ISA 95 Details
What It Is
ANSI/ISA-95 (IEC 62264) is an international framework for integrating enterprise business systems with manufacturing operations. It defines models for information exchange between Level 3 (MES/MOM) and Level 4 (ERP/logistics), using a Purdue hierarchical approach across Levels 0-4.
Key Components
- Hierarchical levels and equipment models (Enterprise > Site > Area > Unit)
- Activity models (production, quality, maintenance, inventory)
- Object models for materials, personnel, production
- Eight parts covering terminology, transactions, messaging, aliases
- No formal certification; compliance via alignment and self-assessment
Why Organizations Use It
Reduces integration risks, costs, errors; enables semantic consistency for IT/OT collaboration. Supports regulatory traceability, OEE improvements, Industry 4.0 scalability. Builds stakeholder trust through auditable data flows and governance.
Implementation Overview
Phased approach: assess gaps, define canonical models, pilot integrations, rollout with governance. Applies to manufacturing firms globally; involves modeling, middleware, security segmentation. Focuses on data stewardship and change management.
AS9110C Details
What It Is
AS9110C (AS9110:2016 Rev C) is an international quality management system (QMS) standard for aviation maintenance organizations, such as repair stations and MRO providers. It builds on ISO 9001:2015 with aviation-specific requirements for continuing airworthiness, using a risk-based thinking approach via Annex SL high-level structure and PDCA cycle.
Key Components
- Core clauses 4–10 covering context, leadership, planning, support, operation, evaluation, improvement.
- Aviation additions: configuration management, counterfeit parts prevention, human factors, traceability, external provider controls.
- Follows IAQG 91xx family; certification via accredited bodies with OASIS listing.
Why Organizations Use It
- Meets customer/OEM contracts and regulatory alignments (FAA/EASA Part 145).
- Mitigates safety risks, ensures traceability for airworthiness.
- Enhances market access, on-time delivery, customer satisfaction; reduces rework and incidents.
Implementation Overview
- Phased: gap analysis, process design, training, internal audits, certification (6-12 months typical).
- Applies to MROs globally; requires operational evidence pre-certification.
