Business Process Management, an enduring trend or a passing fad?

Business Process Management (BPM) and its affiliate management technologies like Lean Six Sigma (LSS) and Service Oriented Architecture (SOA) has taken the business world by storm  over the last decade and has underpinned some of the most successful business transformations in history. Some commentators went as far as predicting that companies that do not embrace BPM  and make it a cornerstone of their management practices  will not be able to compete and will ultimately fail. But we have seen many management methodologies come and go in the past. So is BPM just the latest fad or an enduring trend? Let me know what you think.
