ELAP 3.0.0 Online Documentation

This is an ongoing work. This will be published once the maintenance task are finished. 

Introduction

The ELAP was created out of a carefully selected set of sources deemed necessary to help achieve the goals of ELAP, and more specifically the goals of the interoperability programs within public institutions in Europe. Architecture principles provide a highly abstract view of the interoperability requirements, which are implemented by its interoperability specifications. Besides the EIF principles – which are considered architecture principles in ELAP – other sources are also considered and included. The principles are qualified based on their applicability (i.e. the usefulness of providing guidance when realising SBBs) and on their legal or regulatory basis by aiding architects involved in IT programs to ensure full compliance with the European regulatory framework.

In the table of contents below there can be found the 55 different Architecture principles mapped by ELAP, along with their definition (composed of 'Statement', 'Rationale', and 'Implications'), principle source, source URL, scope, category and PURI.  

Statement: Accessibility ensures that data, services, and solutions from public administrations are available and usable by all citizens, regardless of their capabilities, background, or disabilities, through standardised mechanisms.

Rationale: Implementing the principle of Accessibility when providing public services is crucial for promoting inclusivity and ensuring that all citizens can benefit from public services and data. Service accessibility ensures that public services are designed to be perceivable, operable, understandable, and robust, catering to the diverse needs of all citizens, including those with disabilities. By adhering to accessibility principles, public administrations can enhance user experience, foster trust, and ensure compliance with legal and regulatory requirements. Accessibility also supports social equity by providing equal opportunities for all individuals to access information and services, thereby reducing digital divides and fostering a more inclusive society.

Implications: To effectively implement Accessibility, organisations must adopt standardised mechanisms. Public sector bodies must take necessary measures to make their electronic services perceivable, operable, understandable, and robust. This includes designing, constructing, maintaining, and updating digital services with accessibility principles and techniques in mind, ensuring that all citizens, regardless of their digital capabilities, can access and benefit from these services. Additionally, organisations should implement regular accessibility audits and user testing to identify and address any barriers. Training and awareness programs for staff are essential to embed accessibility considerations into the organisational culture. Legal and regulatory frameworks should be established and enforced to ensure compliance with accessibility standards, promoting a consistent and inclusive approach across all public services.

Statement: Digital public services should be developed and provided to enable stakeholders to hold public administrations accountable by ensuring that their actions, decisions, and outcomes are open to scrutiny and evaluation. 

Rationale: Accountability is a fundamental aspect of good governance, requiring public administrations to be held accountable for their actions and decisions. It encompasses various dimensions, including transparency, liability, controllability, responsibility, and responsiveness. By integrating accountability into digital public services, administrations can demonstrate their commitment to ethical practices, foster trust, and enhance public engagement. Transparency is tightly related to accountability as it plays a crucial role in accountability by making information about actions and decisions accessible and understandable, thus allowing stakeholders to evaluate and hold administrations responsible. Auditability further strengthens accountability by enabling the systematic and independent examination of actions and decisions, ensuring compliance with established standards and promoting a culture of responsibility and responsiveness. 

Implications: To effectively implement Accountability, public administrations must adopt practices that ensure their actions and decisions are documented, accessible, auditable, and subject to evaluation. 
This includes ensuring that all actions, decisions, and their rationales are thoroughly documented and made accessible to stakeholders through digital platforms. Establishing mechanisms for continuous monitoring, evaluation, and independent auditing of actions and decisions allows stakeholders to provide feedback and hold administrations accountable. Leveraging transparency provides clear and understandable information about how decisions are made, data is used, and actions are taken, thus supporting accountability. Promoting ethical behavior by making the decision-making process open to scrutiny and audit encourages administrations to act responsibly and ethically. Fostering a culture of openness and engagement where stakeholders are encouraged to participate in the evaluation and audit processes enhances their trust and involvement.

Statement: Where possible, public administrations should seek to streamline and simplify their administrative processes by improving them or eliminating any that do not provide public value.

