Business Ecology Initiative & Service-Oriented Solution

SOA Reference Architecture Foundation matches VPEC-T

Vote 0 Votes

Some of us know that a year ago CapGemini's Nigel Green and Carl Bate published their great book 'Lost in Translation' where they described a 'language' that was supposed to help in translation from business needs to IT solutions. "This language is called 'VPEC-T after the five dimensions it focuses on: Values, Policies, Events, Content and Trust. VPEC-T is presented as a common language that is natural for both business and IT, and is "straightforward enough to use, yet sophisticated enough to work in today's connected world," - said Nigel Green.

Having the 60-day Public Review of Reference Architecture Foundation for SOA v1.0 (OASIS SOA RAF) available now, let me show how the five dimensions of this 'language' are reflected in the OASIS SOA RAF:

  • Values dimension - is the Real World Effect that may be provided by the service;

  • Policies dimension - is the service Execution Context (for interaction and execution) as well as the governing policies applied during the service creation; policies are listed in the Service Description and Service Contract documents;

  • Events dimension - is the cause of the service use intent, service consideration, service invocation, interaction with the service and may be the part of the service execution; the basic nature of service - the request from the consumer - is the consequence of an event-driven user activities;

  • Content dimension - is not only the service interface exchange data but also the business objectives, goals and offered business functionality that are described with other information in the Service Description and Service Contract documents; content is everything that contributes into obtaining the Real World Effect that carries particular business value

  • Trust dimension - is a relatively complex subject and the OASIS SOA RAF has dedicated several sections to it. Trust is the Business category not much known in Technology beside security authentication/authorisation/encryption. Trust is the foundation for any service invocation because service provider is trusted to help resolve business problems and satisfy business needs. Trust is the fundamental element of any service-oriented eco-system

I invite you to proof my statements by reading the OASIS SOA RAF by yourself... and sending OASIS your comments.
