Enterprise Architecture

Peter Connolly

Peter is head of Enterprise Architecture & the Design Authority.   The purpose of the Design Authority is to provide business focus and technology direction and assurance on our ICT technologies and platforms.    

The Design Authority takes an end-to-end view of the process cycle, providing assistance and assurance across the full design cycle.    At a technical level this includes the determination of standards, blueprints, and a test and assurance environment.   

The Authority also provides for data assurance.  This includes Data Security, Information Governance and semantic interoperability.   

The function takes an Enterprise Perspective on solutions looking at High Level Solution Designs (HLSD) that seek extended utility from our technology investments.   The Enterprise Architecture element of this division provides for team collaboration and cross functional sharing of artifacts. 

This is provided through a Confluence based collaboration platform.   

Previously, as project lead and chief architect for the HSE’s National E-Health Integrated Services Framework Project, Peter has driven the ICT interoperability agenda at the HSE.   This covered the standards based technical, business, and information aspects of the HSE’s ICT integrated services and systems architecture.

Peter has over 20 years experience in ICT spanning both the public and private sector.  He has spent the past 13 years in healthcare, including the roles of General Manager and IT Operations at Beaumont Hospital in Dublin Ireland. Prior to this his roles included senior management and technical positions with blue chip companies including AT&T, Lucent Technologies, Fore Systems and Marconi. His special areas of interest include business re-engineering and technology strategy, and he has lectured on both topics at university level.  

Peter holds a degree in Electronic Engineering and an MBA in Information Technology Management from the City University Business School, London.  


Enterprise Architecture 

Purpose

The key purpose of the Enterprise Architecture (EA) unit is to act as a Design Authority which facilitates the strategic development of the Office of the CIO (OoCIO) architecture, technology and operational capabilities in a standardised and aligned manner, conformant with both the Knowledge and Information Operating Model and eHealth Strategy.

The EA Function is currently in evolution and when mature will provide a design, support and validation service, based on International Standards and best practices. It will provide a consistent approach for defining, architecting and communicating the eHealth architectural viewpoints, technology components, and processes needed to deliver on our broad eHealth mandate. 

Areas of competency and support within the EA service include:

  • Business Architecture and Process Integration
  • Information Strategy and Architecture
  • Application Strategy and Architecture
  • Technology Strategy and Architecture
  • Information Governance and Security
  • Sourcing and Partnership Strategy

Key Benefits

  • The EA function will provide stakeholders with an increased understanding of our information technology (ICT) as it relates to the strategic eHealth planning and delivery process. It will provide a reference point and a consistent approach for defining and supporting the development of our national eHealth architecture. It will provide a means to leverage IT investments and avoid unnecessary duplication of infrastructure and major components
  • Provide architectural views that help communicate the complexity of large eHealth systems and facilitate the management of our extensive and complex eHealth environments
  • Provide Standardisation and focus on the strategic use of emerging technologies to better manage our information assets and consistently insert appropriate standards conformant technologies into our eHealth enterprise
  • Improve consistency, accuracy, timeliness, integrity, quality, availability, access and sharing of our OoCIO managed information assets across the enterprise
  • Support and link relevant business processes and provide a standardised business vocabulary
  • Ensure the sharing of reusable components and interoperability among programs, systems and applications
  • Lay the foundation for a national integrated Electronic Health Record (EHR)
