To develop a repository containing details of how the business operates linked to the supporting data and IT architecture.
• Key PrinciplesIn developing the EA Repository the following core principles have been applied:- Common goal and objectives- Common governance framework (methods, standards, roles &
responsibilities)- Common training framework - Common access to information - Single repository of information
• Related Activities- Process Improvement- Portfolio Management- Data Governance and Quality- Governance, Risk and Compliance
• Implement an Enterprise Architecture (EA) Repository using one of the currently-existing tool sets available within EDF
• Establish a set of common standards and ways of working to ensure consistency of approach
• Select an EA tool to support the EA Repository• Establish a set of common standards and ways of working to ensure
consistency of approach• Support strategic decision making using content from Repository• Provide ongoing support to projects to exploit the opportunities available
• Lack of senior stakeholder buy in to EA concepts and value• Lack of business buy in to EA value• Lack of vision around EA concepts and value• Inconsistent model for capturing Architecture content• Disparate EA toolsets in use across EDF Energy• Architecture collateral captured in project documents, document
directories etc.• Lack of re-use of Architecture collateral• Poor communication of Architecture content to stakeholders• Issues with the implementation of EA tools in EDF Energy• Inconsistent modelling standards in place with no governance model to
Build• Project initiated to start development of repository, deliveries included:
• Selection of EA Tool• Mandate defined by Senior Management for all projects to use Repository• Delivery of baseline technical platform• Delivery of baseline standards, support model and reference content•Business and IT Architects trained in use of tool• Definition of Support model• Delivery of baseline web content framework
Embed • Embed the use of the Repository within ESCS•Small Scale adoption of Repository across ESCS on projects •Development of Governance and change control model•Revision of standards and training materials
Enrich •Increase the maturity and scale of Repository usage across ESCS•Develop Strategy level content for Business, IT and Data Architecture across ESCS•Develop ESCS capability for modelling and using the Repository•Develop ESCS learning materials for Repository e.g. lunch n learns, training•Widescale usage of Repository to support ESCS projects
Excel •Exploit the content lodged within the Repository to support ESCS Strategic Ambitions and projects•Deliver means for exploiting content in Repository to support strategic planning•Continue to develop ESCS Capability to use Repository•Embed within relationships with Partners
We have developed an Enterprise Architecture Framework to demonstrate each level of the Architecture, the roles involved and what models you are likely to use.
Building - IT & Data ContentCity PlanningCity planning consists of grouping the different applications used in the information system into different taxonomies
.
An application is a set of software tools as seen from the software development viewpoint.
Application Overviews
Application Overviews present the enterprise's main applications and the interactions between these applications.An Interaction represents the exchange of information between organizational entities of the system.
Technical Infrastructures
A technical infrastructure is defined by the set of equipment and hardware necessary to run applications and to enable communication between these applications according to their distribution on deployment sites
Application Environment
Data Dictionary
Application TreeThe Application Tree Diagram is used to identify the breakdown of an application into its components:
-sub-applications at the higher level
-services implementing functionalities at the lower level)
The Application Environment Diagram is used to place the application in its environment without considering its internal architecture. We focus on the applications interactions with the rest of the world (other Applications, org-Units, communications).
The dictionary is a set of defined terms with definitions written in business language. The main aim is to hold the single source of the truth for the definitions of the company’s data.
Application Internal Architecture
Describes the internal architecture of an application to reveal how the application functions. Elements appearing in the Internal Architecture Diagram are those necessary for correct operation of the application:- Internal components (modules, services, databases) enabling fulfilment of application "contracts"- Calls for services of other applications
Data ModelsInformation Architecture defines how data is stored, managed and used in an organisation. Data models are used for communicating data definitions, for scoping data requirements for projects and used for mapping applications showing where data is stored. It forms key component in a company’s data strategy.

• Progress to date � Mega Tool selected for EA modelling� EA Framework Developed� Process Modelling and IT Standards Defined� 1st Generation Website� Training Courses Developed� Built the Key Components of the EA Content
• EA required strong and committed sponsorship• EA requires alignment to company mission, objectives and values• Recognition that EA on its own will not deliver financial benefits, it
requires a business change framework to help realise those benefits• EA needs to be a business driven activity to achieve its potential benefits• Businesses need to understand potential benefits and take ownership for
building the content• Effective Stakeholder Management required at all stage of lifecycle to
