Human Factors and Competency Management

AS9110 incorporates specific requirements for managing human factors in maintenance operations, recognizing human error as a significant risk factor. Organizations must demonstrate controlled processes for personnel training, competency assessment, and ongoing qualification maintenance.

Conducting an Effective ISO 9001 to AS9110 Gap Analysis

Phase 1: Initial Assessment and Team Formation

Begin by assembling a cross-functional team including representatives from quality assurance, maintenance operations, regulatory affairs, training, and senior management. Establish clear project timelines and assign specific responsibilities for each phase, planning for a comprehensive evaluation period.

Phase 2: Document Review and Requirement Mapping

Conduct a systematic review of AS9110C requirements against your current ISO 9001 documentation. Map each AS9110 requirement to existing procedures to identify specific gaps, categorizing findings as full compliance, partial compliance, or non-compliance for prioritization purposes.

Phase 3: Process Evaluation and Risk Assessment

Evaluate current maintenance processes against AS9110's enhanced requirements for process control and risk management. Conduct interviews with key personnel to understand how processes actually function versus documented procedures, identifying training needs and areas requiring formalization.

Phase 4: Supplier and External Provider Assessment

Review supplier management processes against AS9110's enhanced requirements. Evaluate existing supplier agreements, performance monitoring systems, and external providers' capabilities, particularly those providing services for safety-critical applications.
