Prototyping is an approach that involves creating a working model of the system requested, demonstrating it for the user, obtaining feedback. and making changes to the underlying code. This process repeats through several iterations until the user is satisfied with the system's functionality. Formerly, this approach was derided as being wasteful of resources and tending to produce unstable systems, but with vastly increased processing power and high-productivity development tools. prototyping can, in some cases, be an efficient means of systems development.

The general effect of free trade would be to maximize world output because resources in each country would be deployed most efficiently according to the principle of comparative advantage. Comparative advantage means that a country can produce a greater output of certain goods for a given level of input than other goods. Thus, that country should specialize in and export the goods it can produce most efficiently. Total world output will increase in these circumstances.
