Introduction
Freight transport (FT) encompasses the movement of goods within inland transport networks, primarily involving road transport between specific loading and unloading points.This process forms an integral part of the logistics chain, facilitating the transfer of goods across various distances and locations within a country or among countries.FT may be categorized into two main types: national and international road FT.National road FT is defined by the transportation of goods from one location to another within national borders, using a vehicle registered in that country.International road FT involves moving goods between two different countries, regardless of where the vehicle is registered.In the European Union (EU), road FT plays a critical role in the movement of goods within and among EU Member States, thus straightening the overall EU economy.According to the EU official statistics for 2022 (https://ec.europa.eu/eurostat/statisticsexplained/index.php?title=Road_freight_transport_statistics, accessed on 13 November 2023), road FT saw a 6.5% increase from 2020 to 2021, measured in tonne-kilometres (tkm).This growth followed a period of decline in 2020 due to COVID-19 lock-downs, particularly in the second quarter.However, in 2022, the total road freight transport in Europe remained constant at 1,920 billion tkm.Food products, beverages and tobacco led road freight transport in 2022 with 317 billion tkm, followed by grouped goods (228 billion tkm) and agricultural products (203 billion tkm).The most significant increases in tkm between 2021 and 2022 were observed for other goods (24.8%), equipment and material utilized in the transport of goods (7.4%), and mail/parcels (4.7%).The largest decreases were observed in furniture (−6.2%), chemicals, chemical products, and man-made fibres (−6.1%), and wood and products of wood and cork (−5.3%).
Despite its critical importance in the economy and trade, several sustainability concerns exist with respect to FT which are especially relevant to traffic accidents, elevated product costs, greenhouse gas emissions, and air and noise pollution [1].In addition, the FT sector remains predominantly reliant on paper-based processes, although several technological solutions exist for electronic document exchange [2].Especially in the case of EU road FT, one of the primary hurdles is the fragmented legal framework that spans the international, EU and national levels.This fragmentation results in inconsistent requirements for the acceptance of electronic documents by various authorities, creating a complex and often contradictory regulatory environment.Additionally, the IT infrastructure in this sector is also highly fragmented, characterized by non-interoperable systems and a lack of uniform standards for the exchange of electronic messages and documents.This technological disparity hinders seamless integration and communication.Furthermore, there is a significant issue with the acceptance of electronic documents among stakeholders.Many parties involved in FT are still not fully on board with adopting electronic documentation due to trust issues, a lack of awareness or the reluctance to change established practices.Combined, these factors create a challenging landscape for fully implementing eFTI, despite the clear advantages and long-standing availability of the necessary technological solutions [3].

Digital Initiatives Aimed at Modernizing and Streamlining Road FT
Arguably, the eFTI (Electronic Freight Transport Information) and the eCMR (Electronic Consignment Note for Road Transport) represent two pivotal digital initiatives focused on modernizing and streamlining road FT.In the sequence, a detailed background information framework on these initiatives is provided, encompassing their scope, outreach and benefits for the FT industry.

