Some companies have expensive development teams dedicated to the various foreign languages.
A few companies build a large and inefficient staff of localizers who do manual software localization as they try and keep up with english development. Many send their work to software localization agencies and must also pay an internal support staff to monitor vendor progress and fix vendor problems. The Better Way At Corel, IPS took the localization head count for the WordPerfect Suite from over 100 employees to 13 employees. To the amazement of the large vendors, we did all the localization engineering with 10 engineers using the what is now, the heart of the IPS sotware localization technology. In addition, the only outsourcing necessary was the actual software translation work.
