Technical standards provide the syntax for all technical communications. The level of technical standards (number system, measurement system, monetary system, navigational references, communication systems, and process systems) that emerge in each tribe or society is an indicator of its technical sophistication and technological attainment. Technical standards appear to be inherent in all complex systems, to be fundamental to almost all forms of commerce, and to be required for any communications. The process of creating a technical standard is termed standardization.
