divergence.
