Just as trade used to follow the flag in the days of the British Empire, so Japanese service companies are following the economic colonists of Japanese industry around the globe: Software Research Associates plans to begin full-scale international operations by opening offices in London and Chicago to complement its New York representative office; it is looking for additional business from existing Japanese customers setting up plants requiring manufacturing control systems – such as Mazda in Chicago – and from financial institutions wanting 24-hour trading systems; a US West Coast office, and joint development projects with universities and research institutions are also in the company’s plan.
