When The Agreement Outlives Its Own Good Sense

The same stability that makes a standard valuable makes it hard to leave behind.

Every standard freezes an approach. That is what it is for. The freeze is what lets other people build on top without worrying that the ground will move. But the world does not stop, and eventually the frozen approach is no longer the best approach, and then the standard is holding in place something that a fresh design would not choose. The mechanisms that give a standard its value are the same mechanisms that make it difficult to displace, and there is no way to keep the first property while discarding the second. Stability and adaptability are drawing on the same account.

Standards bodies know this and build against it. Documents come up for systematic review at intervals, and are confirmed, revised or withdrawn, and withdrawal is a real outcome rather than a theoretical one. Revision is continuous in active fields. But revision is bounded by backward compatibility, because a revised document that breaks everything built to the previous one will not be adopted, and so the revisions tend to accrete rather than replace. Old decisions survive inside new documents as accommodations, quirks and reserved values that nobody would design today, carried forward because too much depends on them.

The deeper limit is what a standard can express at all. A document can say precisely what a dimension must be and can be checked against a measurement. It can describe an arrangement of work, and somebody can compare an organisation to the description. What it cannot do is specify judgement, care, or the quality of thought a person brings to a difficult decision at an awkward moment. Standards are extraordinarily good at making the world consistent. They are much weaker at making it wise, and pretending otherwise is the most common mistake made in their name.