The Electronic Freight Transport Information (eFTI) Regulation
On 15 July 2020, the European Parliament and European Council adopted Regulation 2020/1056 on electronic Freight Transport Information (eFTI), aiming to improve the sustainability and efficiency of the transport sector in general while encouraging the digitization of supply chains (SC) and FT in particular.The new regulation establishes a legal framework for the electronic communication of regulatory information between the involved economic operators and FT stakeholders and the public authorities in relation to the transport of goods within the EU [4].The eFTI regulation will officially take effect on 21 August 2024.The eFTI includes cargo details, transport instructions and various types of documents to be exchanged and its goal is to improve efficiency and transparency by allowing for the quick and accurate exchange of information between all parties involved in the road FT ecosystem.eFTI is expected to minimize errors, improve security and increase the speed of FT.The implementation of eFTI can also help to reduce costs by automating processes, decreasing processing time and reducing the need for paper-based documentation [3].The key elements of this legal framework include the operational requirements applicable to eFTI platforms, which should be used by economic operators to make freight regulatory information available to competent authorities in electronic form in order to meet the conditions for the mandatory acceptance of this information by the competent authorities.The European Commission (EC) has released a draft for the eFTI system, offering EU Member States flexibility in its implementation while stressing adherence to ICT specifications.The regulation promotes reusing ICT systems that meet functionality and security standards, with Member States being responsible for their maintenance and security.It introduces eFTI Gates to enhance regulatory freight information exchange, aiming for efficiency and cost-effectiveness, and emphasizes interoperability and security through harmonized standards [5].
From an operational perspective, the eFTI has several objectives all revolving around enhancing the efficiency and security of freight transport within the EU through digital means.In particular, the eFTI system is designed to enforce adherence to international transport regulations.Authorities in the EU are mandated to accept transport information in electronic form, ensuring a unified approach to regulatory compliance across all Member States.eFTI also aims at unifying disparate resources into a consolidated network of information systems.This integration facilitates smoother interactions between partners and businesses in the FT ecosystem, thus streamlining operations across the logistics sector.Standardization is another important objective of the eFTI toward harmonizing the road FT processes and the electronic documents being exchanged, fostering a more uniform operating environment.By developing compatible and interconnected IT infrastructures, the eFTI regulation promotes enhanced collaboration.This allows SC partners to seamlessly exchange vital information, leading to better-coordinated logistics operations.The envisioned eFTI infrastructure is focused on high security and the immutability of data.It will provide transaction transparency while allowing for multiple control points, thus ensuring data integrity and preventing unauthorized alterations.All together, these objectives represent a concerted effort to digitize and enhance the EU's FT ecosystem, making it more cohesive, secure and efficient for all stakeholders involved.As depicted in Figure 1, the eFTI system is designed to facilitate the electronic exchange of information related to freight transport across different Member States, with a focus on interoperability, security and compliance with regulatory requirements.The involvement of multiple access points and the participation of various economic operators and service providers indicate a complex, multi-stakeholder environment.As depicted in Figure 2, the eFTI system is orchestrated to streamline the exchange of freight information, using digital tools to enhance efficiency and regulatory compliance.The logistical process begins with the entry of transport data to initiate the transfer of goods (Step 1).This information is then used to generate a unique identifier for the cargo, functioning as a digital bill of lading, which is critical for tracking and regulatory compliance (Step 2).This identifier is shared among businesses to facilitate business-tobusiness communication, allowing for the necessary processing and management of freight data (Steps 3-4).When required, this identifier, along with the associated transport details, is transmitted to control authorities, integrating the cargo information with regulatory oversight (Step 5).An official with the proper authorization accesses these data, utilizing their access rights to request and retrieve the relevant information within the system (Step 6).The system then conveys the pertinent data back to the official, streamlining the process of verification and compliance checks, and bringing the cycle of digital information exchange to completion (Steps 7-9).This sequence of steps showcases the eFTI system's role in improving the efficiency, transparency and regulatory adherence of FT within the digital ecosystem.The Electronic Consignment Note (e-CMR) is a digital version of the traditional Consignment Note (CMR) used in the international road transport of goods.The CMR is a legal document used to provide evidence of the contract of carriage between the carrier and the consignor.It contains information about the goods being transported, the parties involved and the route, and any special instructions.According to the United Nations Convention for the Carriage of Goods, consignment notes mainly appear in commercial transportation contracts.They are frequently utilized by customs and law enforcement agencies to verify goods and details related to the consignor, consignee and carrier in international trade.The digital version of the CMR Convention has been in effect since 2008 and has been ratified by 34 nations thus far.An e-CMR is an electronically generated document that is legally compliant and contains the same information as a traditional CMR.This means that an e-CMR has the same legal status as the traditional paper-based CMR and it can be used as evidence in case of disputes.It is created, transmitted and stored electronically, replacing the paper-based CMR.Therefore, it allows for the data to be shared in real-time between all parties involved in the transport of goods, including the carrier, consignor, consignee and any intermediaries.The eCMR represents a significant advancement in the logistics and transportation sector, particularly in Europe, driven by EU regulations as a part of a broader move toward paperless logistics.The eCMR functions as both a proof of delivery and a contract among the carrier, shipper and freight forwarder, detailing loading and unloading specifics, vehicle information, and supporting photo documentation and comments.It surpasses the traditional paper-based CMR's vulnerability to manipulation and manual handover by bolstering document reliability and security with digital tools, including secure electronic signatures.
The eCMR offers a multitude of benefits to the FT sector, primarily revolving around time savings, enhanced security and optimized administrative management.One of the key advantages of the eCMR is the significant reduction in the time spent managing documents.By enabling a single entry of information that is directly integrated with Transport Management Systems (TMS), it eliminates repetitive data transfers, thus boosting productivity.This digital approach not only facilitates the real-time tracking of goods, enhancing the traceability of transport, but also accelerates the invoicing process through the use of electronic signatures.This instant feedback mechanism is beneficial for both the client and the service provider, ensuring rapid billing once goods are delivered and incidents are reported in real time, which is crucial for insurance and liability purposes.Additionally, the eCMR contributes to the security and integrity of transport documents.With features like time-stamping and electronic signatures, the risk of falsification is greatly minimized compared with traditional paper documents, which are susceptible to loss, damage and fraud.This digital format also supports the growing trend toward "paperless" operations, leading to significant reductions in the use of ink, paper and postage, thereby lowering administrative costs and the environmental impact.The eCMR centralizes documentation, simplifying collection and archiving processes, and streamlines border controls with quick access to transportation information.Furthermore, it facilitates international document exchange, expedites the payment process by allowing for immediate invoicing post-delivery and simplifies the complaint procedure.The eCMR's capacity to provide real-time transport status updates and its potential for automation through computer software further enhance its value, making it a highly efficient and environmentally friendly solution in the transport sector.

