Root Cause Analysis & Engineering Problem-Solving

Root Cause Analysis & Engineering Problem-Solving

Can you distinguish a convincing explanation from a cause supported by evidence?

This assessment uses realistic industrial cases to evaluate your ability to define problems, interpret evidence, test competing explanations, and select corrective actions that address demonstrated causes.

Assessment details

• Questions: 30 single-choice questions.
• Answer options: Four per question, with one best answer.
• Recommended time: 60 minutes.
• Level: Practitioner, with selected advanced investigation scenarios.

Topics covered

• Problem definition and investigation scope.
• Evidence collection and event timelines.
• Causal analysis and appropriate use of RCA tools.
• Hypothesis testing and quantitative data interpretation.
• Corrective actions and risk-based prioritization.
• Effectiveness verification and organizational learning.

Instructions

Read each case carefully and distinguish observations, assumptions, hypotheses, and confirmed findings.

When several explanations remain possible, select the evidence or test that best distinguishes them. Consider technical, operational, and organizational factors before reaching a conclusion.

For quantitative questions, check observation periods, operating exposure, units, and stated assumptions. A basic calculator may be used.

Complete the quiz independently to obtain a useful indication of your development needs.

Your results support focused learning and investigation practice. Successful completion does not independently verify practical investigation competence or replace the technical review and authorization required for workplace decisions.
