03 Enterprise Continuum

Enterprise Continuum = Architecture Continuum + Solution Continuum What is Continuum Continuum models explain variation as involving a gradual quantitative transition without abrupt changes or discontinuities The Enterprise Continuum provides a consistent language to communicate the differences between architectures so that Architectures and Solutions can be re-used, Also EC is

  • A view of the Architecture Repository
  • Methods for classifying architecture and solution artifacts
  • Re-use a industry standard solution where ever its possible rather than re-inventing a wheel , in other words a Telecom industry has a well established billing software and solution for both its retail , inter connect and value based services , use those solutions ( softwares ) rather than writing your own home grown software solution, this helps in business continuity as you are re-using industry standard experience rather than re engineering your own solution.
  • Some times even the language specific to industry standard counts a lot for example you talk of inter connect billing people in telecom domain understand it , where as if you invent new words to coin the same you would end up confusing the stake holders / partners associated with
  • Generalize a Specific Solution or Customize a Generic Solution based on External factors that influence Architecture Context

Architecture Partitioning

1. Architecture Continuum Architectural Continuum = Foundation Architecture + Common System Architecture + Industry Architecture + Organization Architecture where Foundation Architecture provides direction and strategies for products and services, Very High level, Generic, Common System Architecture create an architecture useful for building common and reusable solutions across a wide number of relevant domains, Some of the examples are Security Architecture, Email Architecture and Network Architecture Industry Architecture is more Industry Specific , for example telecom industry might follow some standards no matter which operator operates in which country, Active Store Arch for Retail Industry, eTOM  for Telecom Industry Organization Architecture is more related to Specific Enterprise or Organization, Tailored for Specific Org Needs, Each Business Divisions might have different needs , and each Divisions might have different Org Specific Architecture. They are more requirement specific, 2. Solutions Continuum Solution Continuum = Products and Services + System Solutions + Industry Solution + Organization Solution example Products : Need to be procured based on Approval chain Services : Need to be top class including In Person Training with Course Material System Solutions : Only Certified and Branded Systems need to be implemented Industry Solutions : Procure Re-usable components from Industry leaders if it is better choice than to develop your own Organization Solutions : Implementation of the EnterpriseArchitecture that provides therequired business functions All working together in Enterprise Continuum

Architecture Repository

  • Architecture Meta Model contains Organizationally Tailored Architecture Model and Content Framework
  • Architecture Capability is all about Skills, Org Structure and Processes that support Governance
  • Architecture Landscape is all Architectural view Building Blocks that are currently running , E.g List of Applications running at present
  • Standard Information base is all about Industry, Business , Data, Application and Technology standards
  • Reference library covers Architecture Continuum , that is foundation architecture, common system architecture, industry architecture, organization specific architecture
  • Governance logs covers, Decision Log, Governance Assessment, Capability Assessment, Project portfolio, performance measurement
