ENAIRE’s own Four Lines Model is an organisational diagram that outlines the Entity’s oversight and control structure for risk management and regulatory compliance.
In the lower right-hand corner, a note indicates that this Four Lines Model is based on the IIA’s 2020 Three Lines Model, UNE-ISO 37000 Governance of organisations, ISO 37301 Compliance Management Systems, and ENAIRE’s Statute.
From an accessibility standpoint, this horizontal model clearly organises responsibilities, with the Governing Board as the governing body that must ensure that appropriate mechanisms are in place for reviewing and monitoring the Entity’s regulatory compliance and risks.
General structure and leadership: Governing Board and Senior Management
The diagram is arranged horizontally in columns, with ENAIRE’s governing body, the Governing Board, shown at the top as a horizontal block that spans and sits above the Directorate General and the columns representing the third and fourth lines:
- Governing Body: at the top of the structure is ENAIRE's governing body: the Governing Board.
- Delegation and oversight: The solid downward dark-blue arrows from the Governing Board to the Directorate General, the CECN/RSII and Internal Audit show how the Governing Board sets policies and strategies, delegates authority, allocates resources and exercises its supervisory responsibilities.
- Directorate General: the Director General coordinates the Management Committee and receives authority directly delegated by the Governing Board. Below the Director General are the two columns representing the roles of the first and second line.
- Delegation and oversight: the solid downward mid-blue arrows from the Directorate General to the first- and second-line columns illustrate how the Directorate General conveys and applies the policies and strategies set by the Governing Board, delegates authority, allocates resources and performs its supervisory role.
- Reporting and accountability: The solid upward dark-blue arrow from the Directorate General towards the Governing Board represents the Director General’s reporting and accountability to the Governing Board.
The Four Internal Assurance Lines
ENAIRE’s internal model is composed of four lines of regulatory-compliance assurance, arranged from left to right in the diagram:
1. First-line roles (first medium-blue column)
- Operational function: These consist of the operational client-service and support functions that are responsible for managing the risks inherent to their own activity while complying with the applicable regulations.
- First-line roles at ENAIRE include the central-services directorates and the regional directorates, as well as all their subordinate units.
- Reporting and accountability: They report directly to the Director General, represented by the medium-blue upward vertical arrow.
2. Second-line roles (second medium-blue column)
- Specialised risk-supervision and support function: these functions have the knowledge, experience and authority in specific areas of risk. Their role is to support, supervise and challenge risk management and regulatory compliance in order to achieve objectives and continuous improvement in their respective areas.
- Second-line roles at ENAIRE include the specialised units and committees in areas such as safety, quality, environment, occupational health and safety, data protection and legal advisory services.
- Reporting and accountability: They report directly to the Director General, represented by the medium-blue upward vertical arrow.
3. Third-line roles (third light-blue column)
- Regulatory Compliance Function: this line is composed of the Ethics and Regulatory Compliance Committee (CECN) and the Head of the Internal Reporting System (RSII).
- Independence: these are independent bodies with direct access to the Governing Board, ensuring their objectivity.
- Role: they provide expertise and authority in risk management, ethics and regulatory compliance (criminal and competition); they support, supervise and challenge risk management and regulatory compliance to drive continuous improvement. The RSII reports on the management of the information received through the Internal Reporting System, guaranteeing confidentiality.
- Reporting and accountability: It reports directly to the Governing Board, represented by the dark-blue upward vertical arrow.
4. Fourth-line roles (fourth orange column)
- Internal-assurance function performed by Internal Audit.
- Independence: Internal Audit exercises an independent and objective function. Its direct access to the Governing Board ensures its independence.
- Role: it provides assurance and guidance on the adequacy and effectiveness of governance and risk management, and governance and regulatory-compliance management, promoting the achievement of objectives and continuous improvement.
- Reporting and accountability: It reports directly to the Governing Board, represented by the dark-blue upward vertical arrow.
Alignment and collaboration (side lines)
The diagram shows grey dashed lateral arrows representing alignment, communication, coordination and collaboration between the Directorate General and the various assurance lines.
External assurance providers
Outside the four internal lines, there is a lateral column on the right representing External Assurance Providers. These providers deliver assurance through external audits, certification audits and inspections.
