                <p>The uptake of digital business models has been distinctly evident over the recent years, causing profound changes across industries. Even though various scholarly papers attempt to investigate those developments, empirical studies of factors that influence digital business models’ maturity are still scarce. This research paper aims to address this literature gap, achieved by empirically testing the relationship between relevant managerial factors and digital business models maturity. Through a multi-national study with 162 participating companies operating within the sector of yachting tourism, followed by a qualitative and quantitative analysis of the obtained primary results, it has been found that managerial competencies, including management education and their digital skills, positively affect digital business model maturity of the respective companies.

            <label>INTRODUCTION</label>
            <p>As a consequence of rapid digitization, in recent years, one could have witnessed a
                series of radical business model shifts in numerous business sectors, particularly
                the flourishing of what has been denoted as Digital Business Models <xref
                    ref-type="bibr" rid="r1">1</xref>. Such developments have caused considerable
                changes in business ecosystems across industries and geographies <xref
                    ref-type="bibr" rid="r2">2</xref>, resulting in how services are provided and
                created value <xref ref-type="bibr" rid="r1">1</xref>, <xref ref-type="bibr"
                    rid="r3">3</xref>. In a nutshell, digital business models are those business
                models that create and deliver value primarily by using digital technologies <xref
                    ref-type="bibr" rid="r4">4</xref>, <xref ref-type="bibr" rid="r5">5</xref>.
                Prior research, e.g. <xref ref-type="bibr" rid="r6">6</xref>-<xref ref-type="bibr"
                    rid="r9">9</xref>, has identified several distinct specificities of digital
                business models, such as value creation, innovation, or ability to use digital
                technologies, fostering their unparalleled growth and impact. Furthermore, to
                provide a more in-depth understanding of the development level of a particular
                business model, the concept of digital business model maturity has been introduced
                and studied (e.g. <xref ref-type="bibr" rid="r10">10</xref>, <xref ref-type="bibr"
                    rid="r11">11</xref>). In addition, a specific measurement framework for digital
                business model maturity has been proposed and empirically validated <xref
                    ref-type="bibr" rid="r12">12</xref>. While previous research have stressed that
                the digital business model is connected with the concept of digital transformation
                    <xref ref-type="bibr" rid="r13">13</xref> and explored various factors that may
                influence a company's digital business model maturity level, such as the adoption of
                digital technologies <xref ref-type="bibr" rid="r14">14</xref> or organizational
                readiness <xref ref-type="bibr" rid="r15">15</xref>, this paper is focusing
                specifically on the managerial factors identified as potentially highly relevant
                (e.g., <xref ref-type="bibr" rid="r16">16</xref>, <xref ref-type="bibr" rid="r17"
                    >17</xref>). Therefore, the study empirically examines managerial factors that
                may impact the digital business model maturity, especially in the context of Small
                and Medium Enterprises (SMEs) as the most numerous type of business organization.
                The research question is formulated as follows: What is the effect of managerial
                factors on the digital business model maturity of an SME? The above research
                question has been explored within this paper through a combination of theoretical
                analysis and empirical research - coupled with an in-depth quantitative and
                qualitative study of the obtained findings and their relevant interrelations. In
                that context, the main scientific contribution of this paper involves empirical
                testing and validation of the impacts of managerial factors on digital business
                model maturity. In addition, an important contribution is reflected in the fact that
                this research explores the prevailing SME segment, as opposed to the majority of
                earlier studies that focused predominantly on the corporate segment. As the growing
                number of companies are trying to shift to the digital business model, which
                appeared to be very important,the , especially in the Covid-19 pandemic environment,
                this paper's results might help practitioners focus on specific factors in achieving
                digital business model maturity. The remainder of this paper has been outlined as
                follows: Section II contains theoretical background based on a structured literature
                review of prior studies about digital business models and their maturity and the
                relevant managerial factors. Section III describes the used methodology for the
                empirical research, including the data collection process, variables used in the
                study, their measurement, and the formulation of the hypotheses and the
                corresponding research model. Next, Section IV outlines and analyzes the obtained
                research results, starting with the frequency analysis and descriptive statistics,
                the analysis of correlations, and finally, the testing of the three hypotheses.