Rationale: Administrative simplification means, where possible, streamlining and simplifying administrative processes by improving them or eliminating anything that does not provide public value. Administrative simplification can help businesses and citizens to reduce the administrative burden of complying with EU legislation or national obligations.

Digitisation of public services should take place in accordance with the following concepts:

• digital-by-default, whenever appropriate, so that there is at least one digital channel available for accessing and using a given European public service;

• digital-first which means that priority is given to using public services via digital channels while applying the multi-channel delivery concept and the no-wrong-door policy, i.e. physical and digital channels co-exist.

Implications: Simplify processes and use digital channels whenever appropriate for the delivery of European public services, to respond promptly and with high quality to users’ requests and reduce the administrative burden on public administrations, businesses and citizens.

Statement: Digital public services ensure Auditability by enabling a traceable record of all activities within the system, allowing for systematic examination and verification by stakeholders.

Rationale: Auditability is a critical component of good governance, ensuring that all actions and decisions within digital public services can be independently verified and scrutinised. It supports transparency and accountability by providing a clear, traceable record of activities, which is essential for evaluating compliance, detecting anomalies, and ensuring ethical practices. By making audit trails available, public administrations can demonstrate their commitment to openness, integrity, and continuous improvement. Auditability enhances trust among stakeholders by ensuring that all processes are transparent and accountable, thereby fostering a culture of responsibility and responsiveness.

Implications: To effectively implement Auditability, public administrations must adopt technical and procedural measures that ensure all activities within digital public services are traceable and verifiable. Technically, auditability requires the implementation of robust digital systems that capture and store data securely while making it accessible for audits and public scrutiny. These systems should include comprehensive audit trails that record every action and decision within the system, ensuring that a trace can be done on an entity’s activities. Advanced data analytics tools can be employed to identify patterns and anomalies, further supporting the audit process. Additionally, ensuring compliance with government regulations and policies is crucial for maintaining the integrity and reliability of audit trails. Additionally, public administrations should establish mechanisms for continuous monitoring and independent auditing of actions and decisions, allowing stakeholders to provide feedback and hold administrations accountable.

Statement: Code of ethics compliance refers to the expression of important values and standards that are also to be found in the law, but not only aspects related to legally-binding issues. 

Rationale: A code of ethics is a written set of expectations that an organization has for its employees to conduct business in an honest manner. Ethics are values and principles that govern behaviour or conduct.

Apart from legislation, the European foundational text "Treaty on the Functioning of the European Union" sets up the different terms and relevant aspects for the proper function of the European Union.

All public services provided by public administrations under the European Union need to be alifned and compliant with organisations code of ethics, which should be aligned with national and european values. 

Implications: All initiatives and services must be aligned and compliant with a code of ethics.  (Ad-hoc for the organisational, local, regional, national or at European Level).

Statement: Composability ensures that solutions are divided into modular building blocks that can be aggregated and orchestrated, simplifying their selection, increasing reuse potential, and enabling interchangeability and flexibility.

Rationale: Implementing the principle of Composability in digital public services and solutions is crucial for reducing complexity and enhancing flexibility. By dividing a solution into modular building blocks, each with clear boundaries and specific capabilities, organisations can address smaller, more manageable problems. This approach simplifies the selection process, as building blocks can be easily identified and chosen based on their defined scope. Composability also increases the potential for reuse, as well-defined building blocks can be repurposed across different solutions. Additionally, it allows for flexibility, as building blocks can be substituted or reconfigured without affecting the overall system, enabling continuous improvement and adaptation to changing requirements.

Implications: To effectively implement Composability, organisations must adopt a modular approach to design and development, ensuring that each building block has a well-defined scope and set of responsibilities. Business processes should include clear guidelines for defining, documenting, and selecting building blocks. Technically, solutions must support modularity and interoperability, with components that can be easily integrated, replaced, or reconfigured. Continuous monitoring and evaluation are necessary to ensure that the composability principle is maintained throughout the lifecycle of the solution. Additionally, fostering a culture of innovation and collaboration is essential to encourage the development and reuse of modular building blocks. Training and capacity-building initiatives should be implemented to ensure that all stakeholders understand and can effectively apply the principle of composability.

