Still Hard


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)


CTO Council – enabling shared services


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.


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.

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.


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”


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

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


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.

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)
