What is BS EN IEC 62853 - Open systems dependability about?
BS EN IEC 62853 provides guidance about a set of requirements placed upon system life cycles for an open system to achieve open systems dependability. BS EN IEC 62853 elaborates on IEC 60300-1 by providing details of the changes needed to accommodate the characteristics of open systems. BS EN IEC 62853 defines process views based on ISO/IEC/IEEE 15288:2015, which identifies the set of system life cycle processes. BS EN IEC 62853 applies to life cycles of products, systems, processes, or services involving hardware, software, and human aspects or any integrated combinations of these elements. For open systems, security is especially important since the systems are particularly exposed to attack.
BS EN IEC 62853 can be used to improve the dependability of open systems and to provide assurance that the process views specific to open systems achieve their expected outcomes. BS EN IEC 62853 helps an organization define the activities and tasks that need to be undertaken to achieve dependability objectives in an open system, including dependability-related communication, dependability assessment, and evaluation of dependability throughout system life cycles.
Who is BS EN IEC 62853 - Open systems dependability for?
BS EN IEC 62853 on Open systems dependability is useful for:
- Government agencies
- Corporate organizations
- Non-profit organizations
- Business enterprises
- End-users, customers, and owners
- Software designers
Why should you use BS EN IEC 62853 - Open systems dependability?
Open systems are systems whose boundaries, functions, and structure change over time and which are recognized and described differently from various points of view. The dependability of open systems is a key attribute for the life cycle of a system that operates for an extended period of time in a real-world environment. Open systems dependability is the ability of open systems to accommodate changes in purpose, objectives, environment, and actual performance and to continuously maintain accountability from stakeholders, to provide expected services as and when required. For open systems, security is especially important since the systems are much exposed to attack by malware. Since an open system changes continuously throughout its life, the design process, e.g., modelled by the spiral product development model, will to some extent continue during the whole lifetime of the system.
BS EN IEC 62853 elaborates on IEC 60300-1 by providing additional guidance for the dependability management of open systems. BS EN IEC 62853 guides open systems dependability by using the four process views, each of which selects and combines system life cycle processes, activities, and tasks of ISO/IEC/IEEE 15288: 2015. BS EN IEC 62853 includes:
- Change Accommodation process view
- Accountability Achievement process view
- Failure Response process view
- Consensus Building process view
A dependability case that assures these process views is crucial for stakeholders to understand and agree on the boundaries of their responsibilities, to assign accountability for implementation, and to duly manage changes in achieving open systems dependability.