Statement: Conformance chain ensures that the analysis, design, and implementation of Digital Public Services adhere to selected reference architectures and specified requirements, achieving deterministic behaviour and interoperability

Rationale: Implementing the principle of Conformance chain in the lifecycle of digital public services and solutions is crucial for ensuring consistency, reliability, and interoperability across different levels (e.g., EU, National). By adhering to reference architectures, such as the European Interoperability Reference Architecture (EIRA), organisations can ensure that their solutions align with established standards and best practices. The alignment facilitates the interoperability of components and services, reducing complexity and enhancing the overall quality of the DPS. Conformance also ensures that solutions meet specific requirements and specifications, such as those for eDelivery Access Points, thereby promoting a cohesive and efficient digital ecosystem. Ultimately, conformance supports the creation of robust, scalable, and compliant public services.

Implications: To effectively implement Conformance chain, organisations must adopt and adhere to selected reference architectures and standards. Business processes should include rigorous conformance assessments and validation steps (e.g. through the Interoperability Test Bed) to ensure that the analysis, design, and implementation of DPS align with the chosen reference architectures and specifications. Technically, solutions must be designed to support interoperability and compliance with established standards, including the use of specific building blocks and components. Continuous monitoring and evaluation are necessary to maintain conformance throughout the lifecycle of the solution. Additionally, fostering a culture of adherence to standards and best practices is essential to ensure that all stakeholders understand and commit to the principle of conformance.

Statement: Public administrations must ensure that digital public services are aligned with public policy goals, designed to address societal needs, and monitored for efficiency and effectiveness in their implementation and delivery.

Rationale: Digital public services are a key instrument for implementing public policies that address real and relevant societal needs. To ensure their success, it is essential that these services are designed, implemented, and monitored in alignment with public policy goals, maximising their efficiency and effectiveness in meeting societal demands.

Public administrations have a dual responsibility: firstly, to evaluate and ensure that resources dedicated to the implementation of digital public services are proportionate to the societal needs they address and the value they provide; secondly, to continuously track and control these efforts to ensure alignment with policy objectives without introducing inefficiencies or unnecessary expenditures.

By combining the assurance of alignment with public policies and ongoing control mechanisms, public administrations can ensure that digital public services deliver tangible benefits, remain sustainable, and uphold the principles of accountability, efficiency, and effectiveness. This principle emphasises the need for strategic coherence, resource optimisation, and consistent evaluation to achieve impactful public policy outcomes.

Implications: To ensure alignment with public policy objectives, digital public services must clearly address societal needs and be prioritised based on their value and impact. Resources should be allocated efficiently, focusing on services that provide tangible benefits while avoiding unnecessary expenditures. Public administrations must establish systems to monitor and evaluate the progress, efficiency, and outcomes of these services, ensuring they remain aligned with policy goals. Collaboration across government bodies is essential to maintain coherence, with clear accountability for achieving results. Additionally, digital services should be designed to be adaptable and interoperable, enabling seamless collaboration and flexibility to respond to evolving needs. Finally, active engagement with citizens and businesses is vital to ensure services are relevant and effective in addressing real societal challenges.

Statement: Public services are transformed into digital public services, while ensuring that no one is left behind. 

Rationale: Making public services digital makes them more accessible, reduces administrative burdens and time and allows faster responses to individuals and organisations. The European Commission has set out a strategy for the digital transformation of its own services, with a preference for digital communication channels. This is also reflected in the EIRA's focus on digital public services, which nonetheless foresees alternative service delivery models besides the primary digital channels.

