SOA Definition Confusion

After view and review of dozens of dozens of blogs and articles about SOA I concluded that lot of bloggers and writers still defining SOA (Service Oriented Architecture) definition with their own way and every definition are perfect with the respect of respective environments. I want to define SOA in my own words.

“SOA is all about the granularity of Organization IT assets.”

If assets are coarse-grained its mean greater flexibility and reusability of assets across different organization department internally and by external business partners as well. In short term all services should be coarse-grained rather then fine-grain. By coarse-grained we achieve loose coupling between services.

Analysts and architects should consider the following point when they go for SOA project.

Not only create pieces of software (try to break up systems into reusable services).
Select best practices from organizational and technical sides.
Apply new thinking and best practices into project.
Select mature technologies (design models, messaging and architecture services).
Create business-oriented services, later will be utilized in enterprises.
