SOA, WS and Business

I have spent some time thinking about SOA and the possibility of an adaptive well defined enterprise. In my discussions with people I continually hear SOA and WS used interchangeably. While I understand why WS can be mistaken for SOA, SOA is not Web Services and Web Services are not SOA. SOA is a architectural style that encompasses more than just services. If consumers of technology are going to be successful the architectural style of SOA must converge in a way that allows business people to drive change across the enterprise. The implementations of SOA may include the use of Web Services but there is nothing requiring them.

Oh and one more thing WSDL was NEVER meant to be read by a human. Business people should be looking at contracts not WSDL.

The wisdom of Crowds By: James Surowiecki

I have now completed my second reading of The Wisdom of Crowds: Why the Many Are Smarter Than the Few and How Collective Wisdom Shapes Business, Economies, Societies and Nations. I found the book fascinating and insightful. The book provides a great deal of support for the idea that given the proper conditions a crowd will almost always be smarter that any individual over time. For a crowd to achieve the highest intelligence it must be diverse, be composed of independant parts, decentralized and provide for aggregation of group knowledge. One of the examples given in support of the wisdom of crowds was the search for the USS Scorpion conducted by John Craven. The story of craven and his search can be found in more detail in “Blindman’s Bluff” by Sherry Sontag, Christopher Drew and Annette Lawrence Drew.

Good bye Moveable Type

It was a great trip while it lasted. Moveable Type is a good commercial product. It may well be the best commercial product, but it is not free. I am not opposed to commercial software. I like products that provide the lowest barrier to innovation.

I also feel that Six Apart distributed Moveable Type like a drug dealer distributes to prospective customers. Thats just my opinion. It was shrewd marketing but not very comfortable.

It was a nice ride.

I wish Moveable Type well and future sucess.
