What this unit settles

The existence of Annex B is itself the public evidence that significance is a judgement the document expects a practice to make and record. A firm that treats every design decision as architecturally significant has no priority; a firm that treats none as significant has no architecture governance.

What to do in your practice

Write the significance criteria the firm will use: value, whole entity reach, endurance and cost of reversal. Test them on recent decisions and record the outcome. Publish the criteria with the decision process. Publish the criteria and the classification of the last twenty decisions together. The pairing lets a reader test the criteria against real cases, and it turns a philosophical argument about significance into a calibration exercise the practice can repeat each year.

Who it binds

The architecture practice, as a note. The public preview does not state the annex status, so this page does not claim one.

Evidence an auditor or regulator asks for

  • The significance criteria and their tests.
    An auditor asks how a decision was judged significant.
  • A sample of decisions classified against the criteria.
    Proves the criteria are applied.
  • The record of decisions escalated and not escalated.
    Shows the filter works both ways.
  • The review date.
    Keeps the criteria current.
Ask your teamWhat test does this firm use to decide that a design decision is architecturally significant?

Common gaps this page catches

  • Every decision is escalated, so the architecture board is a bottleneck.
  • No criteria exist, so significance is political.
  • The filter is applied inconsistently across teams.

What to prepare before publication

Write the criteria and test them on the last twenty decisions. Record the classification. Adjust the criteria where the result is implausible, not the decisions.