Implications: Laws and regulations are adapted to remove barriers to digital transformation, enabling the provision of digital services. Public administrations aim to transform existing public services into digital formats, ensuring they can be easily found and accessed by users on their websites. Additionally, digital public services focused on government-to-business interactions are made accessible through automated system interfaces, such as APIs.

Statement: A full life cycle cost of ownership (including retirement costs) should form part of the business case.

Rationale: Public administrations are the first link in the chain and need to set an example for society and businesses by managing the entire life cycle of technology products. Therefore, when planning and designing public services, this aspect needs to be included from design and implementation to retirement. Such care for the full ICT life cycle comes at a critical stage for sustainable development, amplified by the excess use of resources (economic, natural, etc.). Considering this, public administrations need to establish and use relevant policies that help ensure and control sustainability at all levels. 

Implications: When implementing and retiring elements related to the provision of digital public services, public administrations shall include and create policies that ensure the lifecycle of infrastructures, applications services and equipment is considered and extended to ensure the minimum waste in terms of sustainability.

An example regarding this last topic is, for instance, the application of policies to ensure that no additional costs (economic, social and environmental) rise when renewing the computer fleet.

Statement: A Level playing field ensures that all participants have equal opportunities to collaborate and participate eliminating monopolistic barriers to entry across all layers of digital public services creation.

Rationale: Implementing a Level playing field in solution architecture is essential for fostering a fair and competitive environment. It prevents monopolistic situations where a few entities dominate due to their control over vast amounts of resources, including data, infrastructure, and digital services. By ensuring that new entrants face no insurmountable barriers, it encourages innovation and improves the overall quality of services. This principle is pivotal for creating a fair digital public services ecosystem, where collaboration and participation are based on service excellence rather than resource control, ultimately benefiting consumers and promoting a healthy market. For example, public administrations at different levels (State, Regions, Local) should be able to collaborate and join efforts in new services without being limited by their varying levels of resources. Another example, when procuring any kind of digital public service solutions, public administrations should provide as much information as possible to all participants, ensuring that all possible candidates have access to the same information, so all play by the same set of rules resulting in formal equality of opportunity. 

Implications: To establish a Level playing field, organisations must adopt policies and practices that promote accessibility and interoperability across all layers of digital public services. Business processes should be designed to ensure that resources are shared fairly and transparently, with clear guidelines to prevent monopolistic practices. Technically, solutions must support open standards and APIs to facilitate resource exchange and ensure that governance frameworks are in place to manage access and usage equitably. Additionally, technical agreements and mechanisms must address the needs and expectations for infrastructure, ensuring that infrastructure resources are shared, reused, and utilised effectively, without implying unfair situations between participants that could extend to the service's end users. Additionally, continuous monitoring and enforcement mechanisms are necessary to maintain a fair competitive landscape and address any emerging monopolistic tendencies. Collaboration and reuse should be encouraged to ensure that all participants can contribute effectively, regardless of their resource levels.

Statement: European digital public services are multilingual.

Rationale: European public services can potentially be used by anyone in any Member State. So Multilingualism needs to be carefully considered when designing them. Citizens across Europe often have problems accessing and using digital public services if these are not available in the languages they speak.

Implications: Multilingualism is taken into account at all levels in the design of European digital public services, e.g. also in documentation and systems interfaces. 
A balance needs to be found between the expectations of citizens and businesses to be served in their own language(s) or their preferred language(s) and the ability of Member States’ public administrations to offer services in all official EU languages.
A suitable balance could be that European public services are available in the languages of the expected end-users, i.e. the number of languages is decided on the basis of users’ needs, such as the level to which the service is critical for the implementation of the digital single market or national policies, or the size of the relevant audience.

Statement: Citizens and businesses provide data to public administrations only once.

Rationale: Requesting the data multiple times leads to an unnecessary administrative burden for citizens and businesses. It also leads to multiple administrations of the same data, with a high risk of inconsistency and low data quality. It is essential that the data that public administrations use is of good quality, in order to prevent errors and delays in processes and provide high-quality services. 

