3. ESS EA: Origin and brief history
The origin of ESS EA is the ESS Vision 2020 released in May 2014:
"We will adopt enterprise architecture as a common reference framework"
"Enterprise architecture is a systematic language to describe the way our business wants to operate and how the various components fit together. It serves to translate our vision into implementation strategies and priorities in a systematic way. 3
Eurostat

4. EA basics Enterprise architecture aims at:
Creating an environment which can change and support business goals
Showing what are the business needs and where the organisation wants to be
Helping to remove silos, improves collaboration across an organisation, helps standardizing organisations
Ensuring that the technology is aligned to the business needs
EA discipline is based separation of concern and decoupling between 4 considered architectural layers: business, information, application, technology 4
Eurostat

5. EA basics: the different EA view points
Exploit business opportunities offered by technological evolution
Keep IT aligned on business needs in a changing environment 5

6. What Enterprise Architecture can provide to ESS Vision 2020
EA can ensure that projects
remain aligned with the ESS Vision 2020 objectives
will deliver reusable components where possible
EA can support portfolio managers
to monitor progress, detect gaps, integrate new results in implementing the ESS Vision 2020
to ensure that portfolio roadmap is well articulated, feasible and designed to achieve target

9. ESS EARF : Origin and brief history
The ESS EARF is the result of the collective and iterative work of the DIME/ITDG Task Force on ESS EA which ran from April 2014 till August 2015
ESS EA RF was adopted by the DIME and ITDG in February 2016
Since then it has been used to review ESS Vision and is maintained by the ESS EA Board bringing together EA experts from NL, IT, FR, PL, NO, UK & Eurostat 9

10. What is the ESS EA RF
A set of tools to be used by project/programme managers and ESS architects involved in the implementation of the ESS Vision 2020
The framework provides a common set of terms, methods, models and standards which form a starter set for the points that should be addressed in ESS Vision projects
These tools build on the conceptual and global frameworks for Officials Statistics (such as CSPA, GAMSO, …) and aim to fill the gap between concepts and implementation.

11. Overview of ESS EA RF Business Capability Model Principles
They represent what the ESS should/will be able to do
The realised by a combination of Processes, People & Organisation, Technology & Information, Methods, Standards and Framework
Principles
They provide norms (decision) and guidance (design) for project architects
They enshrine the ESS Vision 2020 values
The ESS capabilities model – the capabilities model identify and position the key capabilities required to implement Vision 2020 – capabilities are defined as practical ability to realise a business outcome by a combination of Processes, People, Organisation, Technology & Information, Methods, Standards and Framework. It serve as an anchor model for implementing the Vision
The ESS business process model – this is a statistical process flow model which provides a generic process flow supporting the statistical value chain visualising the impact of the Vision ideas like new data source, industrialisation, data pool
The ESS EA building blocks – identify the key functional building blocks supporting the implementation of the ESS Vision 2020
Principles– these are the principles to provide norms (decision) and guidance (design) for project architects
More detailed Business Function architectures to be developed stepwise – the Business Function architectures translate capabilities, processes, building blocks, as well as design principles and standards into practical Business Function use cases
Architecture building blocks
They define bundle of functionalities necessary to realise the ESS Vision 2020
These are the basis for deciding what to share and what are the implementation standards

14. Architecture Building Blocks (ABB)
The ESS EA RF identifies ABB which
Are homogeneous high-level functional components supporting the statistical value chain and the related capabilities
provide a basis for organizing technical infrastructure and services
Business capabilities
Architecture building blocks
Technical Architecture

15. The ESS ABBs
17 Building Blocks deemed necessary to realise the ESS Vision 2020 in NSIs
The basis for analysing the project IT developments and the reuse of existing components

16. ESS Statistical Production Reference Architecture
provides
A generic architecture linking the key ABBs
A functional view of the 3 main business functions of statistical production
A tentative list of business services and their link with GSBPM and the ABB;
A set of design principles
Scenarios for ESS deployment (opt-in / opt-out)
Refers to CPSA for statistical services identification, specification and design