                Towards the end of the paper, Section V summarizes the relevant findings and
                discusses their implications, pointing to the possible application in academia and
                practice and suggesting the potential directions of future research. </p>

            <p>Digitalization that we are witnessing in recent years and decades represents the
                greatest systematic social and economic change since the time of the industrial
                revolution <xref ref-type="bibr" rid="r6">6</xref>. Accordingly, companies in all
                industries are increasingly becoming digitized and re-organized into new forms of
                digital organizations <xref ref-type="bibr" rid="r16">16</xref>; hence the role of
                digital business models are becoming ever more prominent. Such developments have
                spurred academic interest, including the studies of the characteristics of digital
                business models and their maturity and the role of leadership in that new context. </p>
            <p>THE RISE OF DIGITAL BUSINESS MODELS </p>
            <p>In recent years one could witness a sharp growth of research papers related to
                digital business models <xref ref-type="bibr" rid="r18">18</xref>, following a rapid
                uptake of the popularity, prevalence, and market impact of such business models in
                practice <xref ref-type="bibr" rid="r2">2</xref>. Layers of technological innovation
                have enabled a galloping pace of digital transformation within business
                organizations <xref ref-type="bibr" rid="r9">9</xref> and the related transformation
                of entire industries and markets. Such developments are a part of a wider trend
                labeled a digital revolution <xref ref-type="bibr" rid="r2">2</xref>, pointing to
                the broad and profound societal and organizational effects of the intense changes
                worldwide. The term digital business model stands for a specific business model,
                where value creation and delivery are achieved mainly through digital technologies
                    <xref ref-type="bibr" rid="r4">4</xref>. Authors have emphasized several notable
                characteristics of digital business models that describe them in further detail and
                differentiate them from the traditional business models. These characteristics have
                been illustrated in Table 1. </p>

            <p>Table 1 indicates that it can be inferred that they have enabled new value
                propositions, faster pace of business innovation, and in general, fostered the
                opening of completely new business frontiers and new markets, including creating
                specific business ecosystems <xref ref-type="bibr" rid="r2">2</xref>. Furthermore,
                the digital business model is tightly related to digital transformation <xref
                    ref-type="bibr" rid="r13">13</xref>. This highly pervading concept stands for
                extensive organizational changes connected to the implementation of digital
                technologies <xref ref-type="bibr" rid="r15">15</xref>, frequently resulting in a
                thorough transformation of the company involved <xref ref-type="bibr" rid="r22"
                    >22</xref>. In the course of digital transformation, the company is typically
                pursuing innovation of its services and business models <xref ref-type="bibr"
                    rid="r14">14</xref>, along with the profound shifts of the organizational culture
                and a range of other effects on the entire company <xref ref-type="bibr" rid="r23"
                    >23</xref> as well as a business ecosystem <xref ref-type="bibr" rid="r15"
                    >15</xref>. Several frameworks have been in use for that purpose regarding the
                components of digital business models and their visual representation, as summarized
                in <xref ref-type="bibr" rid="r18">18</xref>. In brief, the most frequently applied
                framework is the Business Model Canvas (BMC) developed by Osterwalder &#38; Pigneur
                    <xref ref-type="bibr" rid="r24">24</xref>, which can be used for representing
                both digital and traditional business models. The central element of BMC is the
                Value Proposition, around which the entire business model revolves with its 9
                interrelated elements. Weill &#38; Woerner <xref ref-type="bibr" rid="r2">2</xref>
                is an especially relevant framework, which depicts a digital business model as a
                combination of three main components. These components are i) Content – digital
                information about products and services, and in some business models digital-only
                products, ii) Experience – including digital customer interfaces, customer-facing
                processes, etc., and iii) Platform – including a range of internal and external
                technologies and data. Such components are highly relevant for digital business
                models, and they can be used to study their development <xref ref-type="bibr"
                    rid="r2">2</xref> and their maturity <xref ref-type="bibr" rid="r12">12</xref>.