Motivation and Contribution
The implementation of the eFTI regulation presents a significant shift in the FT industry, particularly in EU road transport.Despite the availability of numerous technological solutions for electronic document exchange, the road FT industry is faced with substantial challenges in applying these technologies, according to the literature [8][9][10].Besides, the current literature is narrow in scope and predominantly concentrates on the potential benefits and technological solutions for electronic document exchange in FT, as described in detail in Section 2.Moreover, there is a notable absence of relevant literature on eFTI, highlighting a substantial gap in comprehensively understanding and tackling the challenges associated with the implementation of eFTI regulation, particularly from an empirical perspective.Therefore, there is a clear need for empirical research that specifically investigates the practical difficulties, stakeholder experiences and operational realities of implementing eFTI in road FT.Such research would not only contribute to the academic discourse but also provide valuable insights for policymakers, industry practitioners and technology developers in refining and effectively implementing the eFTI regulation.Based on this gap in the literature, the following research questions are deemed relevant: 1.
What are the primary challenges and experiences associated with the implementation of eFTI in the road FT sector? 2.
How do regulatory frameworks impact the adoption and implementation of eFTI in road FT, and what specific challenges do they present?3.
What economic factors influence the decision-making process for adopting eFTI in road FT, and how do these factors shape the future outlook of digital technologies in the sector?
Therefore, the objective of this study is three-fold: (1) to identify and analyze the primary challenges and experiences reported by stakeholders in the road FT sector during the implementation of eFTI, (2) to evaluate the impact of regulatory frameworks on the adoption and effective implementation of eFTI in road FT, identifying specific regulatory challenges, and (3) to assess the economic factors affecting the decision to adopt eFTI in road FT, exploring the cost, return on investment and implications for future digital technology trends in the sector.In particular, our research contributes by offering empirical insights into the implementation challenges of the eFTI regulation, derived from interviews with a group of logistics experts.Utilizing a grounded theory approach, we delve into the perspectives of those directly involved in the logistics sector, uncovering nuanced understandings of the practical hurdles in adopting the eFTI regulation.Our findings reveal that the successful adoption of digital technologies like eFTI in logistics is contingent upon overcoming a range of challenges.These include bridging the digital skill gap within the workforce and ensuring system interoperability, which are critical for the seamless integration of new technologies into existing logistical processes.Furthermore, the research highlights the disparity in adoption processes between large and small companies.Economic factors, regulatory frameworks and the necessity for targeted training and leadership support are identified as pivotal elements that influence the digital transition.This disparity underscores the varying capacities and resources available to different-sized companies, suggesting that a one-size-fits-all approach may not be effective in implementing eFTI regulation.Our study, therefore, offers valuable insights into the multifaceted nature of digital adoption in the logistics sector, providing a more comprehensive understanding of the challenges and facilitating more targeted, effective strategies for the successful implementation of the eFTI regulation.
The remainder of this paper is structured as follows: Section 2 focuses on a comprehensive literature review that addresses the topic of electronic document exchange, especially focusing on the eFTI and eCMR regulations.In Section 3, the methodology that has been meticulously crafted for this study is delineated, paving the way for a well-rounded investigation into the subject matter.Moving forward, Section 4 brings forth the findings of our study, offering a lucid presentation of the data amassed.These results are subsequently analyzed and discussed in depth in Section 5, where we unravel the intricate layers of the research, fostering a rich dialogue around the findings.The paper ends with some concluding remarks.

