  • 5. Cross Government Shared Services
    • In the UK the ‘CIO Council’ was formed in January 2005 to align architectural initiatives across government. The alignment is expressed in, and enabled by, the Cross Government Enterprise Architecture (xGEA).
    • Shared Services are a key concern of the ‘CTO Council’, and the progress in this area can be seen in the maturity of the Government Gateway.
    • The current focus of the CIO Council is on shared corporate services across government ( http:// www.cio.gov.uk/shared_services/introduction )
  • 6. CTO Council – enabling shared services
  • 7. Shared Service Example - The UK Government Gateway
    • January 2001 – Government Gateway launched, heralding the start of the Government's online secure joined-up service delivery agenda. It provided multiple government departments and agencies with a common Authentication Engine, Registration and Enrolment Engine, Transaction Engine and Helpdesk Tools
    • July 2001 – Government Gateway wins its first major awards - Government Computing Innovation award and the Digital Britain award for joined-up government
    • October 2003 – Government Gateway Payment Engine launched
    • December 2005 – 100th live service enabled via the Government Gateway
    • May 2006 – The HMRC Self Assessment peak processed over 1 million submissions processed through the Government Gateway in a single month
    • November 2006 – The introduction of a 24 / 7 365 days a year service desk under a Managed Service Provider arrangement
    • January 2007 – 3 million people have submitted their Self Assessment Tax forms via the Government Gateway. Nearly 2 million people submitted their Self Assessment Tax forms via the Government Gateway in January 2007.
    • January 2009 – The Self Assessment submission peak surpasses all predictions, all processed within the expected timescales and with no service outage – 5.8m SA Tax submissions.
  • 8. Transformational Government Shared Services
    • The Cabinet Office document on Transformational Government Enabled by Technology , first published in November 2005, is the guide to a Shared Services vision for Government departments, including HMRC.
      • It includes Shared Services that are not Shared Solutions
      • It is focussed on services delivered to customers
    • Within HMRC, IMS has the key role of ensuring that the architecture is able to provide and support Shared Services.
  • 9. HMRC Context
  • 10. The Reference Architecture Framework CONTEXTUAL CONCEPTUAL LOGICAL PHYSICAL Business Information Information Systems Technology Infrastructure What is the business of the business ? What information does the Business require ? What IS functions are required ? What technical services are required ? How would the business be structured (ideally)? How would the information be related (ideally)? How would the functions be structured (ideally)? How are the boxes & wires structured (ideally) ? Which data storage and transfer mechanisms ? Which packages & bespoke software? Which h/w, systems s/w & network components What are the business drivers, goals and priorities? Which physical buildings, people etc… WHAT HOW WITH WHAT
  • 11. Traceability from Business Service to Technology

  • 16. We also Encourage Continuous Improvement Requirements Services Identify Funding for Shared Needs Design Authority for Shared Solutions Design Authority For Shared Portfolio Live Operations Projects Needs Capability
  • 17. Types of Sharing
    • The OASIS SOA-RM (  ) defines SOA as: “ Service Oriented Architecture (SOA) is a paradigm for organizing and utilizing distributed capabilities that may be under the control of different ownership domains. ”
    • We have an HMRC approach to sharing that is compatible with this.
  • 18. Issues of shared service provision
    • Funding
    • Project-defined solutions reflects project needs
    • Satisfying differing SLA’s
    • Accommodating change over time
    • Migrating from the existing “brown field”
  • 19. Types of Sharing
    • There are several ways to share:
      • Shared system
        • Copy a system into another instance
        • Share a single instance
        • Have a virtual instance on a shared platform
      • Shared Application Service (classic SOA)
        • Dynamically linked external services
        • Statically linked external services
      • Share supporting structures
        • Shared business support (e.g. shared printing)
        • Shared infrastructure support (e.g. shared storage)
      • Share Data
        • Master Data Management
        • Business Intelligence
      • Shared Resource
        • Common Contact Centres
  • 20. Types of Sharing within Shared Solutions ‘Shared Pattern’ ‘Shared Instance’ ‘Virtualised Infrastructure’ ‘Shared Data’ ‘SOA’ ‘Static Linking’ ‘Dynamic Linking’ ‘Cloned’ ‘Shared Solutions’
    • SOA in this diagram refers to applications where standard remote ‘call’ connection technologies, such as HTTP, are used to utilise external application services.
  • 21. Virtualised Infrastructure Platform Operating System Application Definition Instance Virtualisation of Platform, e.g. Mainframe context switching Virtualisation of Environment e.g. VMWare Virtualisation of Function e.g. Cloud Computing
  • 22. Shared Data Platform Operating System Application Definition Instance Shared Data through shared information pool Shared Data Through a Shared Instance Information
  • 23. Shared Instance Platform Operating System Application Definition Instance Shared Instance for all users Information can be shared or segregated by specific users or functions Information
  • 24. Shared Pattern Platform Operating System Application Definition Instance Development costs can be reduced by copying an existing pattern and creating ‘clones’. Platform Operating System Application Definition Instance
  • 25. Shared Oriented Applications Platform Operating System Application Definition Instance Reuse of existing functionality by remote invocation of another application Platform Operating System Application Definition Instance
  • 26. Transformational Government Shared Services
    • You have to measure success by the outcome.
    • In the Transformational Government Strategy there are 8 key areas within which Shared Services must be achieved:
      • Customer Service Centres
      • Human Resources, Finance and Corporate Services
      • Common Infrastructure
      • Data Sharing
      • Information Management
      • Information Assurance
      • Identity Management
      • Technology Standards and Architecture
  • 27. Historically, ‘HMRC’ Services have been Siloed with Little Sharing
    • HMRC was organised as two distinct departments: Inland Revenue and Customs & Excise, with separate systems and services.

  • 29. Shared Services within HMRC
    • We are still a long way from where we want to be, but we are making progress in most areas and have had some real successes. The lessons we have learnt are:
      • Aligning the entire business has been key, and this has been possible thanks to clear central government leadership.
      • Our suppliers have also contributed to this success, in supplying key technology and know how.
      • Involvement in the complete business cycle, has been vital including:
        • Identification of funding for shared needs (IMS Business Partners)
        • The Design Authority for Shared Portfolio (IMS Portfolios)
