1 INTEROPERABILITY Electronic Transactions by Koussouris S., Lampathaki F., Askounis D.

2 What is Interoperability (Io)? IEEE glossary: the ability of two or more systems or components to exchange information and to use the information that has been exchanged ISO/IEC , Information Technology Vocabulary: the capability to communicate, execute programs, or transfer data among various functional units in a manner that requires the user to have little or no knowledge of the unique characteristics of those units European Commission / EIF v2.0: Interoperability is the ability of disparate and diverse organizations to interact towards mutually beneficial and agreed common goals, involving the sharing of information and knowledge between the organizations via the business processes they support, by means of the exchange of data between their respective information and communication technology (ICT) systems European Commission / Enterprise Interoperability Research Roadmap: Interoperability is a utility-like capability that enterprises can invoke on the fly in support of their business activities

3 Where is it a necessity? Systems ebusiness Systems (between different organisations) egovernment Systems Inter-Enterprise Systems Sub-Systems (Modules) of an Enterprise System Between enterprises or organisations regardless of IT infrastructures Data Between Data or Documents People Between.. People

4 Why is there a Chaos? Organisation A Organisation B Processes P1, P2, P3 P4, P5, P6 Processes Data D1, D2, D3 D4, D5, D6 Data Systems S1, S2, S3 S4, S5, S6 Systems

5 What is NOT Io Me Tax Office Processes VAT Payment Strike Processes Data FirstName, LastName Periodic Declaration Data Systems Credit Card Check Systems

6 What is Io Me Tax Office Processes Entering the Internet VAT Declaration Processes Data Username, Password DB with VAT Numbers Data Systems My Computer GSIS Server Systems

7 Right from the press Interoperability is viewed as the most important factor for information systems Financial Times, February 6, 2009

8 Can we achieve interoperability as an one-toone connection problem? Number of systems to be interconnected Number of connections to be established there should be another way Look for standards!

9 Interoperability Levels (EIF v2.0)

10 Enterprise Io Areas

11 The elements of Interoperability Organisational Interoperability (processes) Business Processes alignment, targeting collaboration between organisations, units, systems Proper setting and training of organisational units, for collaboration Semantic Interoperability (definitions) Common definition of terms, across organisations, units and systems Common definition and standardisation of exchanged information (e-invoice, e-vat, etc) Technical Interoperability (systems) Standards for systems architecture (how the interoperable system is designed) Standards for systems interconnection (communication, web services, service discovery) Standards for information storage and retrieval (formats)

12 Steps towards Organisational Io #1 Service Modelling #2 Definition of Roles within the Process Workflow #3 Service Homogenisation #6 Linking Services with Organisational Standards/Values #5 Development of One-Stop-Shop Service #4 Service Alignment (between different organisation) #7 Legislation Alignment #8 Rules for Information Flow/ Processing #9 Definition of Standards, Authentication Schemes, Communication Channels

13 Final and Intermediate Services Basic Service ID Issuing Entry in Municipal Records Final Service A Driving Licence (Category B) Intermediate Service A1 (level 1) Intermediate Service A2 (level 1) Health Certificate Intermediate Service A1.1 (level 2) Intermediate Service A2.1 (level 2) Fee Payment

14 Interoperability Application Areas A. Independent Services Interoperability is not an issue Their consumption by Services of B or C category (of this slide) is what matters B. Cross- Dependent Services Core Research Area for Interoperability C. Cross- Depended Services that include non electronic processes Cannot be made Interoperable without drastic change

15 egovernment Interoperability

16 Interoperability in egovernment: A key factor for the provision of true one-stop egovernment Services Enabling all the Public Administration stakeholders, enterprises and citizens Decomposing into organisational, semantic and technical aspects of systems and administrations

17 Interoperability in egovernment Parliament, Presidency Governmental Banks and G2C Services Other G2G Services Organisations Intermediaries Citizens Governments Ministries Prefectures Districts G2B Services International Organisations Municipalities Enterprises G2G Services

18 Io Ingredients for Issuing an ID Card* Is there a process for quering=retrieving a Birth Certification between the Municipality and the Police Department? Are the data requested the same in the Birth Certificate and in the ID Issuing form? Are the IT systems ready to talk? Are there the same security/authentication mechanisms? * In Greece, issuing an ID Card requires the retrieval of a Birth Certificate for the Municipality a person was born Is data stored as needed?

