Risk Assessment Knowledge Center
Practical guidance for assessing manufacturing and quality risks. Learn when to use a risk matrix, how to maintain a risk register, and when to develop a detailed Process FMEA—with worked examples and free tools.
What do you need to assess?
Choose a useful starting point. A broad risk assessment, a single Action Priority calculation and a full Process FMEA answer different questions.
Prioritise broad risks
Discuss quality, delivery and operational exposure with a common likelihood and impact scale.
Own the actions
Record existing controls, mitigation, owners and status so the assessment becomes a working register.
Evaluate one failure scenario
Use evidence-based Severity, Occurrence and Detection ratings to calculate FMEA Action Priority.
Analyse a process in depth
Document failure modes, effects, causes, prevention and detection controls in a full Process FMEA.
Risk Assessment Fundamentals
Start with scope, evidence and a clear decision. These guides explain how to assess a risk, maintain the record and choose the right depth of analysis.
A practical manufacturing guide to scope, evidence, evaluation and follow-up.
Choose the right depth of analysis for an operational risk or process failure.
Risk Matrices & Registers
Set likelihood and impact ratings, interpret scores and understand the limits.
Keep risks, controls, actions and ownership together in a useful working record.
Distinguish the starting assessment, planned improvements and verified remaining risk.
Qhubio’s generic 5×5 matrix supports discussion and prioritisation. Its score bands are not prescribed ISO or IATF acceptance thresholds, and its scores do not convert into FMEA Action Priority.
