SYSE.17:3 - Forces

Recurring tensions include:

  • Consequences can cross, for example, contractual, ownership, organizational, interface, and project boundaries.
  • Early choices need expert judgement; exhaustive measurement is often unavailable or uneconomic.
  • A weakly supported possibility can justify a cheap probe or reversible design, but not an observed-effect claim.
  • A descriptive consequence claim, a value judgement, and a deontic or governance claim use different predicates and evidence.
  • Constituent, containing, neighbouring, and later reidentified Systems can change differently; aggregates can hide those distributions.
  • Specialist safeguards must inform the engineering decision without Systems Engineering claiming authority it does not have.
