Despite the hassle that travelers worldwide have to put up with, I don’t think it is a good idea to ask the United Nations to enforce global standards for sockets, currencies, and measurement systems. Different parts in a complex system will always try to optimize for themselves, and therefore local systems will switch to global standards when it is optimal for them to do so. This is exactly what happened in Europe: 16 European countries voluntarily switched to a new pan-European currency because they figured that the opportunities and long-term cost savings were higher than the one‑time switching costs. Some other European countries have not (yet) taken this step because their perceived costs (financial, political, and cultural) are apparently still higher than the benefits.
Standardization is usually not something that needs to be enforced. No worldwide government was necessary to make billions of people around the world to standardize on the 24-hour clock, the Gregorian calendar, the English language, or Right-hand traffic. True, there are plenty of deviations from the international standards. Positive feedback loops will only lead to adoption of standards when it pays to do so.
After choosing our activities, we begin to perform them. As we do so, the next event in self-management comes into play – monitoring our performance for competence. This event, then, involves making sure that our work activities meet our standards. During the compliance era, work standards were external and set by managers at fixed levels. Workers were charged with doing work that met these levels – doing “good enough” or “satisfactory” work. In contrast, self-management involves committed workers meeting their own internal standards of competence. Internal standards are more dynamic: people raise their standards on tasks they care about as they become more skilled and experienced at the task activities. – Intrinsic Motivation at Work (Kenneth Thomas)
In software development, competence leaders work with people to discuss their own internal standards, not management-imposed standards. Like naming conventions, coding standards, user interaction conventions, file structures, configuration management practices, tools, error log standards, and security standards. There is no need for management to make top-down standardization happen. Bottom-up standardization will happen when goals and metrics make it painfully clear for employees that it is more optimal for them to change.