                It should be noted that digital business models are subject to continuous
                optimization, development, and improvement. In this context, Muzellec et al. <xref
                    ref-type="bibr" rid="r10">10</xref> point to the concept of the Business Model
                Lifecycle, emphasizing that businesses should continuously review the relevance of
                their digital business models and adapt them dynamically to changes in customer
                response to their value proposition and other relevant parameters. It is, therefore,
                a matter of continuous business modeling and the systematic testing of the changes
                made. Other authors, such as Weiner &#38; Wiesbecker <xref ref-type="bibr" rid="r25"
                    >25</xref>, agree with this approach, pointing out the need to permanently
                design and evaluate business model table-wrap and continuously check whether
                customers and partners perceive the value provided in the way the company envisioned
                it. These authors also elaborate on several targeted questions about value
                proposition, customers, the role of partners, and key financial aspects, which the
                companies should regularly evaluate in developing and upgrading their digital
                business model. </p>
            <p>DIGITAL BUSINESS MODEL MATURITY </p>
            <p>The development level of a particular digital business model in a company is called
                digital business model maturity <xref ref-type="bibr" rid="r12">12</xref>. Measuring
                and improving the maturity of one's digital business model can be of particular
                importance when considering its presumed links to organizational performance.
                According to Debkowska <xref ref-type="bibr" rid="r26">26</xref>, companies with a
                higher business model maturity typically achieve better financial results. An
                analogous conclusion can be derived from the work of Weil &#38; Woerner <xref
                    ref-type="bibr" rid="r2">2</xref>,<xref ref-type="bibr" rid="r27">27</xref>. As a
                relatively recent field of academic study, the concept of digital business model
                maturity has been most frequently observed from a predominantly theoretical
                perspective. At the same time, several papers contain empirical studies in that
                regard. Furthermore, a common approach involves grouping companies according to
                predefined digital maturity stages (e.g. <xref ref-type="bibr" rid="r28"
                    >28</xref>-<xref ref-type="bibr" rid="r30">30</xref>). Another approach compares
                companies' business models to an envisioned ideal development level. One such
                example can be found in <xref ref-type="bibr" rid="r11">11</xref>, who pointed out
                that industrial companies' highest digital business models maturity was observed for
                business models based on smart services. Alhava et al. <xref ref-type="bibr"
                    rid="r31">31</xref> state that digital business models of multisided platforms
                are generally more mature than those with a linear value chain. A framework for the
                empirical measurement of digital business models maturity has been described in
                    <xref ref-type="bibr" rid="r12">12</xref>, and it will be correspondingly used in
                this study, as described in the next sections. Regarding the staged approach,
                Muzellec et al. <xref ref-type="bibr" rid="r10">10</xref> have identified four
                stages, or levels, of digital business models' maturity of two-sided platforms.
                Likewise, Sehnem et al. <xref ref-type="bibr" rid="r32">32</xref> have defined five
                stages of business model maturity from the circular economy perspective. In this
                research and digital maturity stages, Kane et al. <xref ref-type="bibr" rid="r29"
                    >29</xref> can find a particularly interesting perspective, whose results
                indicate that the companies in the lowest digital maturity group are often
                characterized by an insufficient managerial understanding of digital technologies
                and business. Similar findings are evident from the work of Berghaus &#38; Back
                    <xref ref-type="bibr" rid="r28">28</xref>, where managerial understanding and
                support are found necessary for the company to move beyond stage 1 of digital
                maturity. Gill &#38; Van Boskirk <xref ref-type="bibr" rid="r30">30</xref> have
                emphasized the role of developing digital skills for successful mastery of
                mid-stages of digital maturity. Similar importance to digital skills has also been
                given in <xref ref-type="bibr" rid="r29">29</xref>. </p>
            <p>MANAGERIAL FACTORS </p>
            <p>The relevant literature has increasingly mentioned the crucial role of the company's
                management in digital transformation and the corresponding digital business models.
