Mission
The purpose of the Resilient Systems Working Group (RSWG) is to further the understanding of resilience of engineered systems and to provide a clear description of the principles of resilience in INCOSE publications and outreach materials.
Scope
The definition of resilience, as agreed by the RSWG, is that System Resilience is the ability of an engineered system (or System of Systems) to provide required capability when facing adversity.
- The term engineered system is limited to human-made systems containing software, hardware, humans (e.g. socio-technical), infrastructures, concepts, and processes.
- For the purpose of resilience, an adversity is anything that might degrade the capability provided by a system. Achieving resilience requires consideration of all sources and types of adversity; e.g., from environmental sources human, sources, or system failure; from adversarial, friendly, or neutral parties; adversities that are malicious or accidental; adversities that are expected or not. Adversities may be issues, risks, or unknown-unknowns. Adversities may arise from inside or outside the system.
- The fundamental objectives of resilience are avoiding, withstanding, and recovering from adversity.
- The means of achieving these fundamental objectives include Adaptability, Agility, Anticipation, Continuity, Disaggregation, Evolution, Graceful Degradation, Integrity, Preparation, Prevention, Re-architecting, Redeploying, Robustness, Situational Awareness, Tolerance, Transformation, and other methods.
- Resilience focuses on providing required capability – not necessarily with maintaining the architecture or composition of the system.
Goals
- Codify and document the state-of-the-practice for system resilience,
- Investigate, advance, and capture the state-of-the art for system resilience and related topics such as Resilience Modeling for Model-Based Systems Engineering (MBSE), Digital Engineering (DE), and resilience aspects of Loss-Driven Systems Engineering (LDSE).
- Establish a stable systems engineering vocabulary for resilience,
- Collaborate with other INCOSE groups to consistently apply system resilience practice, taxonomies, tools, and techniques
- Develop and support working group products.
