Enterprise Architecture has failed in a big way

Ivar Jacobson. Around the world introducing an Enterprise Architecture (EA) has been an initiative for most financial institutions (banks, insurance companies, government, etc.) for the last five years or so, and it is not over. I have been working with such companies and helped some of them to avoid making the worst mistakes. Most EA initiatives failed. My guess is that more than 90% never really resulted in anything useful. ... Many of the companies that failed are now looking for the next silver bullet – Service Oriented Architecture (SOA). To me SOA is what EA should have become. SOA can be described as EA++ -- it is Enterprise Architecture made better. SOA is clearly on the right path, but again adopting it requires that you work smart!