Implications: There is a central metadata administration of all the datasets that public administration bodies have available for reuse.
Public administration bodies first determine whether specific data elements are available for reuse before they decide to collect them.
Data that can be reused from other public administrations are not requested from citizens or businesses but simply referred to.

Statement: Existing digital systems are reused, before deciding upon buying or even building them.

Rationale: Reusing existing systems, services, and solutions can lead to substantial cost savings, as the expenses associated with developing and maintaining new systems are often much higher than anticipated. This principle ensures that public administrations make efficient use of resources by leveraging existing investments and avoiding unnecessary duplication. Additionally, reusing proven solutions can enhance the reliability and interoperability of public services, as these systems have already been tested and validated in real-world scenarios. By prioritising reuse, public administrations can focus on optimising and integrating existing solutions to meet their needs, fostering innovation and improving service delivery without incurring the high costs and risks associated with building new systems from scratch.

Implications: Implementing the principle of "Reuse, before buy, before build" requires both business and technical considerations. Public bodies and administrations must conduct thorough assessments of existing systems, services, and solutions to determine their suitability for reuse. This involves evaluating the functionality, scalability, and interoperability of these systems to ensure they can meet current and future requirements. When existing solutions are not sufficient, the next step is to consider purchasing commercial off-the-shelf (COTS) solutions that can be customised to fit specific needs. Building new systems should only be considered as a last resort when no existing solutions can fulfil essential requirements.

From a technical perspective, public administrations must establish robust frameworks for evaluating and integrating existing systems. This includes adopting open standards and protocols to ensure interoperability, implementing secure data management practices, and maintaining comprehensive documentation to facilitate the reuse of systems. Additionally, public bodies should promote a culture of collaboration and knowledge sharing, encouraging the reuse of solutions across different departments and agencies. By following these guidelines, public administrations can achieve cost-effective, sustainable, and efficient service delivery, while minimising the risks and costs associated with developing new systems.

Statement: Scalability is the measure of a system’s ability to increase or decrease in performance and cost in response to changes in application and system processing demands.

Rationale: Scalability is crucial for ensuring that systems can efficiently handle growth in demand, whether due to increased traffic, data volume, or user activity. It supports business continuity enabling failure recovery and adaptation to unforeseen changes. Furthermore scalability ensures regulation compliance in cases where resiliency and the gracefully handling of increased demand are key aspects in the delivery of digital public services.

Implications: Achieving Scalability involves leveraging modern and flexible infrastructure to accommodate fluctuations in user needs or system processing demands, ensuring continuity and efficiency even under growing workloads or during periods of high demand. Scalable public services should also be designed to enable reuse and interoperability, allowing for the efficient adaptation and expansion of solutions across borders and contexts.

Statement: Security by Design refers to the principle that security should be integrated into the design and development of IT systems and digital public services from the outset. This approach ensures that security measures are an inherent part of the system, rather than being added as an afterthought.

Rationale: Security by design encompasses the protection of valuable assets by embedding security protocols throughout the entire lifecycle of IT systems and digital public services. This principle ensures that data and technology are safeguarded within organisational boundaries, considering asset ownership. By securing access to data assets and controlling their dissemination, organisations can protect sensitive information and maintain trust. This proactive approach minimises vulnerabilities, reduces long-term costs, and ensures compliance with regulatory requirements. Ultimately, Security by Design fosters a robust security posture that adapts to evolving threats and enhances overall system resilience.

Implications: Implementing Security by design implies a comprehensive and systematic approach to security across all stages of creating digital public services, from design to implementation. This approach has holistic implications across multiple layers: (I) Legal Level: Ensures compliance with data protection regulations and legal standards; (II) Organizational Level: Promotes a culture of security awareness and responsibility among all stakeholders; (III) Technical Level: Involves integrating security features such as encryption, access controls, and real-time monitoring into the system architecture. It also supports automation and data-driven decision-making to enhance security measures.

