Severity is the rating of consequence impact if a failure mode occurs - It reflects downstream business, safety, and customer impact.

What Is Severity?

• Definition: the rating of consequence impact if a failure mode occurs.
• Core Mechanism: Severity scoring assesses effect magnitude independent of how often failure occurs.
• Operational Scope: It is applied in manufacturing-operations workflows to improve flow efficiency, waste reduction, and long-term performance outcomes.
• Failure Modes: Inconsistent severity criteria across teams weakens FMEA prioritization.

Why Severity Matters

• Outcome Quality: Better methods improve decision reliability, efficiency, and measurable impact.
• Risk Management: Structured controls reduce instability, bias loops, and hidden failure modes.
• Operational Efficiency: Well-calibrated methods lower rework and accelerate learning cycles.
• Strategic Alignment: Clear metrics connect technical actions to business and sustainability goals.
• Scalable Deployment: Robust approaches transfer effectively across domains and operating conditions.

How It Is Used in Practice

• Method Selection: Choose approaches by bottleneck impact, implementation effort, and throughput gains.
• Calibration: Use shared severity scales with example anchors and governance review.
• Validation: Track throughput, WIP, cycle time, lead time, and objective metrics through recurring controlled evaluations.

Severity is a high-impact method for resilient manufacturing-operations execution - It sets impact weighting in risk-prioritization frameworks.