19 Data and Information Modelling (Today) Syntactic Data Representation e.g. Address fields Semantic Data Representation e.g the same information can have synonyms and different meaning Semantic Data Mapping with Lists e.g. Codelists vs. Descriptions (ISO lists, NACE codes, etc )

20 Data and Information Modelling (Tomorrow) ü Standard Documents based on XML ü XML Schemas for Structuring ü Common, Reusable Data Units with common semantics ü Semantic Mapping with commonly agreed lists

21 The size of the problem in Greece Organisational Aspect 18 ministries, 13 prefectures, 52 districts, 1024 municipalities, 691 Public Organisations, 25 Banks 5,500 Governmental Points of Service > 2,000 non-interoperable Service Types from Government to Citizens and Businesses > 10,000 Document Types exchanged between Administrations and the public Systems Aspect 200 Governmental Internet Portals 1000 Municipal Internet Portals 2,500 Public Administration Back Office Systems Non-Governmental Stakeholders aspect 1,000 IT and services companies 750,000 Enterprises, SME s and VSE s 11,000,000 Citizens 18,000,000 Tourists every year > 20,000,000 service requests per year (mostly non-electronic, mostly non-interoperable)

22 What does this mean for the Public Administration Interoperability should be established between: All Public Administrations All Public Sector Companies All Private Enterprises All citizens And preferably between GR and other countries

23 The 3 egov-interoperability Rules #1 Target organisational and semantic aspects first: technical standards exist already Follow the service: build your guidelines around the actual, most common services #2 #3 Enable all stakeholders (public administrations) and allow for constant evolution and change

24 Key Findings after many attempts (1/2) To truly enable interoperability across government, a bottom-up approach starting with technology must be avoided. Articulating organizational and semantic interoperability issues deserves more priority and effort than the technical interoperability layer that has already mechanisms and standards in place. The adoption of a service-oriented approach is a crucial factor for implementing onestop interoperable egovernment. The diffusion of needed basic infrastructure, such as electronic ID s, base registries and fundamental governmental web services has not reached the minimum needed threshold.

25 Key Findings after many attempts (2/2) A clearly defined NIF Governance Model needs to be envisioned and put in place by determining observance mechanisms, measuring effectiveness and stimulating growth of successful projects. No matter how well prepared a government is, it is illusionary to believe that it can achieve interoperability at once in one big step. Although interoperability is well-sought for at a national context, cross-country collaboration issues remain an important barrier.

26 The Way Forward (1/2) Designing and implementing appropriate infrastructures in the form of Base Registries accompanying the NIF specifications Supporting standardized transformation and re-engineering efforts that fully integrate front- and back-office systems Exploiting Web 2.0 tools in egovernment Strengthening organizational and semantic interoperability aspects

27 The Way Forward (2/2) Building a Science Base for Interoperability Creating interoperability value assessment models Applying best practices from other domains, i.e. ebusiness, ebanking Coordinating efforts within the egovernment interoperability domain through Excellence Centres and appropriate initiatives

28 Expected Impact (1/3) For Public Administrations Openess of organisation Common Visibility and Presence over the Web Less Bureaucracy Transparency Quality of Service Utilisation of High Efficiency Systems/Channels Collaboration between other organisation Economies of Scale by re-utilisation of IT resources (hardware/software)

29 Expected Impact (2/3) For People/Enterprises Quality of Service Increase Response Times Information Access through multiple channels Ease of Searching and Discovering Information Improvement of Trust feeling

30 Expected Impact (3/3) IT Companies Products and Applications responding to a priori commonly agreed specifications Provision of ready made COTS (Components of the Shelf) for standardising processes and documents Faster response to Public Adminstration calls for implementation of systems Minimisation of Customised Solutions and multiple, parallel production lines

31 Conclusions Interoperability reaches all governmental organizations at national and international level and constitutes a thriving research domain from all aspects scientific, entrepreneurial, societal and political. Research on interoperability in digital public services provision will have, in the next years, to face the multi-disciplinary nature that interoperability problems present. Interoperability Standards for e-government is a dynamic space, with many directives, initiatives and standards evolving at the same time. Administrations and industry worldwide are trying hard to cope with the developments. Interoperability in digital public services cannot be achieved without process re-organisation, legal system re-structuring and data rework.

32 It s not like Parkour (run, jump, land)

33 it is more like crossing the desert in a Paris-Dakar rally So be prepared and have plenty of resources!

34 Interoperability Frameworks

35 What is an IF (Interoperability Framework)? set of recommendations which specify how Administrations, Businesses and Citizens communicate with each Wikipedia Defines rules, sets specifications and standards for the development and operation of IT systems that allow: Cross-Interoperability amongst Organisations Integrated systems Secure Communication
