  6. Resilient: Replace circa 1920 Upper airplane lost one of its wheels. Gladys Ingles installing a replacement wheel in flight. With the replacement wheel strapped to her back she rides the wing of a rescue plane to the plane that lacks the wheel. She transfers from wing to wing. Expertly works herself down to the undercarriage only a few feet from a spinning prop.   She installs the wheel then stands on the wing of the repaired plane to a successful landing. http://www.oshkosh365.org/ok365_DiscussionBoardTopic.aspx?id=1235&boardid=147&forumid=180&topicid=5584

  7. Current Views • S. Jackson - INCOSE Resilient Systems WG “…the capability of a system with specific characteristics before, during and after a disruption to absorb the disruption, recover to an acceptable level of performance, and sustain that level for an acceptable period of time.“ • R. Dove – INCOSE Systems Security Engineering WG “Sustaining system functionality in the face of intelligent determined attack requires self preservation capabilities that adapt and evolve with equal intelligence, determination, and strength of community.” • B. Sauser, et al: Internal failures. External disruptions. Brian Sauser, Mo MansouriMayada Omer, Using Systemigrams in Problem Definition: A Case Study in Maritime Resilience for Homeland ©Jack Ring.

  39. 1: Competency in Language of SE “We (animals having a frontal lobe) started using our language for reasoning before we learned to use our language for the purpose of communicating with one another. …The correct use of propositions and chains of propositions is critical to appropriate adult behavior.” “Language and Human Behavior,” Prof. Derek Bickerton, U. of Washington Press, 1995, Human language and knowledge is: Extensible in both facts and propositions, apparently without limit. The source of our unique, powerful abilities of abstraction, imagination, synthesis and prescription. Linear, Associative, Janusian, Hegelian, ? ©Jack Ring. Attributed copies permitted

  48. 5. The Reflective Practitioner Four ascending levels of behavior: 1. Know how. 2. Reflection -- on how 'know how' was applied. 3. Knowing-in-action (devising while doing) • Reflection-in-action. A Practitioner must have two kinds of knowing: • Objectivist - descriptive • Constructivist – prescriptive - world making Designing cannot be taught -- but can be coached Designing: knowledge-in-action, holistic, honors unspecified (unspecifiable?) design qualities (aesthetics) Methods of Coaching The Reflective Practitioner • Joint experimentation, • Follow Me! • Hall of Mirrors Educating the Reflective Practitioner, Donald Schon, Jossey Bass, 1987 ©Jack Ring.

  49. Take-aways? • System IS, DOES, KNOWS (some even LEARN!). • Problem Systems, Problem Suppression Systems, Gestation Systems (SE and EofS) • At least 9 categories of resilient systems. • SE, a gestation system, reduces EVA for the E of S cadre • By people, • Pursuing MOE’s @ standard of care by requisite variety. • Achieving knowledge exchange and choice making • Using coherent language, appropriate interpersonal style, and proactive, mutual error detection and correction. ©Jack Ring.
