Root Cause Analysis (RCA)

Every failure has a story. Uncover it, prove it, and act on it.

Built for reliability, integrity and process safety teams, AccurAPM RCA brings the most trusted root cause methodologies — 5 Whys and Fishbone, Fault Tree Analysis, and guided structured investigation — into a single guided workspace, connected directly to your asset, inspection and RBI data. AI generates the fault tree and the recommendations, so no investigation begins at a blank canvas — and every hypothesis stays open until your team verifies it.

The Logic Tree builder after Generate with AI: a failure mode for an H2S release branches into four hypotheses and on to physical, human and systemic root causes, with Generate Recommendations beside it.

Capabilities

Key capabilities

✓Guided case creation, with the methodology recommended from the severity of the event.

✓Fishbone, Fault Tree and sequence-of-events builders on one shared canvas — editable solo or live with the investigation team.

✓AI-generated fault trees and recommendations, with logic validation as you build.

✓Launch an RCA straight from an asset, an inspection report or a failure event, pulling the relevant history in automatically.

✓Similar-case retrieval — learn from past investigations across the organisation instead of repeating them.

✓Root cause to corrective action tracking, with due dates, owners and a closure workflow.

✓One-click reporting, plus organisation-wide analytics on recurring root causes.

✓Scales from a field engineer's quick 5 Whys to an audit-ready major incident investigation.

Methodologies

The methods, and when to use each

The right method depends on the failure. They live in the same workspace, so the choice does not dictate which tool you have to open.

5 Whys & Fishbone

Drag-and-drop cause-and-effect diagrams. A field engineer can complete a straightforward 5 Whys in guided mode with no training.

Fault Tree Analysis

Proper AND/OR logic gates, for when the failure path genuinely branches and the logic has to hold up.

Guided structured investigation

Structured sequence-of-events timelines, with the rigour a process safety investigator needs for a defensible major incident report.

The Fishbone and 5 Whys builder after Generate with AI: causes for a leak on an insulated process line set out under Man, Machine, Method, Material, Measurement and Environment, with the 5 Whys chain for the selected cause beside the diagram. — 5 Whys and Fishbone — AI fills the six cause categories, with a 5 Whys chain behind each cause.

The Fault Tree builder, decomposing a failure event into five candidate failure modes, each passing through a logic gate to its own hypothesis node. — Fault Tree — AND/OR gates from the failure event down to each hypothesis.

AI in RCA

What the AI does — and where it stops

Describe the failure and the AI lays out the investigation. It does not reach a conclusion for you.

✓Generates the fault tree — failure modes, hypotheses and candidate physical, human and systemic root causes — so nobody begins at a blank canvas.
✓Generates recommendations for the team to review, and turns the root causes you accept into corrective actions.
✓Flags weak logic before it becomes a wrong conclusion.
✓Every hypothesis stays a hypothesis until a named assignee verifies it as valid or not valid. The investigator is always in control, and the conclusion is always a human one.

Outcomes

Business value

✓Faster investigations — AI removes the blank-page problem and the manual diagram work.
✓More defensible conclusions — structured logic, validated as you build it, and a record an auditor can follow.
✓Corrective actions that actually close — owners, due dates and a closure workflow, rather than a recommendation in a report nobody revisits.
✓No more investigations in someone's inbox — an RCA starts from the asset record and stays with it.
✓Organisational learning — similar-case retrieval and analytics on recurring root causes turn RCA from a compliance task into a driver of reliability.

How it connects

Connected workflow

An investigation is only as good as the evidence behind it. RCA opens with the asset, inspection and risk context already attached.

From Symptom to Root Cause, Faster

Bring us a failure you have already investigated, and we will run it through AccurAPM RCA so you can compare the result with how it actually went.