Statement: Separation of concerns ensures that each building block of a solution or service has a specific scope in terms of concern and capabilities, avoiding the replication of functionalities across different components.

Rationale: Implementing the principle of Separation of concerns in solutions and service development and provision is crucial for enhancing clarity, maintainability, and scalability. By clearly defining the scope and responsibilities of each component, this principle helps to reduce complexity and improve the manageability of the system. It ensures that each building block can be developed, tested, and maintained independently, leading to more modular and flexible solutions. This approach also facilitates better collaboration among teams, as responsibilities and interfaces are clearly defined, reducing the risk of overlapping functionalities and dependencies.

Implications: To effectively implement Separation of concerns, organisations must adopt a modular approach to design and development, ensuring that each component has a well-defined scope and set of responsibilities. Business processes should include clear guidelines for defining and documenting the boundaries and interfaces of each building block. Technically, solutions must be designed to support modularity and interoperability, with components that can be easily integrated and replaced without affecting the overall system. Continuous monitoring and evaluation are necessary to ensure that the separation of concerns is maintained throughout the lifecycle of the solution. Additionally, fostering a culture of collaboration and communication is essential to ensure that all stakeholders understand and adhere to the principle.

Statement: Service orientation is a way of thinking in terms of services and service-based development and the outcomes of services.

Rationale: Being user-centred or remaining "user-led," is possible with a service-oriented strategy. It entails offering services that employ the best technological solutions to provide better results. By making this change, the organization will put user demands and goals at the centre of its vision, culture, and operations. After then, make sure that everyone supports it and owns it so that decisions and technology are driven by user demands.

A service-oriented strategy entails developing an IT platform made up of numerous systems, each one tailored to carry out particular tasks. You can change one aspect of a system's functionality with a tech stack made up of separate components without changing the operation of the entire system. Certain components can be digitalized more quickly because of this function fragmentation, which also offers a distribution strategy that allows for independently distributed functions. Communication with external programs is also made possible by separate systems where each software tool is designed to carry out a specific task using a well-defined interface.

There are a variety of technologies that can be applied to this service orientation approach such as SOAP, REST API and GraphQL. 

Implications: At the organisational level, public administrations need to establish the proper agreements that allow collaboration and common mechanisms to provide relevant information through the desired Service Oriented Architecture.

At the technical level, the organisations in charge of implementing and delivery of digital public services will need to determine which is the best approach to fit their needs. There are different approaches such as SAP, RESTApi or GraphQL, taking into account the relevant aspects of the services, the organisation responsible for the service should select the more sustainable and efficient way of implementing the SOA approach.

Statement: The selected solution/approach is the best possible aligned with the requirements.

Rationale: Ensuring the chosen solution meets the specific requirements, and therefore the needs and expectations of the public services is crucial to ensure efficient and effective service provision. By carefully selecting the appropriate solution, organisations can achieve optimal performance, cost-efficiency, and alignment with their strategic goals. This principle helps avoid mismatches between requirements and solutions, which can lead to inefficiencies, increased costs, and project failures. Ensuring a proper fit enhances the overall effectiveness and success of the solution.

Implications: To effectively implement the Solution fit principle, organisations must conduct thorough requirement analysis and ensure that the selected solution addresses all relevant levels—organisational, semantic, and technical. Business processes should include rigorous evaluation and selection criteria to match solutions with requirements accurately. Technically, solutions must be assessed for compatibility, scalability, and alignment with existing systems and standards. Continuous monitoring and evaluation are necessary to ensure that the solution remains fit for purpose as requirements evolve.

Statement: Sovereignty ensures that digital infrastructures, products, and services safeguard European security, strategic assets, and interests while respecting European values and requirements.

