Overview
ISO 14258:1998/Cor 1:2000 is a technical corrigendum to the international standard ISO 14258:1998, published by the International Organization for Standardization (ISO). This corrigendum updates and clarifies definitions and concepts related to industrial automation systems, specifically focusing on enterprise models. These models are crucial for representing the structure, behavior, and purpose of enterprises to improve effectiveness, efficiency, and integration of information systems.
The standard serves as a foundational document for enterprises seeking to adopt or refine enterprise modeling practices within industrial automation, aligning with system theory and providing a framework for modeling high-level activities and life-cycle processes.
Key Topics
- Enterprise Definition: Revised as a group of organizations sharing goals to offer products or services.
- System Complexity: The corrigendum addresses uncontrollable systems where decision-making procedures are not feasible.
- Modeling Constraints: Recognition of internal and external restrictions that influence system and model design.
- Enterprise Model Purpose: Models represent what an enterprise seeks to achieve, how it operates, and potentially how it is organized, supporting integrated information system requirements.
- System Theory Terminology: Updated from "systems theory" to "system theory" for accuracy.
- Lifecycle Activities: Introduction of three recursive and iterative activities essential for system life-cycle phases:
- W (What): Determining what needs to be done.
- H (How): Identifying how to accomplish tasks.
- D (Do): Executing the planned activities.
- Hierarchy Structures: Use of part-of and kind-of hierarchies to classify and decompose enterprise elements.
- Behavioral Modeling: Emphasizes capturing sequentiality, events, states, and time-related dynamic performance within enterprise processes.
- Modeler’s Role: Defines the enterprise modeler as an observer tasked with explicitly stating the model’s purpose and constraints.
- Function View: Representation of activities and processes emphasizing system behavior and interdependencies.
Applications
- Enterprise Integration: Facilitates integration of processes and information flows across organizational boundaries to optimize manufacturing and production.
- Process Improvement: Supports iterative feedback within system life-cycle phases to enhance product quality and enterprise flexibility.
- Information System Design: Provides insights into defining requirements for integrated information systems supporting enterprise operations.
- System Lifecycle Management: Helps enterprises manage plan/build, use/operate, and recycle/dispose phases using W, H, D activity framework to streamline operations and redesign.
- Model Interoperability: Ensures different models of enterprise activities can communicate effectively to support comprehensive decision-making.
- Behavioral Analysis & Simulation: Enables enterprises to simulate processes and evaluate performance using time-related and sequential behavior models.
- Hierarchical Modeling: Allows for scalable enterprise modeling with clear classification and decomposition of enterprise components.
Related Standards
- ISO/TC 184 - Industrial Automation Systems and Integration: The technical committee responsible for this standard, covering architecture, communications, and integration frameworks.
- System Theory Standards: Frameworks and standards related to system behavior, modeling, and lifecycle management that complement ISO 14258.
- Enterprise Architecture Standards: Other ISO standards and frameworks designed to support enterprise modeling and process integration such as ISO 15704 for enterprise-reference architectures.
ISO 14258:1998/Cor 1:2000 provides practical guidance for organizations aiming to enhance their enterprise modeling capabilities within industrial automation, promoting clear definitions, lifecycle activities, hierarchical structuring, and comprehensive descriptions of enterprise behavior. Its corrections update critical definitions and promote interoperability and effective enterprise process integration.