Literature Review
Although numerous technological solutions are available for electronic document exchange, the road FT industry faces significant challenges regarding their application.Addressing these challenges requires collaboration among stakeholders, stringent laws, investment and responsiveness to demands [1].One solution is the concept of modal shift, which involves transitioning from road to rail, inland waterways and short sea shipping.This shift, as envisioned in European policies, aims to reduce the substantial external costs associated with FT, particularly its environmental impacts [11].Additionally, the integration of passenger and FT, termed as co-modality or cargo hitching, has been identified as an area needing more robust quantitative analyses and a normative framework for effective integration.This approach faces challenges such as varied research and policy issues [12].At last, the potential of Multimodal Freight Transport (MFT) is recognized for reducing external costs and improving efficiency.Despite its benefits, MFT faces barriers to implementation, categorized into areas like terminal, network, management, regulations, delivery characteristics and interoperability.Overcoming these barriers requires comprehensive strategies, aiding decision-makers in the transition toward MFT [13].
Technology and Information and Communication Technologies (ICTs) play a crucial role in enhancing the sustainability and reducing the negative impact of FT.The integration of real-time tracking, as explored by [14], demonstrates the potential for improving SC and logistics performance, though it is still in early stages.Meanwhile, the implementation of low-emission zones in Europe, as examined by [8], highlights the challenges and readiness of road FT to comply with sustainable mobility regulations, indicating a gap in the technological preparedness of current fleets.Ref. [15] emphasizes the importance of modern technologies in enhancing sustainability-focused road FT services, as well as improving quality management and competitiveness, based on survey data from 140 road FT firms [15].Ref. [16] investigates the potential of ICTs in mitigating environmental harm, particularly CO 2 emissions in various transportation modes, underscoring the effectiveness of telephone, mobile phone and internet technologies in promoting environmental sustainability.Last, Ref. [9] discusses the interaction between ICTs and road FT in mitigating environmental concerns, specifically focusing on reducing CO 2 emissions, highlighting the significant yet underutilized role of ICTs in addressing the environmental and health impacts of FT.Arguably, all these studies underscore the transformative potential of technology and ICT solutions in making FT more sustainable and less environmentally detrimental.
Regarding regulatory initiatives like eFTI and eCMR, the available literature primarily offers insights focused on their benefits.In the case of eCMR, Ref. [17] focuses on its operational and environmental benefits, emphasizing cost savings, time efficiency, carbon footprint reduction, real-time transparency and health safety during the COVID-19 pandemic.Ref. [18] highlights the financial and operational efficiency of eCMR, including faster paperwork, increased transparency and improved logistics efficiency.Refs.[19,20] provide the historical and legal contexts of the CMR Convention, foundational to understanding the transition to eCMR, but do not directly address eCMR benefits.Other studies have focused on the transition to electronic systems and their impact on efficiency and security.For instance, in [21], the authors develop a blockchain-based document management system for road transport.Their main objective is to enhance document security, data integrity and overall efficiency.Ref. [22] investigates decentralized freight declaration and tracking, aiming to increase data security and operational efficiency.The study demonstrates the effectiveness of decentralized systems in enhancing data security within logistics operations.Similarly, Ref. [23] explores the benefits of using electronic consignment notes in a manufacturing company, evaluating the financial and time savings it offers.The findings reveal significant cost and time efficiencies associated with the adoption of e-CMR.Ref. [24] analyzes the transition to electronic documents in road freight and assesses efficiency and data integrity.The study further highlights the advantages of e-documents in data accuracy and operational efficiency.An interesting concept in the eCMR-related literature is the concept of "neutralization".Neutralization in transport documents, particularly in relation to the CMR consignment note, involves the practice of replacing or exchanging original transport documents with others, nullifying their initial effect [25][26][27].This practice, not formally defined in commercial transport law, aims to obscure the actual movement of goods during transport, raising transparency and integrity concerns.Emerging primarily in European road FT, where the CMR note is prevalently used, neutralization challenges the reliability of these critical documents.Recent research suggests that new technologies, like smart tachographs, and the shift to electronic consignment notes could potentially mitigate this practice, enhancing the transparency and efficiency of international road freight transport [25].
In the case of eFTI, the available literature is relatively limited and not specifically focused on eFTI.For example, the authors in [10] discuss the challenges in logistics, including the need for timely information delivery across diverse entities with different IT systems and legal frameworks (including the eFTI).They propose the four-corner model as a solution to enable synchromodality, combined with digital twin concepts in logistics, improving the efficiency of operations and decision-making.The model focuses on interoperable, low-cost, reliable and secure data exchange between logistics stakeholders, without significant IT development requirements.In [28], the author references Regulation (EU) 2020/1056, which focuses on eFTI.While it doesn't provide specific details on the regulation, the reference indicates its relevance in the context of digital transformations in transport documentation, including the use of post-quantum digital signatures.
The analysis provided above underscores that the FT industry's journey toward sustainability and efficiency is characterized by a range of technological, policy, and regulatory challenges.In particular, the FT industry is exploring numerous technological solutions for electronic document exchange, yet faces significant challenges in applying these technologies effectively.Collaboration among stakeholders, stringent laws, investment, and responsiveness to demands are essential for overcoming these hurdles.MFT is recognized for its potential to enhance efficiency and reduce external costs.Despite its advantages, MFT's implementation faces barriers across terminal, network, management, regulations, delivery characteristics, and interoperability aspects.Comprehensive strategies are needed to guide decision-makers in transitioning toward MFT effectively.Regulatory initiatives like eFTI and eCMR provide operational and environmental advantages such as cost savings, time efficiency, carbon footprint reduction, real-time transparency and health safety.However, practices like "neutralization" in transport documents challenge the reliability of critical documents, suggesting that new technologies and electronic consignment notes could mitigate these issues, enhancing transparency and efficiency in international road FT.