                In particular, Promsri <xref ref-type="bibr" rid="r33">33</xref> points out that
                leadership is a key factor for successful digital transformation and proceeds by
                identifying managers' digital knowledge and literacy as one of the necessary
                prerequisites in that context. Similarly, Borowska <xref ref-type="bibr" rid="r34"
                    >34</xref> suggests that continuous digital leadership is required and describes
                the necessity for digital leaders to develop and implement adequate strategies which
                would ensure relevant skills development, adoption of organizational changes
                adjusted to the digital age, as well as the active use of digital tools across the
                organization. Peter et al. <xref ref-type="bibr" rid="r35">35</xref> articulate that
                digital leadership is one of the core strategic fields for digital transformation,
                which needs to provide adequate conditions for creating and utilizing dynamic
                capabilities within the organization. In essence, the authors agree that there has
                been a substantial change in leadership styles and requirements in the digital era
                    <xref ref-type="bibr" rid="r36">36</xref>-<xref ref-type="bibr" rid="r38"
                    >38</xref>, whereby the later authors have outlined a specific matrix with
                different digital leadership styles. Furthermore, to develop an adequate digital
                leadership capacity, managers need to achieve a certain level of digital literacy,
                involving the mastery of relevant technical language and concepts <xref
                    ref-type="bibr" rid="r39">39</xref>. These findings imply that the company
                management should present specific know-how about digital technologies and business
                models. In addition, Tanniru <xref ref-type="bibr" rid="r40">40</xref> emphasizes the
                close interrelation between technological and business aspects of digital
                leadership. Finally, according to the research conducted by Larjovuori et al. <xref
                    ref-type="bibr" rid="r41">41</xref>, formulating an adequate digital strategy is
                central to digital transformation success, including a clear vision, adequate
                objectives, and consistent managerial support during the implementation process. The
                above-described results indicate that the relevant aspects of managerial
                competencies include acquiring specific knowledge and developing the ability to
                combine various business and technical aspects and successfully set and implement a
                winning digital strategy. Such managerial competencies and skills have been related
                to the success of the overall digital transformation and the company's digital
                maturity level. In particular, companies with strong managerial competencies were
                also on higher stages of digital maturity <xref ref-type="bibr" rid="r16">16</xref>,
                    <xref ref-type="bibr" rid="r17">17</xref>, which indicates a connection between
                such managerial factors the digital maturity concept. </p>

        <sec sec-type="METHODOLOGY AND APPROACH">
            <label>METHODOLOGY AND APPROACH</label>
            <p>The empirical study was conducted using a structured online survey questionnaire on a
                multi-national sample of 162 companies based in 42 different countries and five
                continents. The companies from the same business sector were involved in the
                research. In particular, the selected sector was yachting tourism, which has been
                chosen for this study for several reasons: a high share of digital business models,
                the substantial role of digital business models in tourism overall according to
                extant research <xref ref-type="bibr" rid="r18">18</xref>, authors' prior familiarity
                with this sector, the possibility to obtain relevant international population data,
                as well as the fact that the companies in this sector are usually SMEs (Small and
                Medium Enterprises), which further enhances their comparability in the context of
                this research. </p>
            <p>DATA COLLECTION PROCESS </p>
            <p>The core information regarding the data collection process is laid out in Table 2,
                summarizing the main parameters of the field research. The lists of companies were
                obtained from available sectors’ databases and global reservation systems
                specialized for this particular business segment (MMK Booking Manager and Nausys).
                Next, those lists have been rigorously checked and amended following a structured
                relevance-assessment process, thus resulting in the final database of relevant
                companies and their contact details. In particular, the population consisted of 932
                companies distributed across the world, which have all been invited to participate
                in the study. It should be noted that the sample included companies from all
                continents except Africa and Antarctica, which is because the yachting tourism
                sector is not present to a sufficient extent on those two continents. </p>

            <p>As visible from Table 2, the survey was administered online. In particular, the
                invited companies have been contacted primarily by e-mail, and in addition, some
                have been contacted through relevant social networks. The process included several
                professional reminders over approximately two months, resulting in 172 filled
                questionnaires. However, a few questionnaires had to be removed for not adhering to
                the required criteria (such as removing the duplicates, etc.). The final sample of
                162 relevant and complete questionnaires was established. These 162 companies and
                their responses have been the subject of quantitative and qualitative analysis in
                this study. It should also be noted that the vast majority of the actual respondents
                were either managers or owners of those companies, which implies that they are
                adequately familiarized with their companies' business models and the studied
                managerial factors. The collected questionnaires were first analyzed for
                completeness and relevance, after which several steps of statistical analyses have
                been performed, as described in the following sections. It should also be noted that
                some respondents have sent their additional comments in the form of free text, which
                have been of further help to the authors to understand better the subject matter and
                the challenges present in the field. Finally, it needs to be mentioned that in
                addition to the main research instrument, the authors have also used supplementary
                sources such as a review of the websites and social network profiles of the studied
                companies and their competitors to observe a wider perspective and improve the
                contextualization of the obtained research findings. </p>
            <p>VARIABLES IN THE STUDY </p>
            <p>Table 3 summarizes the research variables, which were defined following prior
                literature. In particular, the upper part of the table describes the constructs that
                measure relevant managerial factors, while the lower part contains constructs
                measuring digital business models maturity and its components. </p>

            <p>As described below, the study used these variables to postulate and test the
                hypotheses and the corresponding research model. </p>
            <p>RESEARCH HYPOTHESES </p>
            <p>Three hypotheses have been postulated and empirically tested in this paper. The first
                hypothesis examines the effect of managerial factors on digital business model
                maturity, while the remaining two hypotheses focus on specific impacts of the
                particular managerial factors studied. Specifically, the first hypothesis has been
                developed in line with the prior work of Peter et al. <xref ref-type="bibr" rid="r35"
                    >35</xref>, Borowska <xref ref-type="bibr" rid="r34">34</xref>, and Promsri <xref
                    ref-type="bibr" rid="r33">33</xref>, who all articulated the highly important
                role of leaders in the success of their companies’ digital transformation endeavors.
