Overview

The BS ISO/IEC/IEEE 21839:2019 standard is an essential document for professionals in the field of systems and software engineering. It provides comprehensive guidelines and considerations for the life cycle stages of a system, particularly focusing on the concept of System of Systems (SoS). This standard is a critical resource for ensuring that systems are designed, developed, and managed effectively throughout their entire life cycle.

What is a System of Systems (SoS)?

A System of Systems (SoS) is a complex integration of multiple independent systems that work together to achieve a higher-level objective. Each constituent system retains its own management and operational independence, yet they collaborate to deliver capabilities that none of the individual systems can achieve on their own. This standard provides a framework for understanding and managing the unique challenges associated with SoS, such as interoperability, emergent behavior, and lifecycle management.

Key Features and Benefits

• Comprehensive Guidance: Offers detailed insights into the considerations necessary at each stage of a system's life cycle, from conception to decommissioning.
• Interoperability Focus: Emphasizes the importance of interoperability between systems, ensuring seamless integration and operation within an SoS environment.
• Lifecycle Management: Provides strategies for effective lifecycle management, helping organizations to optimize performance and extend the lifespan of their systems.
• Emergent Behavior Analysis: Addresses the challenges of emergent behavior in SoS, offering methodologies to predict and manage unexpected outcomes.
• Global Standardization: As an internationally recognized standard, it facilitates global collaboration and consistency in systems engineering practices.

Who Should Use This Standard?

This standard is invaluable for a wide range of professionals, including:

• Systems Engineers: To design and manage complex systems effectively.
• Software Engineers: To ensure software components are compatible and interoperable within an SoS.
• Project Managers: To oversee the lifecycle stages of systems and ensure successful integration and operation.
• Quality Assurance Professionals: To implement best practices for system reliability and performance.
• Academics and Researchers: To explore new methodologies and frameworks in systems engineering.

Application Across Industries

The principles outlined in the BS ISO/IEC/IEEE 21839:2019 standard are applicable across various industries, including:

• Aerospace and Defense: For managing complex defense systems and aerospace projects.
• Automotive: To integrate advanced automotive systems and technologies.
• Healthcare: For developing interoperable healthcare systems and medical devices.
• Telecommunications: To ensure seamless communication and data exchange between systems.
• Energy and Utilities: For managing large-scale energy systems and smart grids.

Why Choose BS ISO/IEC/IEEE 21839:2019?

Choosing the BS ISO/IEC/IEEE 21839:2019 standard means opting for a robust framework that enhances the efficiency and effectiveness of systems engineering processes.

BS ISO/IEC/IEEE 21839:2019

This standard BS ISO/IEC/IEEE 21839:2019 Systems and software engineering. System of systems (SoS) considerations in life cycle stages of a system is classified in these ICS categories:

• 35.080 Software

1.1 Purpose

This document provides a set of critical system of systems (SoS) considerations to be addressed at key points in the life cycle of the system of interest (SoI). This document refers to considerations that apply to an SoI that is a constituent system that interacts in an SoS. The considerations and life cycle model align with those which are already defined in ISO/IEC/IEEE 15288 and ISO/IEC/IEEE 24748‑1. Selected subsets of these considerations can be applied throughout the life of systems through the involvement of stakeholders. The ultimate goal is to achieve customer satisfaction, so that when delivered, the SoI will operate effectively in the operational or business environment which is typically characterized as one or more systems of systems.

This document concerns those systems that are man-made and are configured with one or more of the following: hardware, software, humans, procedures and facilities.

1.2 Field of application

This document addresses SoS considerations that apply to systems at each stage of their respective life cycles.

There is a wide variety of systems in terms of their purpose, domain of application, complexity, size, novelty, adaptability, quantities, locations, life spans and evolution. This document is concerned with describing the system of systems considerations that apply to a system that is the SoI; that is a constituent system within a system of systems. It applies to one-of-a-kind systems, mass produced systems or customized, adaptable systems.

1.3 Limitations

This document does not detail the approach to addressing system of systems considerations in terms of methods or procedures.

This document does not detail the described documentation in terms of name, format, explicit content and recording media of documentation.
