All Rights reserved. 7-Mar-2006 Building (in)flexible business systems (2) • When you’ve finished, you have this big, rigid, monolithic thing that has one very specific purpose Its hard to change the shape There are no identifiable parts that could be re-used for something else If you try, it breaks SOA & BPM 5 SOA & BPM Copyright ©2006, Object Management Group.

The first cost $100m, equal to 7 per cent of business investment at the time. The last cost $2,000bn, or 47 per cent. The next would have cost $5,000bn but we have run out of money: we have come to the end of history as we know it.” Paul A.