Methodology
In our study, we applied the grounded theory (GT) methodology combined with expert interviews to investigate the implementation challenges of the eFTI regulation.We conducted structured interviews with selected experts from the logistics industry, focusing on eliciting detailed insights into the specific challenges and considerations surrounding eFTI implementation.The interview design was tailored to probe into various aspects of eFTI, while also allowing room for experts to introduce novel viewpoints and experiences.Following data collection, we embarked on an extensive GT coding process.This involved analyzing the expert interview transcripts in depth to extract key themes and patterns relevant to eFTI challenges.For conducting the analysis, we used qualitative analysis software (MAXQDA 2022).In the sequence, we provide a detailed description of the overall methodological approach.The set of questions used is presented in Table 1.GT is a significant qualitative research methodology that emphasizes theory generation directly from data, contrasting with hypothesis-testing in quantitative research [29,30].From a practical perspective, GT is a pivotal methodology in qualitative research revolving around coding as a key technique.This process involves identifying significant words or phrases from interview data, encapsulating them into codes, and iteratively building a coherent understanding of underlying themes.It is a method that efficiently shifts through data, highlighting core issues while filtering out less relevant information [30,31].GT's coding process aids in developing a coherent theory, addressing the complexity of handling voluminous qualitative data and discerning relevant themes and patterns, especially for those new to the methodology [29].Grounded theory, with its emphasis on theoretical sampling, constant comparison and theoretical saturation, offers a robust framework for deeply understanding complex phenomena, such as organizational structures.Comprehending the nuances of grounded theory is essential for maintaining high-quality research standards and effectively implementing this methodology [31][32][33][34][35]. GT also adapts to various research contexts, offering flexibility while maintaining rigorous qualitative analysis [31,36].
Implementing GT, however, is not without challenges, as highlighted by various scholars.The difficulty in achieving data saturation is a key challenge, especially for novice researchers.Ref. [37] delves into the nuances of data saturation, explaining that it occurs when no new information is discovered.This concept is crucial yet often difficult to grasp, particularly in determining the point of saturation in research.Additionally, Refs.[30,36] focus on the cognitive challenges in organizing and processing qualitative data.They emphasize the need for effective data management and interpretation strategies for the systematic development of GT.Furthermore, GT's iterative nature, involving constant comparison and theoretical sampling, adds to its complexity.Ref. [32] underscores the importance of these elements in maintaining research quality, stressing the need for empirical grounding throughout the study.Ref. [31] clarifies the method's philosophical underpinnings, aiding in methodological selection.Ref. [34] provides a practical guide to grounded theory's methodologies, making it more accessible for beginners.Ref. [38] examines the core principles of grounded theory, particularly the emergence of theories from data, offering a historical and philosophical perspective.Ref. [33] discusses the method's suitability for analyzing complex organizational structures, highlighting its benefits in providing contextually grounded insights.Finally, Ref. [35] aims to clarify issues and provide a clear, pragmatic guide, especially for novice researchers, covering the core principles and variations of grounded theory.
GT can be effectively combined with structured interviews from experts by using these interviews as a primary data source.The structured interviews provide detailed, expert insights, which are then analyzed through GT's coding and comparative methods to identify patterns, themes and relationships withing the underlying qualitative data.This approach allows for the development of theory that is deeply rooted in the specialized knowledge and experiences of experts, enriching the qualitative analysis and ensuring that the resulting theory is both grounded in data and reflective of expert perspectives.An important aspect when conducting interviews is the size of the sample (number of interviewees).According to the literature, working with a relatively small number of cases is often more effective.Such an approach allows for a deeper and more in-depth exploration of social phenomena, going beyond surface appearances and obvious meanings.This is true because in qualitative research, the importance is in understanding the dynamic qualities of situations rather than establishing statistically representative samples or proportional relationships among their components [39].

