Fault tree
How basic faults combine, through AND/OR gates, into the failure.
An OR gate fires if any input does; an AND gate needs all of them. Fault trees expose the combinations where two tolerable faults become one catastrophe.
What this method tells you
Fault tree is one of the analytical methods Niobia AI surfaces inside the rca & 8d branch. The short readout is: An OR gate fires if any input does; an AND gate needs all of them. Fault trees expose the combinations where two tolerable faults become one catastrophe.
Where it fits in Niobia
Niobia keeps this method connected to the surrounding workflow, so teams can move from cause analysis into adjacent methods without reformatting data or rebuilding the context from scratch.
Method-specific output, not just a screenshot
Niobia packages fault tree alongside the rest of the rca & 8d stack, so the result stays connected to the raw inputs, the upstream context, and the next method the team needs to run.
Frequently asked
What does Fault tree help a team understand?
Fault tree sits inside Niobia AI's rca & 8d workflows and helps teams turn raw process, materials, or quality signals into a defensible engineering readout.
When should engineers use Fault tree?
Use Fault tree when the question is better answered by that specific method than by a generic summary: it provides the method-specific signal, tradeoffs, and context the broader workflow depends on.
What should I read alongside Fault tree?
The closest companion methods are Fishbone (6M), 5 Whys, Pareto. Reading them together makes it easier to see how Niobia AI moves from one analytical method to the next.
