When the Enterprise is the size of a Western Nation Or Delivering a pan- government IT solution to benefit the whole of the UK Andy James : CTO Solidsoft Charles Young : Principal Consultant Solidsoft
When our critical life circumstances change, we may have to contact government many times, often to give the same information. An estimate of 35 types of changes of circumstance have been found and these give an average of 4.5 contacts per event. Birth, bereavement and change of address are not typical as they have an above average impact, but are exemplary nevertheless. For birth the number of contacts was found to be 15, affecting 11M people per year; for bereavement: 12 contacts, affecting 7M; and change of address: 9 contacts affecting 16M. Introduction
Varney Report • In November 2006, the Government published Transformational Government – Enabled by Technology • This set out an agenda of three key transformations: • services enabled by information technology must be designed around the citizen and business • there must be an increased culture of shared services to release efficiencies • there must be a broadening and deepening of government’s information technology professionalism • In the report Sir David Varney recommended an approach to put a citizen centric view on government services and simplify them for the citizen.
Tell Us Once • To meet the aspirations of the Varney Report the Tell Us Once Programme was born • By it’s very title the nature of the programme was for the Citizen to only have to tell government once for the whole of government to know • The focus became Change of Circumstance Events • In particular: Birth, Death and Change of Address
Today • Tell Us Once Pilot IT project is live in 15 councils about to be extended to 60 • Tell Us Once National System is in development • Today we are here to talk about the challenges of delivering an enterprise solution on this scale
The Challenges • Security, security, security! • Stakeholder Agreement! • Scalability • The timelines • Meeting the diverse requirements of over 400 councils • Providing a lasting architecture • Continue to deliver more services
The Aspiration • Great citizen experience • Re-use key Government resources • Use industry standard products and protocols • Provide a framework for future services • Rules driven approach to meet the ever changing landscape of government • Applicable across the whole of the UK
The Principles • The starting point is a face-to-face registration process • Citizen given option to provide further information • Citizen provides necessary information only once • Government departments and agencies ‘subscribe’ to the information they require • Finally information only retained for a short period
A few terms we may use • Service Provider – this is a local or central government endpoint that provides a service to the citizen. For example: DWP and Pensions • Citizen – the customer • Change of Circumstance – a major life change that requires a citizen to inform government about a change • Informer – the citizen who is providing the information
Stakeholders • DWP – both birth and death • HMRC – both birth and death • Identity and Passport Service – death • DVLA – death • UK Councils – death and birth
Stakeholder Issues • For death councils can receive information on over 10 different services • Large councils segment data across services • Small councils consolidate all services together • Some government departments want manual access some want integrated, pushed data
The Approach - IT • ‘Organic’ approach focused on the citizen • A limited prototype deployed across 15 councils • A number of additional ‘paper driven’ initiatives • Develop the National System based on the experience of the prototype • Controlled take-on of councils • 3 channels
The Prototype • Only delivering bereavement • Limited exposure • Prototyping approach and architectural concepts • ‘Live’ delivering real value • Life became far longer than expected
Services Supported • 25 different benefits / services supported • Including: • Pension • Attendance allowance • Housing benefit • Council Tax • Library services • Service Provider breakdown for death: • Councils – 10 services • DWP – 10 services • HMRC – 3 services • Passport Service – 1 service • DVLA - 1 service
The Results • Need for 3 channel approach • Process ideally breaks into two: • Capture Process • Distribution Process • Rules drive everything • UI • Capture • Distribution • Security concerns • Access – username password not enough • Data build up leading to IL4
Architectural Drive • Capture Data in as painless way for the citizen as possible, providing multi-channel, channel hopping and the Tell Us Once paradigm • Take data – tell citizen who we are going to pass it too • Process data and distribute in the service provider requested manner
The Capture Process Registered Data TUO (Capture) RegisteredData
The Distribution Process Submission Event Rules TUO (Distribution) Process Management Data Store Distribution
The High Level Architecture • SOA based • Microsoft stack • BizTalk powered ESB at the heart • Rules based UI • Rules based data capture • Rules based data distribution
Distribution • This is one of the key features of the system • 3 methods of data distribution: • Web Portal • ‘Push’ distribution via government gateway infrastructure • ‘Pull’ from TUO secure web service • Distribution granular to the level of service
Presentation UI • Abstracted from application • Supported by portal framework • Same style UI used for all channels • UI rules assist in collecting the data only once: • If informer lived with deceased then no need to take second address • Rules used to dynamically generate the page contents: • If deceased below pensionable age, for example, don’t ask if they had a pension! • Branded as DirectGov
Tell Us Once Because your time matters
Data Store Data Store IL4 IL3 • TUO Data Store • BTS Message Box • TUO Archive • TUO Audit • Registered Data Cache • TUO configuration • BTS configuration • BTS rules • TUO service directory • TUO MI Data Reference Data QAS
Rules for an EDA • Event-Driven • Not real-time! • Low throughput • Value is in distribution
Policies • System composes a large number of policies • 400+ councils – avg. of 10 services • 150+ additional service providers
Rule Categories • Flow Rules • Enabling • Authorisation • Service Bus • routing • governance • Intrusion detection • Data Distribution
Policy Management Framework • Common rule patterns across multiple event types • Versioned and audited policies • Traceability • Security • Automated composition and translation • Dynamic deployment
Security • Approached on many levels: • Data collected is only stored for a limited period: • Registered data for 28 days • Submitted data for 35 days – archived after that • Only the data a department is entitled to is provided • Personal data held at IL4
Security • Approached on many levels: • Main system accessed over GSI • Government Users require two factor authentication • Application has security built at its core
Scalability • Designed to scale from inception • Built using products designed for the enterprise • Partnering with infrastructure/hosting partner with track record of supporting this level of solution – ATOS Origin • Architecture segmented to deliver best performance to meet the differing requirements • Using existing scalable building blocks such as Government Gateway
The future • Delivery of first National Release Oct 2010 • Full integrated release April 2011 • Next Change of Circumstance – Address Change • System to be the basis for future cross government citizen projects
Summary • A different approach to delivering a national IT system • Focus has been primarily on the citizen • Pilot has had a huge success and great feedback from the users • National roll-out builds on that approach • Realistic vision, although timescales still tight • No attempt was made ‘To boil the ocean’