Rationale: European Institutions and Administrations represent citizens and businesses, ensuring the holistic development of European society. By preventing dependency on external stakeholders, this principle helps avoid monopolies and vendor lock-in, which can lead to inefficient solutions and vulnerability to external influences. Sovereignty encompasses vendor lock-in, data sovereignty, and platform sovereignty, ensuring that digital solutions are aligned with European strategic interests and values. This principle promotes the development of independent, secure, and sustainable digital infrastructures, enhancing trust and resilience in public services. 

Implications: Organisations must adopt technical alternatives that promote cost-effective, sustainable, independent, and secure solutions. This involves conducting prior assessments of the suitability of these alternatives, considering each area of implementation, and taking into account relevant legal frameworks. From a business perspective, it is essential to establish policies that support digital sovereignty, including procurement practices that favour local or European providers and the development of in-house capabilities. Technically, systems must be designed to ensure data sovereignty, with robust data management practices and secure infrastructures that prevent unauthorised access and control by external entities. Continuous monitoring and evaluation are necessary to maintain compliance with sovereignty requirements and to adapt to evolving threats and challenges.

Statement: The Subsidiarity principle requires decisions to be taken as closely as possible to the citizen, ensuring that actions are taken at the most effective level, whether local, regional, or national.

Rationale: Implementing the Subsidiarity principle in public administrations solutions ensures that decisions are made at the level closest to the citizens, enhancing responsiveness and accountability. This principle helps to safeguard the ability of Member States to take action and make decisions that best address their specific needs and contexts. By promoting localised decision-making, subsidiarity fosters greater engagement and trust among citizens, leading to more effective and tailored public services.

Implications: To effectively implement Subsidiarity, organisations must establish governance structures that empower local and regional authorities to make decisions. Business processes should be designed to facilitate localised decision-making, including mechanisms for citizen engagement and feedback. Technically, solutions must support decentralised data management and interoperability to ensure that local systems can operate independently while still integrating with broader frameworks. Continuous monitoring and evaluation are necessary to ensure that decisions made at the local level are effective and aligned with overall objectives.

Statement: Transparency ensures that all phases and aspects of digital public services and solutions, including data, decisions, and processes, are open, accessible, and understandable to all stakeholders.

Rationale: Transparency in digital public services and solutions is crucial for fostering trust, accountability, and engagement among citizens and stakeholders. Transparency in digital public services ensures that data is easily accessible, understandable, and usable, promoting better decision-making and enhancing public trust. By making information about how data is collected, processed, and used openly available, organisations can demonstrate their commitment to ethical practices and accountability. Transparency in decision-making processes allows stakeholders to understand the rationale behind decisions, fostering a sense of inclusion and participation. Overall, transparency supports the creation of a more open, responsive, and trustworthy public sector, driving innovation and improving service delivery.

Implications: To effectively implement Transparency, organisations must adopt practices that ensure openness and accessibility of information across all phases of digital public services. Business processes should include clear guidelines for data transparency, ensuring that data and metadata are available through standardised mechanisms and maintained for long-term availability. Decision-making processes should be documented and made accessible to stakeholders, providing insights into the rationale and criteria used. Technically, solutions must support real-time data access, user-friendly interfaces, and robust security measures to protect sensitive information while ensuring transparency. Continuous monitoring and evaluation are necessary to maintain transparency and address any emerging issues. Legal and regulatory frameworks should be established/referenced to support and enforce transparency measures, ensuring compliance and promoting a high level of public sector integrity.

Statement: The organisation behind digital public services and the data manged need to incorporate the relevant mechanisms to ensure overall trustworthiness.

Rationale: Trust entails citizens' reliance on trustworthy and verifiable digital government applications and services, which fully conform to high-security standards and respond to user needs. Fundamental rights and security should be integrated into all policies with a digital dimension. To foster trust in digital interactions with the public sector, suitable regulatory frameworks that ensure transparency, predictability, security-by-design and, where necessary, reinforcement or adjustment of existing provisions must be provided.

Implications: The principle has a horizontal approach, where it affects the adoption of legal measures, organisational mechanisms, and technical means to ensure services are part of a network of trustworthiness interactions.

