Overview
IEC 62853:2018 is an international standard developed by the International Electrotechnical Commission (IEC) focused on open systems dependability. It provides comprehensive guidance on the set of requirements for managing system life cycles to achieve dependable open systems. Building upon the foundational principles of IEC 60300-1 and aligned with the system life cycle processes defined in ISO/IEC/IEEE 15288:2015, this standard addresses the unique challenges posed by open systems-where hardware, software, and human components dynamically interact and evolve.
Key to its scope is improving the dependability of products, systems, processes, and services operating as open systems, which require heightened attention to security due to their high vulnerability to attacks. IEC 62853:2018 offers organizations a structured approach to defining necessary activities and tasks to meet dependability objectives throughout the system life cycle.
Key Topics
-
Open Systems Characteristics
Open systems are dynamic entities with changing boundaries, functions, and structures over time. They are described from multiple perspectives, requiring specialized processes for dependability management.
-
Dependability in Open Systems
The standard highlights dependability issues specific to open systems, emphasizing security and resilience to failures and attacks as critical factors for sustained operation.
-
Process Views for Dependability
IEC 62853:2018 defines detailed process views aligned with ISO/IEC/IEEE 15288, enabling organizations to:
- Build consensus among stakeholders regarding dependability requirements.
- Achieve accountability through clearly defined responsibilities and actions.
- Develop robust failure response strategies to mitigate and recover from system faults.
- Accommodate changes efficiently to maintain system dependability despite evolving environments.
-
Life Cycle Integration
The standard applies to life cycles of integrated combinations of hardware, software, and human aspects. It supports life cycle models such as Dependable Engineering for Open Systems (DEOS) and Warranty Chain Management (WCM).
-
Assurance and Evaluation
It facilitates dependability assessment and evaluation, helping organizations provide assurance that open systems meet their dependability objectives consistently over time.
Applications
IEC 62853:2018 is essential for organizations involved in the development, operation, and maintenance of complex open systems where dependability is critical. Practical applications include:
-
Telecommunications and Networked Systems
Ensuring reliable, secure operation in systems with changing network topologies and components.
-
Smart Grids and Energy Systems
Managing interconnected devices and services within dynamic power distribution networks to maintain dependable service.
-
Information Technology and Software-Intensive Systems
Addressing hardware-software-human integration challenges to assure continuous operation and resilience.
-
Industrial Automation and Control Systems
Enhancing system safety and fault tolerance during rapid system evolution and deployment of new technologies.
-
Critical Infrastructure
Supporting resilience and accountability in systems critical to societal functions, such as transportation, healthcare, and public safety.
By implementing IEC 62853:2018, organizations can systematically improve the dependability of open systems, minimize downtime, strengthen security posture, and build stakeholder confidence.