Expert Selection
In our research, the selection of experts has been meticulously made to encompass a broad spectrum of knowledge and expertise in the field, ensuring a comprehensive representation that includes both policy-level insights and hands-on experience.The sampling method used for expert selection in our study was based on non-probability sampling, particularly purposive sampling.This approach was necessitated by the specialized nature of our research topic, which demands experts with specific knowledge and experience in eFTI.By selecting individuals with expertise in the field of road FT and eFTI, we aimed to gather in-depth, relevant insights that probability sampling methods would not have provided.This decision aligns with the qualitative research design of our study, emphasizing the acquisition of detailed understanding and expertise over statistical representativeness.
Three experts were chosen to take part in our structured interviews.Expert A is Head of the Logistics Development Service in the Ministry of Development and Investment in Greece.Expert A has a deep understanding of the national logistics infrastructure and regulatory environment, especially relevant to how eFTI regulation aligns with national development strategies and investment plans.Expert A was chosen specifically to delve into the policy implications, explore the challenges and identify potential government support mechanisms critical for the effective implementation of eFTI regulation.Expert B holds a high-level managerial position in the Goods and Transport Council of the International Road Transport Union (IRU) as well as the Hellenic Federation of Road Transports.Expert B's involvement with the IRU ensures a broad, international perspective on logistics and transportation issues, which is crucial given the cross-border nature of road FT.Expert B's experience in the Hellenic Federation of Road Transports indicates an understanding of the specific challenges and opportunities within the Greek transport sector.Therefore, expert B is uniquely positioned to offer in-depth insights into the potential impact of eFTI regulation on road transport, encompassing both national and international dimensions.Moreover, they can provide expert perspectives on the industry's preparedness, as well as identify and analyze potential barriers to its adoption.Expert C is co-owner and managing director of a logistics company that deals with temperature-controlled and dry cargo transportation.Expert C brings a practical, ground-level perspective on the logistics sector.Expert C's experience in handling various types of cargo, including sensitive and perishable goods, offers valuable insights into the operational impacts of eFTI regulation.Being a member of the Greek National Logistics Council and the board of the Hellenic Logistics Association, Expert C provides insights into industry-wide perspectives and concerns and the readiness of logistics companies for the transition to eFTI systems, especially from a practical point of view.Together, these experts provide a comprehensive view of the eFTI regulation implementation from policy, industry and operational perspectives, making them highly suitable for interviews on this subject.In Table 2, we provide a detailed description of the experts' professional background and expertise.

