The underlying factors of a successful organisational digital transformation

non-IT leaders hold contrasting views on these factors.


Introduction
Owing to the rapid rate of digital change, organisations are compelled to increase the pace of their digital transformation by revising and overhauling outdated offerings and processes (Westerman et al. 2012).Few organisations will be spared from the disruptive impact of ever-increasing competition brought about by technology advancement and the evolution of business models (Fitzgerald et al. 2013).To navigate the complexity associated with an organisation's digital transformation, many leaders find themselves overwhelmed as to how they should orient their digital transformation strategy prior to embarking on such an initiative (Kane et al. 2015(Kane et al. , 2016)).Unpacking the key underlying factors affecting the organisational digital transformation (ODT) can greatly assist the leaders to streamline their investments, develop a comprehensive digitisation roadmap and explore new digitalisation opportunities (Abolhassan 2017;Matt, Hess & Benlian 2015;Westerman et al. 2011).
There remains no consensus in the literature on a definition of ODT.Westerman et al. (2011) consider digital transformation as the use of technology to radically improve the performance of enterprises.In contrast, Fitzgerald et al. (2013) regard digital transformation as the use of new digital technologies (social media, mobile, analytics or embedded devices) to enable major business improvements (such as enhancing customer experience, streamlining operations or creating new business models).These interpretations of ODT represent a narrow view, with emphasis on the 'use of digital technologies'.In contrast, Kane et al. (2015) propose that the success of an ODT initiative does not stem from the appropriate use of technology only but is more dependent upon having a clear and effective digital strategy endorsed by leaders.Matt et al. (2015) similarly advocate the importance of taking on a business-centric perspective to view ODT Background: Organisational digital transformation (ODT) is a field of growing interest in practice and academia.Further, a disparity between how information technology (IT) leaders and non-IT leaders perceive the factors leading to successful ODT initiatives has been cited.A set of empirically tested ODT assessment instruments will enhance leaders' decision-making when implementing ODT initiatives.

and describe ODT as the strategies that 'focus on the transformation of products, processes, and organisational aspects owing to new technologies'.For the purposes of this research, we have adopted the views proposed by Kane et al. (2015) and Matt et al. (2015) owing to the increasing support of literature (Berman 2012;Desmet et al. 2015;Kane et al. 2016;Oswal & Kleinemeier 2017;Wade 2015).We define ODT as the strategic interventions that enhance the organisational digital capability with the purpose of improving the organisation's processes, products, services and business models to satisfy their customers.

Underlying factors affecting the success of organisational digital transformation
A range of underlying factors affecting the overall success of ODT have been proposed by various scholars.Several recent studies suggest organisational structure and culture are significant factors of ODT (Kane et al. 2016;Wade 2015;Westerman et al. 2014).One study found that customer centricity, in the form of improving the customer experience, customer service and customer value proposition, is the critical factor driving ODT (Berman 2012).Corporate innovation, customer centricity, business models, governance and technology-related aspects have also been posited as the building blocks for achieving digital transformation (Desmet et al. 2015;Oswal & Kleinemeier 2017).
Table 1 presents 16 major factors identified from extant literature on ODT.However, many of these propositions lack the support of empirical evidence, despite having been vigorously debated.MIT Sloan Management Review and Deloitte addressed the lack of consensus with a global study of 4800 executives, managers and analysts in 2014 (Kane et al. 2015).However, the results added to the lack of consensus with their unearthing of potential factors not identified or studied elsewhere, such as the utilisation of innovative financing models and creation of a supportive collaboration with suppliers and customers.We believe that an ODT initiative is likely to fail when organisations do not establish the appropriate funding mechanisms and acquire the key resources to support the initiative.
In short, the total number of empirical studies on the underlying success factors of ODT is limited; extant studies do not exhibit uniformity in the factors identified; and a number of the factors identified in the literature, such as strategic procurement and innovative funding models, have received insufficient examination and explanation to serve as a foundation for development of an ODT assessment instrument.

Information technology and non-information technology leaders' perceptions
Research suggests that leaders' contrasting interpretations of ODT are often associated with their different professional  ODT, organisational digital transformation capacities (Westerman et al. 2014).Gerth and Peppard (2016) note that the failure of ODT initiatives is often blamed on IT leaders who lack a broader understanding of the key factors affecting such major undertakings.Singh and Hess (2017) claim that senior leaders in charge of the IT divisions are often pure technologists who focus more on the technology than the needs of the customers; while senior leaders responsible for non-IT divisions act as business strategists, and treat technology as a means to a greater end.An IT executive may understand digital transformation as an adoption of cloud technologies, while a marketing leader may consider it a move towards e-commerce or social media, and a financial leader may interpret it as a novel payment platform or data analytics (Westerman et al. 2011).Such misalignment diminishes success rates of ODT initiatives.

