Root Cause Analysis Excellence (RCAE) Training by Tonex
Root cause analysis is valuable only when its conclusions are supported by evidence and its corrective actions address the conditions that allowed an event to occur. Root Cause Analysis Excellence (RCAE) Training by Tonex develops systematic investigation practices for equipment failures, quality escapes, process disruptions, and recurring operational incidents. Participants examine event definition, causal timelines, interviewing techniques, barrier performance, and uncertainty management. The course avoids premature conclusions and unsupported personal blame. Cybersecurity can influence incident evidence when logs are altered, monitoring access is compromised, or unauthorized configuration changes affect operations. Investigators must therefore protect cybersecurity-related records and evaluate data provenance. Practical exercises, real-world case studies, and examples of investigation processes and documentation used in root cause analysis projects reinforce each stage.
Learning Objectives
Upon completing this course, participants will be able to:
- Define an investigation charter that establishes the event, scope, impact, and evidence needs.
- Construct defensible event chronologies using corroborated operational records and interviews.
- Apply causal mapping, barrier analysis, and structured questioning without unsupported assumptions.
- Differentiate root causes, contributing factors, triggers, and latent organizational conditions.
- Select corrective actions that address verified causal pathways and measurable risk reduction.
- Assess cybersecurity implications for evidence integrity, digital logs, and configuration provenance.
- Verify corrective action effectiveness and communicate findings in clear investigation reports.

Course Modules
Module 1: Investigation Scope and Evidence Discipline
- Define the event boundary, consequences, and immediate containment decisions.
- Establish investigation authority, independence, confidentiality, and stakeholder roles.
- Identify physical records, operator observations, and digital evidence sources.
- Create evidence registers with custody, timestamps, and source limitations.
- Separate confirmed observations from assumptions and preliminary interpretations.
- Document investigation questions and realistic evidence collection priorities.
Module 2: Event Reconstruction and Causal Reasoning
- Reconstruct event sequences from maintenance histories and operational timelines.
- Resolve conflicting accounts through corroboration and explicit confidence statements.
- Identify failed safeguards and missing detection opportunities.
- Distinguish triggering events from persistent enabling conditions.
- Assess how human, process, design, and environmental factors interact.
- Produce an evidence-linked event map suitable for independent review.
Module 3: Structured Root Cause Analysis Methods
- Apply five whys questioning while testing each causal connection.
- Develop cause and effect diagrams without treating categories as conclusions.
- Use fault trees to explore alternative pathways to the event.
- Assess protective barriers and escalation controls for actual performance.
- Compare competing causal hypotheses against available factual evidence.
- Select methods appropriate to event complexity and data quality.
Module 4: Human Factors and System Conditions
- Evaluate workload, procedures, handovers, and interface clarity objectively.
- Identify latent design weaknesses and organizational control gaps.
- Distinguish procedural deviations from poorly designed working conditions.
- Examine supervision, training adequacy, and competency assurance records.
- Consider contractor and supplier interfaces in shared responsibility failures.
- Write findings that describe system conditions without unsupported personal blame.
Module 5: Corrective Actions and Effectiveness Verification
- Rank candidate actions by causal coverage and implementation feasibility.
- Prefer durable design and control improvements over reminders alone.
- Assign action owners, resources, completion criteria, and due dates.
- Define leading indicators and checks for unintended consequences.
- Confirm implementation using objective evidence rather than closure statements.
- Evaluate recurrence, residual risk, and the need for further investigation.
Module 6: Investigation Reporting and Organizational Learning
- Draft concise findings separating facts, analysis, and recommendations.
- Evaluate integrity of cybersecurity event logs and configuration records.
- Prepare management briefings with evidence gaps and confidence levels.
- Maintain corrective action registers and decision traceability.
- Share validated lessons with engineering and operational governance teams.
- Review repeat incidents to verify that corrective actions remain effective.
