New arrangements are sometimes tried first between a small number of parties. A first case can show how a new framework works in practice.

The New Zealand Government reported that Prime Minister Helen Clark and Chinese Premier Wen Jiabao witnessed the signing of the historic Free Trade Agreement between New Zealand and China.

Why test new frameworks at the perimeter?

New Zealand is the first developed country to negotiate an FTA with China. The stated objective is for the agreement to come into force on October 1, 2008.

For people who design systems, a first agreement of a new kind raises a general question: what can be learned from one case before the same approach is tried elsewhere? The sources do not say what either government intended beyond the agreement itself.

The value of a functional prototype

In general terms, once a new set of rules is written down, it can be observed in use. A first case offers a chance to see how the rules work.

Any agreement between economies of different sizes has to be fitted to both.

A first agreement can also leave questions open. How well its terms work may only become clear after it takes effect, and what one pair of countries agrees does not decide what others will do. Those who study such agreements often look at the text, the timetable and the reactions of the parties before drawing conclusions. A careful reader can note what was signed and when, and leave the rest to later evidence.

One reading is that progress does not always start with the largest step.
