Vertical root cause analysis is performed by repeatedly asking why on a single statement to reach its irreducible foundation. It follows a single line of inquiry downward, naming each layer clearly to expose the logical crack leading to the next deeper level.

Deep analysis focuses on vertical depth by following a single line of inquiry downward to fundamental principles, whereas broad surveys branch out horizontally. Use vertical inquiry when breadth is not needed and only the underlying mechanism matters.

You should stop asking why during layered reasoning when further reduction becomes a tautology or hits a fundamental principle. This stopping point means you have reached the irreducible foundation of the phenomenon.

To find a hidden mechanism beneath a surface explanation, apply layer-by-layer breakdown to the observation. By exposing the crack at each level and asking why, you drill down until the underlying mechanism is reached.

Yes, you can use deep analysis for exploring why an event happened by applying vertical inquiry. It isolates a single event and performs conceptual debugging downward instead of branching into broad brainstorming or surveys.

The best way to debug a concept to reach its logical foundation is to repeatedly ask why through layered reasoning. You must concisely name each level until further reduction becomes a tautology or fundamental principle.