At the legal level, relevant and binding legislation needs to be put in place to ensure legal interoperability and guarantee that trust is the base of data interactions (exchange, processing, etc, amongst digital public services).

At the technical level, mechanisms, tools, and standards should be part of the certification of processes, ensuring that data exchanges between stakeholders are saved with built-in integrity and trust provisions.

Statement: Uncertainty management acknowledges the degree of confidence in decisions made during the analysis and design of Digital Public Services, arising from imperfect, unknown, or partial information.

Rationale: Uncertainty management is crucial for recognising and managing the inherent limitations in knowledge and information. By acknowledging uncertainty, organisations can make more informed decisions, anticipate potential risks, and develop strategies to mitigate them. This principle helps improve the quality of problem descriptions and solutions by encouraging thorough analysis and consideration of various possible outcomes. Addressing uncertainty enhances the robustness and adaptability of Digital Public Services, ensuring they can effectively operate in partially observable or stochastic environments.

Implications: Organisations must adopt practices that recognise and address the limitations in information and knowledge. Business processes should include thorough risk assessments and scenario planning to anticipate and mitigate potential uncertainties. Technically, solutions must be designed to be flexible and adaptable, capable of handling incomplete or evolving information. Continuous monitoring and feedback mechanisms are essential to update and refine solutions as new information becomes available.

Statement: The Use of standards for the design and implementation of digital public services is key to ensure robust, efficient and interoperable solutions, fostering collaboration across organisations and quality in the delivery.

Rationale: Implementing the principle of using standards in the design and implementation of solutions is crucial for ensuring consistency, reliability, and interoperability across digital public services. Standards provide clear benchmarks and guidelines that help streamline development processes, reduce complexity, and enhance the quality of services. By adhering to established standards, organisations can ensure that their solutions are interoperable with other systems or services, facilitating seamless data exchange and integration. This approach also promotes transparency and accountability, as standards are often developed through consensus and reflect best practices. The Interoperable Europe Act underscores the importance of using harmonised standards to support the development of interoperable public services, contributing to government efficiency and reducing administrative burdens and costs for citizens and businesses. Compliance with these standards, while generally voluntary, provides a presumption of conformity with essential requirements, enhancing trust and reliability. Ultimately, the use of standards supports the creation of robust, scalable, and user-friendly public services that meet the needs of citizens and businesses.

Implications: To effectively implement the Use of standards, organisations must adopt and adhere to relevant standards and specifications throughout the design and development process. Business processes should include rigorous conformance assessments and validation steps to ensure compliance with selected standards. Technically, solutions must be designed to support interoperability and compatibility with established standards, including the use of specific protocols, formats, and interfaces. Continuous monitoring and evaluation are necessary to maintain compliance and address any emerging issues. The use of mechanisms and methods for analysing and assessing specifications against specific constraints or frameworks are valuable tools to ensure interoperable digital public services. The Common Assessment Method for Standards and Specifications (CAMSS) is an example of an action and set of solutions that can be used to carefully select and evaluate the candidate specifications.  Additionally, fostering a culture of adherence to standards and best practices is essential to ensure that all stakeholders understand and commit to the principle. Training and capacity-building initiatives should be implemented to equip staff with the knowledge and skills needed to apply standards effectively.

Statement: The design of digital public services is centred around their users.

Rationale: Users of European public services are meant to be any public administration, citizen or business accessing and benefiting from the use of these services. Users’ needs should be considered when determining which public services should be provided and how they should be delivered. Therefore, as far as possible, user needs and requirements should guide the design and development of public services.

Implications: A multi-channel service delivery approach, offering both physical and digital alternatives, is crucial in public service design, as users may prefer different channels depending on their circumstances. To facilitate access to public services and hide internal administrative complexity, a single point of contact should be available, especially when multiple bodies collaborate to provide a service. Users' feedback should be systematically collected, assessed, and utilised to design new public services and improve existing ones.
