B.4:2 - Problem

Without a canonical, shared model for evolution, projects fall into predictable and costly failure modes:

  1. Design-Reality Divergence (The “Drift”): The run-time subject in use slowly diverges from its design-time account. Formal models become elegant fictions, assurance cases become irrelevant, and the project loses the ability to reason reliably about what it uses.
  2. Learning Stagnation (The “Ivory Tower”): Observation produces valuable findings, but no explicit change path carries them into a revised design or renewed use. “Lessons learned” remain static documents.
  3. Chaotic Change (The “Whack-a-Mole”): Reactive patches have no stated observed basis, identity decision, or return-to-use condition. Hidden dependencies and unintended consequences accumulate.
