- Practices categorized as 14 general management, 17 service management, 3 technical management.
- **Four dimensionsOrganizations/people, information/technology, partners/suppliers, value streams/processes.
- Certification model from Foundation to Managing Professional/Strategic Leader via PeopleCert.
Why Organizations Use It
- Delivers cost savings, reduced downtime, 87% global adoption for alignment and ROI (up to 38:1).
- Mitigates risks like $3M data breaches; integrates DevOps/Agile.
- Boosts customer satisfaction, career development, stakeholder trust.
Implementation Overview
- Phased 10-step roadmap: assessment, gap analysis, tailoring, training, tool integration (e.g., CMDB).
- Applicable to all sizes/industries; voluntary with high customization for SMEs/enterprises. (178 words)
ISA 95 Details
What It Is
ISA-95 (ANSI/ISA-95, IEC 62264) is an international standard framework for integrating enterprise business systems like ERP with manufacturing operations and control systems like MES. Its primary purpose is reducing integration risks, costs, and errors through shared models and interfaces, focusing on the Level 3-4 boundary in the Purdue hierarchy.
Key Components
- Eight parts covering models, terminology (Part 1), objects/attributes (Parts 2/4), activities (Part 3), transactions (Part 5), messaging (Part 6), aliases (Part 7), and profiles (Part 8).
- Core Purdue levels 0-4 and equipment hierarchies.
- No formal certification; compliance via architectural alignment and training programs.
Why Organizations Use It
- Drives semantic consistency, faster integrations, and data governance.
- Enables IT/OT collaboration, regulatory traceability, cybersecurity segmentation.
- Improves OEE, reduces downtime, supports Industry 4.0 scalability.
Implementation Overview
- Phased: assessment, modeling, pilot (3-6 months), rollout (12-24 months).
- Involves governance, canonical models, alias mapping; suits manufacturing industries globally.