                It has been argued that digital leadership is a core strategic aspect of businesses’
                digital transformation <xref ref-type="bibr" rid="r33">33</xref>, essential for
                providing adequate conditions for the organization to explore its digital
                capabilities successfully. Such prior findings are highly relevant in the context of
                this research, as the observed population consists mostly of SMEs, where the role of
                management is of particular importance. Likewise, Schwer et al. <xref

                leadership for achieving digital maturity. In this context, managerial factors can
                be expected to impact the maturity of digital business models positively, and
                therefore, the first hypothesis in this research is postulated as follows: H1:
                Managerial factors affect the digital business models maturity. The second
                hypothesis examines the impact of management education on the maturity of their
                company’s digital business model. Promsri <xref ref-type="bibr" rid="r33">33</xref>
                has identified managers' digital knowledge and literacy as one of the necessary
                prerequisites for a successful digital transformation. Likewise, according to <xref
                    ref-type="bibr" rid="r16">16</xref>, <xref ref-type="bibr" rid="r17">17</xref>,
                companies with strong managerial competencies were also in higher stages of digital
                maturity. Considering such research, it can be reasonably hypothesized that the
                relevant management education will be expected to impact digital business models'
                maturity positively. Thus, the second hypothesis in this study is stated as follows: </p>
            <p>H2: There is a positive impact of management education on digital business model's
                maturity. Finally, the third hypothesis explores the effect of digital skills of
                managers on their organization’s digital business model maturity. According to
                extant research, managers need to develop sufficient digital literacy to achieve
                adequate digital leadership capacity, including the mastery of relevant technical
                language and concepts <xref ref-type="bibr" rid="r39">39</xref>. These findings imply
                that the company leaders should be well versed in specific know-how about digital
                technologies and business models. The necessity to combine technological and
                business aspects of digital leadership has been noted in <xref ref-type="bibr"
                    rid="r40">40</xref>. In contrast, Gonciarski &#38; Swiatkowski <xref
                    ref-type="bibr" rid="r36">36</xref> have documented a substantial change in
                leadership styles in the digital era, which implies the utilization of specific
                digital skills. Based on such prior findings, the important role of managers’
                digital skills becomes evident. It can be reasonably expected for the management
                digital skills to positively impact the maturity of their companies’ digital
                business models. Therefore, the third hypothesis in this research is formulated as
                follows: </p>
            <p>H3: Management digital skills positively affect the digital business models maturity.
                Those three hypotheses and their interrelations in the research model, as
                illustrated in Figure 1. <fig id="g1" orientation="portrait" position="float">

                </fig> In the next sections, we summarize the empirical testing of these hypotheses
                on companies within the observed industry to examine the validity of the research
                model and enable further studies with samples from other comparable industries.
                VARIABLES MEASUREMENT APPROACH</p>
            <p>Each variable has been measured with a set of specific questions in this research,
                using the 5-point Likert scale - a frequently applied method in comparable studies.
                Specifically, variables of digital business models maturity have been measured
                according to the framework displayed in Figure 2. As can be observed from that
                illustration, the digital business model maturity level was obtained by measuring
                the achieved development stage of each of the three components: Content, Experience,
                and Platform. The actual measurement questions have been analogous to <xref
                    ref-type="bibr" rid="r12">12</xref> and based on the previous work<xref
                    ref-type="bibr" rid="r2">2</xref>. Likewise, the variables about the studied
                managerial factors have also been measured through a set of specific statements -
                indicators, as presented in Figure 3. Regarding the presented measurement
                frameworks, it should be noted that a statistical evaluation of the measurement
                model reliability was conducted following widely used procedures incomparable
                research. Specifically, the reliability of the measurement model was evaluated with
                the use of the Cronbach Alpha coefficient, which is one of the most frequently used
                measures of reliability in similar studies <xref ref-type="bibr" rid="r42">42</xref>.