Expert C
Co-owner and Managing Director of a logistics company covering transportation of temperature-controlled products as well as dry cargo.Member of the Greek National Logistics Council and the board of the Hellenic Logistics Association.Provides a practical perspective on the logistics sector, especially in the Greek economy.

Content Analysis and Validation
In order to perform the analysis, we utilized MAXQDA 2022, qualitative analysis software, in conjunction with the necessary steps for GT analysis specific to this software.The steps were the following: 1.
Coding the data: Coding involves assigning 'codes' or labels to qualitative data (in our case, transcriptions).Based on the theoretical underpinning of the GT, this process can be divided into two phases: (1) open coding, where new codes are created for specific data segments, emphasizing the need for an open mind to avoid limiting the number of codes, and (2) selective coding, in which the focus shifts to defining significant higher-level codes and sorting lower-level codes.

2.
Customizing the code system: Various subsequent coding rounds take place in which the researcher reviews the data using selective coding.Codes may be organized into hierarchies (parent codes and subcodes).

3.
Category building with creative coding: Categories are formed by clustering together concepts that are similar.This typically occurs during the later stages of the selective coding phase.These categories are crucial, as they lay the foundation for the structure of the emerging theory, mainly because they help to uncover and illustrate the theoretical connections between various concepts.4.
Constructing the theory: After selective coding, the theoretical links between categories become clearer.The next step involves theoretical sampling to develop the emerging theory, especially through depicting the various emerging categories.
For assessing the reliability of our methodology, we used the Holsti Coefficient.The Holsti Coefficient is a measure used in content analysis to assess the reliability of human coders in categorizing or coding qualitative data.This coefficient calculates the degree of agreement between two or more coders which independently classify or code the same content [40].The formula for the Holsti Coefficient is In Equation ( 1), N agreements is the number of coding agreements between coders, and N Coder A and N Coder B are the total coding decisions made by each coder, respectively.
In our case, two researchers conducted the qualitative analysis independently, resulting in the identification of themes within the transcript.The first researcher identified 7 themes; the second researcher, 6 themes.Notably, out of these identified themes, there were 5 themes that both researchers agreed upon as being relevant.Using Equation ( 1), the Holsti Coefficient has a value of approximately 0.77.The value reflects a strong consensus in identifying key themes in the data, suggesting that the coding process was quite consistent and reliable.While there are some differences in the themes identified by each researcher, a Holsti Coefficient of this magnitude generally signifies a robust qualitative analysis with a high degree of inter-coder reliability.
Recognizing the importance of a holistic approach to reliability assessment, we complemented our evaluation by incorporating additional metrics.These metrics serve as supplementary tools, offering nuanced insights into the consistency of our coding process without detracting from the primary analysis (Holsti Index).Consequently, we decided to incorporate Cohen's Kappa alongside the Holsti Index.Cohen's Kappa is a statistical measure that accounts for the possibility of agreement occurring by chance.It is calculated by considering the observed agreement between coders and the expected agreement if all coding was done randomly.Cohen's Kappa is particularly advantageous as it accounts for agreement occurring by chance, providing a more nuanced understanding of inter-rater reliability.This metric is especially pertinent when evaluating the precision of categorical data coding, as it offers a standardized measure of agreement adjusted for random chance.The calculated Cohen's Kappa value is approximately 0.62.Such a value indicates a substantial level of agreement between the researchers, beyond what would be expected by chance.This suggests that the coding scheme and its application by the researchers are both highly reliable.

