Resilient Systems Working Group

Working to deliver capability when faced with adverse conditions

Working Group Purpose & Mission

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

1. Codify and document the state-of-the-practice for system resilience,

2. Investigate, advance, and capture the state-of-the art for system resilience and related topics such as Loss-Driven Systems Engineering (LDSE) and Resilience Modeling for Model-Based Systems Engineering (LDSE) and Digital Engineering (DE),

3. Establish a stable systems engineering vocabulary for resilience,

4. Collaborate with other INCOSE groups to consistently apply system resilience practice, taxonomies, tools, and techniques,

5. Develop and support working group products.

Outcomes

The primary products are:

  • INCOSE Systems Engineering Handbook (SEH) sections regarding System Resilience
  • INCOSE Systems Engineering Body of Knowledge (SEBoK) sections regarding System Resilience and related topics
  • INCOSE Vision sections regarding System Resilience and related topics
  • Other special publications, e.g. INCOSE Insight issues, Systems Resilience Primer

IW2025: International Workshop Focus

The RSWG will achieve the following fundamental objectives at this INCOSE International Workshop:

  • General Discussion / Business Meeting to accomplish planning of RSWG activities for 2025, including development of a Resilience Primer

  • Review and update the:
  • Resilience sections of the Systems Engineering Body of Knowledge (SEBoK): Resilience Engineering, Resilience Modeling, and Loss-Driven Systems Engineering (LDSE)
  • Resilience Elevator Speech
  • Summary of How to Justify Resilience
  • Database of Things that Frustrate Resilience
  • RSWG Standard Briefing (e.g., History of Resilience, Environmental)
  • Techniques for achieving resilience (i.e., Taxonomy Layers 2 and 3) e.g., Robustness, Recovery
  • Collaborate with other Working Groups regarding resilience concepts, methods, and tools



Planned Activities

  1. Achieve RSWG Work Products (as shown in "Planned Work Products")
  2. Achieve RSWG Team Video & LDSE Video
  3. Continue Weekly RSWG Meetings (1 hour Zoom every Wednesday at 2 PM Eastern Time)
  4. Plan IS2025 Participation
  5. As needed, peer review of Papers and Dissertations that include aspects of resilient systems (includes creation of peer-reviewed papers)
  6. Contribute Resilience Engineering & LDSE papers to SE Journal, INCOSE International Symposia, other venues & journals
  7. Collaborate and participate with other INCOSE WGs and functions to consistently apply system resilience practice, taxonomies, tools, and techniques; capture the state-of-the-practice and advance the state-of-the-art in system resilience and related topics
  8.  Outreach & liaison with other groups, e.g. IEEE, AIAA, ISO/IEC, etc.

Resilient Systems Engineering "Elevator Speech"

  • Systems are made up of parts that are brought together to do something useful.
  • Creating effective systems is not simple!
  • Systems engineering is the method (or process, art, skill, science, discipline) of creating effective systems. 
  • And if you need a system you can count on in rough situations, the systems engineer will apply design techniques known to make the system resilient.
  • So, if you are developing a system, you need to identify the challenges it could face and decide how resilient you need the system to be. It’s about reasonable planning for situations beyond the normal operating conditions of the system.
  • Resilience Engineering not only helps to design for when disasters strike or systems get overloaded, it also helps to figure out how to survive and recover.

Planned Work Products

  1. Review and harmonize INCOSE Systems Engineering Handbook (SEH) sections that address System Resilience
  2. Update SEBoK sections regarding System Resilience and LDSE
  3. Coordinate/harmonize other SEBoK sections that address System Resilience & LDSE
  4. Review and update INCOSE Vision 2035 sections regarding System Resilience and related topics
  5. Develop a Systems Resilience Primer
  6. Intro to RSWG Team Video and Intro to LDSE Video
