antifragile enterprise lexicon
  • a

  • activity
    the condition in which things are happening or being done
  • activity refactoring
    a refactoring of an activity that reduces an optionality constraint caused by the activity
  • agile
    Having the ability to move and change direction quickly and efficiently in response to feedback.
  • b

  • boundary
    the interaction space between dependent entities
  • boundary refactoring
    a modification of a boundary that reduces an optionality constraint caused by the boundary's features
  • boundary smell
    an observable property or behavior that suggests an unhealthy optionality constraint across a boundary
  • c

  • causal distance
    The number if intermediate agents between a cause and an effect. When a cause has a direct effect, the causal distance is zero.
  • causal opacity
    the inability to ascertain cause and effect as a result of complexity.
  • consumer
    an entity that invokes the function of a supplier.
  • e

  • entity
    A thing with distinct and independent existence. In the context of The Antifragile Enterprise, entities are usually consumers and suppliers.
  • extended disorder family
    (i) uncertainty, (ii) variability, (iii) imperfect, incomplete knowledge, (iv) chance, (v) chaos, (vi) volatility, (vii) disorder, (viii) entropy, (ix) time, (x) the unknown, (xi) randomness, (xii) turmoil, (xiii) stressor, (xiv) error, (xv) dispersion of outcomes, (xvi) unknowledge.

  • f

  • fragile
    easily broken or harmed by the extended disorder family.
  • function
    a purpose natural to or intended for an entity or thing
  • o

  • O3 Thinking
    a specialized version of Toyota A3 Thinking that focuses on solving optionality problems
  • option-boundary
    a boundary where one side is a consumer, the other side is a supplier, and there is potentially a many-to-many correspondence between requests and fulfillment options
  • option boundary
    the boundary between a consumer and supplier where different implementation options may exist to fulfill the supplier function or different consumers may exist that invoke the function.
  • optionality
    the asymmetric payoff that results from efficiently creating, culling, and exercising options
  • p

  • postcondition
    a boolean condition that is met after a transformation is complete
  • precondition
    a boolean condition that is required or expected before a transformation
  • r

  • refactoring
    a named small and explicit transformation that specifies the preconditions and postcondition that the transformation satisfies
  • s

  • supplier
    an entity that fulfills a function invoked by a consumer.
  • system
    a set of interdependent functions