Thematic Synthesis of the Various Implementation Challenges of the eFTI Regulation
The discussion with the group of experts revealed the actual challenges and the level of readiness of the different stakeholders to adopt the changes required for the implementation of eFTI.Based on the GT approach described earlier in detail, seven (7) thematic key areas have emerged, as seen in Figure 3.In particular, we used the following four coding steps pertinent to any GT approach: (1) Coding the data, (2) Customizing the code system, (3) Category building with creative coding and (4) Constructing the theory.In the sequence, a detailed analysis and synthesis of the findings is presented.

Technology Integration and Digital Transition
Focusing on technology integration and digital transition, the interviewees provided valuable insights into how the logistics sector is adapting to and integrating digital technologies, particularly eFTI.Three main sub-themes have emerged, namely the adoption of digital technologies, integration with existing systems and software integration over hardware:

•
Adoption of digital technologies: The logistics sector is in the midst of a significant shift toward digitalization, with technologies like eFTI being central.These technologies aim to digitalize the transport documentation process, making it more efficient and transparent.
• Integration with existing systems: A key aspect of this digital transition is the need to integrate these new technologies with existing TMS and Enterprise Resource Planning (ERP) systems.This integration is crucial for a seamless and efficient digital workflow.
The emphasis is on cloud-based solutions for their ease of access and use, indicating a move away from traditional, hardware-intensive setups.

•
Software integration over hardware: The focus is more on the integration of software and less on the acquisition of new hardware.The necessary hardware, like smartphones and tablets for drivers, is generally already in widespread use (mainly because of eCMR).This approach underlines a strategy where leveraging existing hardware with new software applications is seen as a cost-effective and practical method of digital adoption.

Challenges across Different Company Sizes
The interview with the experts shed light on how companies of varying sizes in the logistics sector are facing and managing the challenges associated with adopting digital technologies like eFTI.These sub-themes highlight the diverse challenges faced by companies of different sizes in integrating digital technologies.Larger companies, despite their resources, may encounter hurdles with existing complex systems, while smaller companies struggle more with the foundational aspects of digital transition, such as infrastructure and skill sets.The insights from the interviewees underscore the necessity of tailored strategies for digital adoption that consider the unique circumstances of each company, regardless of its size.Three main sub-themes have emerged, namely the varied capability for digital adoption, struggles of smaller companies and impact of company size on digital transition:

•
Varied capability for digital adoption: The ability and readiness to adopt digital approaches like eFTI in the logistics sector vary significantly between large and small companies.Larger companies tend to have more resources and more established administrative infrastructures and are often better positioned to integrate new technologies efficiently.

•
Struggles of smaller companies: Smaller companies, particularly individual transporters, face greater challenges.These include limited administrative infrastructure, a lack of digital skills and, often, a reliance on traditional methods.For many small transporters, especially in Greece, "the truck serves as their office", indicating a lack of traditional office-based infrastructure, which complicates the transition to digital systems like the eFTI.

•
Impact of company size on digital transition: The size of a company directly impacts its approach to and success in the digital transition.Larger companies can more easily navigate this change, while smaller entities struggle with both the technological and mindset shifts required.

Digital Skill Gap and Workforce Challenges