                The results of those calculations are outlined in Table 4. <fig id="g2"

            <p>*result after the removal of M1 indicator </p>
            <p>As shown in Table 4, for all maturity-related constructs, the corresponding Cronbach
                Alpha coefficients are around 0,9, while for managerial factors constructs, they
                range from nearly 0,7 to over 0,9. Such Cronbach Alpha coefficients indicate that
                the measurement model reliability in this research is satisfactory. It should be
                noted that the displayed coefficient for the EDU variable has been obtained after
                removing the M1 indicator. Namely, that particular indicator was insufficiently
                consistent with the rest of the measurement model and therefore has been removed
                from the corresponding structural model, following the usual procedure of
                incomparable research. The remaining indicators were found to be reliable in the
                context of this measurement model, and therefore no further indicators had to be
                removed. </p>
        </sec>
        <sec sec-type="RESULTS">
            <label>RESULTS</label>
            <p>The statistical analysis of the collected responses has encompassed the univariate
                analysis (e.g., response frequency distributions and descriptive statistics) and the
                multivariate analysis, particularly based on the structural equations modeling
                technique. Furthermore, extensive correlations analyses have been performed, both at
                indicators and constructs. In addition, the potential improvement areas with regards
                to managerial factors have been identified in this study. </p>
            <p>DESCRIPTIVE STATISTICS </p>
            <p>The observed frequency distributions for the studied managerial factors are presented
                in Appendix A – Table A1. for EDU and DGS indicators. The upper part of the table
                contains frequency distribution for EDU – Management Education indicators. It can be
                observed that all of those indicators are right-skewed, which indicates that the
                respondents rate quite positively the educational aspects of their company
                management. In particular, the highest number of "I fully agree" answers has been
                recorded for the indicator M1 (university diplomas). In contrast, the lowest number
                of such responses is evident for M4 (education relevant for digital business and
                technologies). It should be noted that the indicator M1 was subsequently excluded
                from the structural modeling part of the analysis due to the findings of the
                measurement model reliability analysis, as already explained in the previous
                section. The lower part of the same table contains frequency distributions for DSK –
                Management Digital Skills indicators. It is interesting to note that the indicators
                S1-S4 have relatively similar distribution shapes: all are skewed positively with
                the highest score for the "I mostly agree" option, which over 60 respondents
                selected in each of those questions. However, when looking at the "I fully agree"
                answers, one can notice a solid difference between indicators S1 and S2. This
                implies that the participants have given quite higher ratings to their management's
                general understanding of the new digital trends and technologies than their actual
                knowledge to lead a digital strategy. It can be observed that the results for the S5
                indicator differ substantially from the other four DSK indicators. The S5 frequency
                distribution is only mildly positively skewed, with the majority of the answers
                being neutral. This is logical given that this indicator tackles the managers'
                digital skills compared to the competition. Most of the respondents believe to be
                neither particularly better nor worse compared to the digital skills of the
                competitor's management. Selected descriptive statistics for the studied managerial
                factors have been displayed in Table 5. Initially, it should be noted that the
                individual numerical values, as a base of this calculation, have been obtained by
                transforming the descriptive Likert-scale answers into corresponding numerical
                scores, ranging from 1 (for "I fully disagree" answers) to 5 (for "I fully agree"
                answers). Thus obtained numerical values have been the basis for further statistical
                analysis. In particular, from the upper part of Table 5, about management education,
                one can observe that the indicators M1 and M3 have very high mean values. In
                contrast, the lowest mean has been recorded for the indicator M4. This may imply a
                certain room for improvement in managers' education about digital business and
                technologies. When it comes to DSK indicators, as visible from the lower part of the
                table, the highest mean score has been obtained for S1 and the lowest for the S5
                indicator. The S5 means is somewhat above the middle of the measurement scale,
                indicating that the respondents may have assessed themselves overly positively
                compared to the competition. As for the remaining DSK indicators, one can notice a
                certain discrepancy between a general statement such as S1 and more practical
                statements such as S2 and S3, which may indicate a potential area for improvement
                when it comes to managers' knowledge to lead a digital strategy and their actual
                participation in developing and implementing it. </p>

            <p>Overall, it can be observed that the participants rated themselves rather highly for
                all of the studied indicators, which is logical when considering that the vast
                majority of the respondents in this study were the managers themselves. Therefore,
                when interpreting the numerical results, one needs to consider the possibility of
                some bias towards more positive answers in general. In this context, it is obvious
                that the surveyed managers have rated their knowledge and skills partly (and those
                of their other colleagues); hence the high mean values are not surprising.
