Information System Architecture phase

Information Systems Architecture focuses on identifying and defining the applications and data considerations that support an enterprise’s Business Architecture; for example, by defining views that relate to information, knowledge, application services, etc

Information System Architecture = Data Architecture + Applications Architecture

Data Architecture Inputs

  • Request for Architecture work
  • Org Capabilities, Communication Plan
  • SOW, Architecture Vision, Architecture Repository
  • Data Principles
  • Baseline and Target Business Architecture in Detail
  • Baseline and Target Data Architecture in Vision or Draft
  • Baseline and Target Application Architecture in Vision or Draft
  • Gap Analysis reports
  • Business Architecture Components of EA

Data Architecture Steps

  • Develop baseline and target Data Architectures
  • Perform Gap Analysis
  • Get it reviewed by stake holders

Data Architecture Outputs

  • SOW Updated
  • Validate and update Data principles
  • Update Baseline and Target Architecture Documents based on stake holders review
  • Draft Architecture Documents on Applications and Technology Vision
  • Constraints on Technology if any.

 

Application Architecture Inputs

 

  • Org Capabilities, Communication Plan
  • Request for Architecture Work
  • SOW, Architecture Vision, Architecture Repository
  • Data Principles
  • Baseline and Target Business Architecture in Detail
  • Baseline and Target Data Architecture in Detail
  • Baseline and Target Application Architecture in Vision or Draft
  • Gap Analysis reports
  • Business Architecture Components of EA

Application Architecture Steps

  • Develop baseline and target Application Architectures
  • Perform Gap Analysis
  • Create Architecture Definition Document
  • Get it reviewed by stake holders

Application Architecture Outputs

  • SOW Updated
  • Validate and update Application principles
  • Update Baseline and Target Architecture Documents based on stake holders review
  • Draft Architecture Documents on Applications and Technology Vision
  • Application Interoperability requirements
  • Constraints on Technology if any.
  • Create Architecture Definition Document

Design and Implementation

  • Design:
    • Business Architecture design
    • Data (or Application) Architecture design
    • Application (or Data) Architecture design
    • Technology Architecture design
  • Implementation:
    • Technology Architecture implementation
    • Application (or Data) Architecture implementation
    • Data (or Application) Architecture implementation
    • Business Architecture implementation

Application Architecture Diagrams

Data Model Diagrams

Application Architecture Steps

  1. Select Reference Models, Viewpoints, and Tools
  2. Develop Baseline Application Architecture Description
  3. Develop Target Application Architecture Description
  4. Perform Gap Analysis
  5. Define Roadmap Components
  6. Resolve Impacts Across the Architecture Landscape
  7. Conduct Formal Stakeholder Review
  8. Finalize the Application Architecture
  9. Create Architecture Definition Document

Architecture Definition Doc – Information Sys Arch

  • Baseline Data Architecture
  • Target Data Architecture – Business and Logical Data models
  • Data Management Process ,
  • Data Entity – Business Function Matrix
  • Data Architecture – Stake holders view point
  • Baseline Application Architecture
  • Target Application Architecture – Process, People, Place, Time  – system models
  • Application Architecture – Stake holders view point
