What It Is

ANSI/ISA-95 (IEC 62264) is an international framework for enterprise-control system integration. It organizes manufacturing into Purdue levels 0-4, focusing on interfaces between Level 3 (MES/MOM) and Level 4 (ERP/logistics). Primary purpose: standardize information models, activities, and exchanges to reduce integration risks, costs, errors using hierarchical, object-based models.

Key Components

• Eight parts: models/terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging/aliasing/profiles (Parts 6-8).
• Core: equipment hierarchy, activity models (production, quality, maintenance), object semantics for materials/personnel.
• Built on Purdue Reference Model; no formal certification, but conformance via aligned architecture and training programs.

Why Organizations Use It

Reduces semantic misalignment in IT/OT convergence; enables consistent data for OEE, traceability, analytics. Voluntary but essential for manufacturing digital transformation, regulatory audits, multi-site scalability. Builds stakeholder trust through auditable integrations.

Implementation Overview

Phased: assessment, canonical modeling, pilot (3-6 months), rollout. Applies to manufacturing industries globally; requires governance, master data, security segmentation. No mandatory audits; success via KPIs like integration cost reduction.

What It Is

MAS Technology Risk Management (TRM) Guidelines (revised January 2021) are supervisory guidelines issued by the Monetary Authority of Singapore (MAS) for financial institutions. They provide a principles-based framework for managing technology and cyber risks, emphasizing proportional implementation based on risk profile, complexity, and criticality to ensure confidentiality, integrity, and availability (CIA).

Key Components

• 15 main sections covering governance, risk frameworks, secure development, IT operations, resilience, access controls, cryptography, cyber defense, assessments, and audit.
• Synthesised 12 core principles like board accountability, asset management, third-party oversight, and defence-in-depth.
• No fixed control count; focuses on outcomes with continuous improvement.
• Compliance via supervisory review, no formal certification.

Why Organizations Use It

• Mandatory for MAS-supervised FIs to avoid enforcement (fines, license actions).
• Enhances cyber resilience, operational stability, and customer trust.
• Supports digital transformation while mitigating systemic risks.
• Builds competitive edge through robust governance and evidence-based assurance.

Implementation Overview

• Phased approach: governance setup, asset inventory, risk assessment, control deployment, testing, monitoring.
• Applies to banks, insurers, fintechs in Singapore; scalable by size.
• Involves board approval, CISO appointment, audits; 12-24 months typical.