                Considering such conditions, the identified potential improvement areas with
                relatively lower average scores than other indicators may be relevant, even though
                those scores are nominally high. The correlations between the measured indicators
                have been analyzed using Pearson correlation coefficients, a frequently used measure
                of association <xref ref-type="bibr" rid="r43">43</xref>. This part of the analysis
                examines the nature and the direction of mutual connections between the studied
                indicators and the respective constructs. The correlations coefficients for each
                pair of indicators of the studied managerial factors are presented in Table 6. From
                the data presented, it can be observed that all those correlations are positive and
                statistically significant at the level of 1 %. Regarding the strength of the mutual
                correlations, it should be borne in mind that the closer the correlation coefficient
                to 1, the stronger the positive Correlation between that pair of indicators or
                variables <xref ref-type="bibr" rid="r43">43</xref>. This implies that most of the
                observed indicators have correlations of medium strength. Yet, some pairs of
                indicators (such as S1 and S2, for example) have a rather strong positive
                correlation. </p>

                correlation analysis between the constructs, i.e., between the studied managerial

                statistically significant at the level of 1 %. Such results imply that the companies
                with higher scores on managerial factors are likely also to have higher scores on
                their digital business model maturity. Overall, the presented correlation analysis
                results suggest that positive relationships exist between the variables in the

            <p>Next, we present relevant structural models for the hypotheses testing, displayed in
                Figure 4, along with the estimated parameters. It should be noted that the model
                parameters were estimated using the ML - Maximum Likelihood method. The most
                relevant parameters for testing the hypotheses are those in the middle of the
                structural model, connecting the two main constructs. In particular, the regular
                parameter is displayed above the arrow, while the corresponding standardized
                parameter is displayed in brackets below that arrow. All the estimated parameters
                were statistically significant at 1 % in all three structural models. Regarding the
                structural model for hypothesis H1, the obtained parameters indicate that the
                relationship between managerial factors and digital business model maturity is
                characterized by a positive and statistically significant coefficient of 0,99,
                corresponding to the standardized coefficient of 0,66. This means that the higher
                the company's score on managerial factors, the higher the expected level of its
                digital business model maturity. This result implies that hypothesis H1 has been
                empirically confirmed in this research. <fig id="g4" orientation="portrait"
                    position="float">
                    <label>Figure 4. Structural models with estimated parameters.</label>
                    <graphic xlink:href="indecs-20-514-g4.png"/>
                </fig> For hypothesis H2, the estimated parameter connecting the two constructs is
                0,46 (standardized 0,37), implying a positive connection between management
                education and digital business model maturity. The estimated parameters in the model
                are statistically significant. Therefore, should the score on managerial education
                increase, one could expect, on average, that the company's score on digital business
                model maturity would increase as well. This concludes that hypothesis H2 has also
                been confirmed empirically in this study. Finally, looking at the structural model
                for H3, it can be observed that the constructs are connected with a positive
                parameter of 0,62, which corresponds to the standardized parameter of 0,63. As these
                estimated parameters are statistically significant, too, this implies that an
                increase in score for the management digital skills would lead to an expected
                increase in the score for digital business model maturity of the company. In light
                of such results, it can be inferred that hypotheses H3 have been confirmed. </p>

        <sec sec-type="DISCUSSION AND CONCLUSIONS">
            <label>DISCUSSION AND CONCLUSIONS</label>
            <p>This paper explored digital business model maturity and the managerial factors
                affecting it, focusing on the particular context of SMEs. The key concepts have been
                analyzed theoretically and empirically, whereby the three hypotheses have been
                tested to reveal the nature of the relationship between relevant constructs. In
                particular, all variables in the research model were measured on a multi-national
                sample of 162 SMEs operating in a single business sector, which contributed to the
                adequate comparability of the results. The measurement model was checked for
                reliability and coherence. At the same time, the resulting structural models have
                also been assessed through adequate statistical procedures, including the
                calculation of relevant model fit indices. All observed constructs were positively
                mutually correlated, with a statistical confidence level of 1 %, and all
                corresponding hypotheses have been empirically confirmed in this research.
