Risk Management Planning Workflow

Establish risk management process per ISO 14971.

Workflow: Create Risk Management Plan

1. Define scope of risk management activities:
   • Medical device identification
   • Lifecycle stages covered
   • Applicable standards and regulations
2. Establish risk acceptability criteria:
   • Define probability categories (P1-P5)
   • Define severity categories (S1-S5)
   • Create risk matrix with acceptance thresholds
3. Assign responsibilities:
   • Risk management lead
   • Subject matter experts
   • Approval authorities
4. Define verification activities:
   • Methods for control verification
   • Acceptance criteria
5. Plan production and post-production activities:
   • Information sources
   • Review triggers
   • Update procedures
6. Obtain plan approval
7. Establish risk management file
8. Validation: Plan approved; acceptability criteria defined; responsibilities assigned; file established

Risk Level Actions

Risk Analysis Workflow

Identify hazards and estimate risks systematically.

Workflow: Conduct Risk Analysis

1. Define intended use and reasonably foreseeable misuse:
   • Medical indication
   • Patient population
   • User population
   • Use environment
2. Select analysis method(s):
   • FMEA for component/function analysis
   • FTA for system-level analysis
   • HAZOP for process deviations
   • Use Error Analysis for user interaction
3. Identify hazards by category:
   • Energy hazards (electrical, mechanical, thermal)
   • Biological hazards (bioburden, biocompatibility)
   • Chemical hazards (residues, leachables)
   • Operational hazards (software, use errors)
4. Determine hazardous situations:
   • Sequence of events
   • Foreseeable misuse scenarios
   • Single fault conditions
5. Estimate probability of harm (P1-P5)
6. Estimate severity of harm (S1-S5)
7. Document in hazard analysis worksheet
8. Validation: All hazard categories addressed; all hazards documented; probability and severity assigned

Risk Evaluation Workflow

Evaluate risks against acceptability criteria.

Workflow: Evaluate Identified Risks

1. Calculate initial risk level from probability × severity
2. Compare to risk acceptability criteria
3. For each risk, determine:
   • Acceptable: Document and accept
   • ALARP: Proceed to risk control
   • Unacceptable: Mandatory risk control
4. Document evaluation rationale
5. Identify risks requiring benefit-risk analysis
6. Complete benefit-risk analysis if applicable
7. Compile risk evaluation summary
8. Validation: All risks evaluated; acceptability determined; rationale documented

Risk Control Workflow

Implement and verify risk control measures.

Workflow: Implement Risk Controls

1. Identify risk control options:
   • Inherent safety by design (Priority 1)
   • Protective measures in device (Priority 2)
   • Information for safety (Priority 3)
2. Select optimal control following hierarchy
3. Analyze control for new hazards introduced
4. Document control in design requirements
5. Implement control in design
6. Develop verification protocol
7. Execute verification and document results
8. Evaluate residual risk with control in place
9. Validation: Control implemented; verification passed; residual risk acceptable; no unaddressed new hazards

Post-Production Risk Management

Monitor and update risk management throughout product lifecycle.

Workflow: Post-Production Risk Monitoring

1. Identify information sources:
   • Customer complaints
   • Service reports
   • Vigilance/adverse events
   • Literature monitoring
   • Clinical studies
2. Establish collection procedures
3. Define review triggers:
   • New hazard identified
   • Increased frequency of known hazard
   • Serious incident
   • Regulatory feedback
4. Analyze incoming information for risk relevance
5. Update risk management file as needed
6. Communicate significant findings
7. Conduct periodic risk management review
8. Validation: Information sources monitored; file current; reviews completed per schedule
