It is clear now that the more people who use data analysis tools, the more money Toyota can earn. The TLS system was upgrade in 2003 and 2005, and tools are continuously added as needed. Thanks to the new TLS system and other BI, the parent company, Toyota Motor Corporation, reached the highest profit margin in the automotives industry in 2003. Also, Toyota’s market share has increased consistently. (Incidentally, Toyota, which is an agile company, will start to produce consumer-helping robots-that is, service robot for the elderly-in the year 2010.)
