Root Cause Analysis

Professional Incident Investigation & Root Cause Analysis

Find the real cause. Prevent the next incident. Expert investigation using ICAM, RCA, Bow Tie, and SCAT methodologies — from rapid response deployment to corrective action closure.

Investigation Methodologies

Every investigation is conducted with rigour and impartiality, using industry-recognised frameworks that uncover systemic causes — not just immediate triggers.

ICAM Analysis

Incident Cause Analysis Method — a structured, human-factors-based approach that identifies absent/failed defenses, individual and team actions, and organizational factors.

Bow Tie Analysis

Visual risk model linking threats through top events to consequences. Identifies prevention barriers (left side) and mitigation controls (right side) — ideal for major hazard incidents.

Root Cause Analysis (RCA)

Systematic investigation through why-why, fishbone, fault tree, and 5-Whys techniques to identify underlying root causes and contributing factors.

SCAT Method

Systematic Cause Analysis Technique using the ILCI Loss Causation Model. Maps immediate causes to basic causes to substandard acts and conditions.