                Therefore, the obtained findings of this study imply that the managerial factors
                have a statistically significant positive impact on digital business model maturity,
                which proves H1 and answers the research question. Specifically, both management
                education (H2) and management digital skills (H3) have exerted a positive influence
                on the maturity of the company's digital business model, which implies that one of
                the possible ways to improve company's digital business model maturity is by
                fostering targeted improvements in the relevant managerial education and their
                digital skills. While previous studies have focused on the adoption of technology,
                ability to innovate, organizational readiness, capacity to stimulate the development
                of business ecosystems, this study stressed the importance of managerial factors in
                achieving digital business model maturity. This empirical research aligns with
                previous papers, namely with the work of <xref ref-type="bibr" rid="r29">29</xref>,
                who pointed out that digital transformation efforts must be led from the top. In
                addition to those general findings, the research results indicate several potential
                improvement areas on a deeper level, including managers' education about digital
                business and technologies and managers' knowledge to lead a digital strategy and
                their actual participation in developing and implementing it. In that capacity, the
                results of this study show that managerial factors can be seen as the prerequisites
                for successful digital transformation and implementation of a digital business
                model. The obtained results further develop the scientific understanding of digital
                business model maturity and its relevant managerial factors. While previous research
                endeavors have frequently focused on a general notion of digital business models
                maturity, mainly pursuing a theoretical approach (e.g. <xref ref-type="bibr"
                    rid="r10">10</xref>, <xref ref-type="bibr" rid="r31">31</xref>), this paper goes a
                step further. It contributes with international empirical research, encompassing the
                companies from 42 different countries across 5 continents. Regarding the limitations
                of this research, there are several of them to be noted. On the one hand, the
                research has been performed within a single business sector, enabling internal
                comparability. Still, it could also be viewed as a limitation because some of the
                findings may not be applicable in the same way to other business sectors. On the
                other hand, there are some limitations to the survey methodology itself. In
                particular, the most notable issue has been related to the highly structured format
                of the research instrument, which did not allow for individual free-style comments
                by the respondents. To compensate for this limitation, some of the respondents sent
                additional thoughts and comments to the authors via e-mail or social networks, which
                is why it is recommended that further studies of this topic do include more space
                for such additional comments within the very research instrument. With all this in
                mind, this paper extends the body of knowledge in the field, contributing empirical
                evidence on achieving the appropriate level of digital business model maturity,
                which is important from both scientific and managerial viewpoints. The results of
                this study can be useful to other researchers to design their empirical studies in
                this field and seek to understand these constructs in other kinds of business
                settings, such as for large companies or specific business sectors of interest.
                Further research may involve comparative studies, seeking to observe and explain any
                systematic differences between industries or geographies or validate the research
                model shown here with in-depth case studies (such as those in <xref ref-type="bibr"
                    rid="r45">45</xref>) in specific industries. Researchers may also opt to explore
                the impact of other factors on digital business models maturity and the impact of
                the digital business model maturity on certain aspects of the company performance.
                The managerial implications of this paper are threefold. Firstly, it could help
                practitioners shed more light on the fast-evolving field of digital business models
                and understand the relevant managerial factors that may be a tool to improve the
                company's digital business model maturity. The ability of a company to shift to a
                digital business model proves to be one of the most important topics in adjusting
                businesses to the Covid-19 pandemic environment, and the results of this paper might
                provide useful guidance for practitioners and managers. Secondly, they may also
                choose to benchmark their own company by answering the questions provided in the
                measurement model, which could also be useful for identifying gaps and areas for
                future improvement in that particular company. Finally, this research may inspire
                the managerial community to explore different approaches and ideas and assist them
                in taking certain strategic and tactical decisions regarding the digital aspect of
                their operations. In conclusion, due to the highly intense uptake of digital
                business models, as an integral part of the new digital age, it is increasingly
                relevant to continue studying these phenomena from a scientific perspective, seeking
                to understand further their nature, potential impacts, and facets of possible
                implications. </p>