Proposed
In contrast, a study by the Economist Intelligence Unit (2016) suggests that IT and non-IT executives hold similar understandings of the role of ODT initiatives and the factors that drive their success.Thus, while there is a strand of research suggesting contrasting stances between IT and non-IT leaders on the factors underlying successful ODT initiatives, this is far from an established phenomenon.This lack of consensus in the literature informs the second aim of this study to test the hypothesis that these two groups view these factors differently.

Research methodology
This article set out to determine the underlying factors of success for ODT initiatives and, secondarily, to test the hypothesis that IT and non-IT leaders perceive these differently.

Data collection
A prescreening process was conducted to ensure each invited survey participant met the selection criteria before taking part in this research.The criteria applied were as follows: • Participants must work for a large organisation (defined as 5000 employees or more) within the private sector.This criterion was to prevent this research from being diluted by comparing the dynamics within large enterprises against those from small and medium-sized enterprises or public agencies.• Participants' employer business must comprise a strong business-to-consumer portfolio.This was to ensure the capacity to test ODT success factors relating to customer centricity.• Participants' organisations must have previously undergone a process that meets the definition of ODT as defined above.• The headquarters of each participant's firm must be located within the country (South Africa).This stipulation ensured that each participant's organisation had the autonomy to drive its own ODT agenda, independent of a foreign head office.
• Participants must each hold a decision-making role in a unit whose success could be affected by digital trends.This limitation ensured targeting only senior leaders with a vested interest in ODT.
Sixty companies and two hundred fifty potential participants were preselected to participate in the survey.Only 136 of the potential respondents were invited to complete the survey based on the data collection criteria described.

Establishing the underlying factors of successful organisational digital transformation initiatives
A quantitative research methodology was adopted to identify the factors underlying successful ODT initiatives.
To construct the list of potentially significant underlying success factors for ODT initiatives and test their validity, this study adapted Benson and Clark's (1982) instrument development process.This required the identification of the relevant literature and a subsequent analysis to identify factors explicitly or implicitly unearthed in these studies.This process discerned 36 factors posted by the academic literature as significant determinants of the success of an ODT initiative.These formed the list of potential underlying factors to be tested with a sevenpoint Likert scale questionnaire.On the questionnaire, the participants scored the importance of 36 items (1 = least important and 7 = most important).This questionnaire is reproduced in Table 2.
An exploratory factor analysis (EFA) was carried out on the collected research data as it is well-suited for developing a new instrument or scale (Fabrigar et al. 1999;Yong & Pearce 2013).The principal axis factoring (PAF) method was deployed to identify the underlying structure of the ODT assessment instrument.The PAF method has been recommended for recovering weak factors when sample sizes are small and when the data severely violates the assumption of multivariate normality (Creswell 2012;De Winter & Dodou 2012;Fabrigar et al. 1999).Principal axis factoring zeroes in on the shared (common) variance between the observed variables and explains the latent factors underlying the data (Fabrigar et al. 1999).The face value validity and content validity of the ODT assessment instrument was investigated.

Comparing information technology and noninformation technology leaders' perceptions
The Cronbach's alpha of each factor was analysed to establish the internal reliability.Cronbach's alpha measures the consistency of responses across all questions or subgroups of questions and is the most frequently used method for testing internal consistency (Saunders, Thornhill & Lewis 2015).
After the key dimensions of factors were identified as the result of the above procedures, this study investigated whether IT and non-IT senior leaders hold different perceptions on the underlying factors of successful ODT initiatives.For each dimension of factors uncovered, the http://www.sajim.co.zaOpen Access

Kruskal-Wallis H test was conducted based on the following hypotheses:
H 0 : There is no difference in the way that IT and non-IT managers regard the importance of that particular dimension of underlying factors.
H 1 : There is a difference in the way that IT and non-IT managers regard the importance of that particular dimension of underlying factors.
The exact hypotheses are listed in the following section.

Results
The response rate was 69.85% (n = 95) and the respondents came from 34 organisations across 9 different industries (Table 2 and 3).The 95 respondents were made up of 45 IT leaders and 50 non-IT leaders.This sample size met the recommended minimum subject-to-variables ratio of 2:1 for conducting EFA with small sample sizes (Barrett & Kline 1981;De Winter, Dodou & Wieringa 2009).

Underlying success factors of organisational digital transformation initiatives
The calculated Mahalanobis distances (MDs) were used to identify multivariate outliers based on a chi-square test, assessed using a p-value of p < 0.001.Four cases (n = 95) were identified as outliers because they had maximum MDs (56.220;51.079;50.341;47.076;42.607)larger than their critical chisquare values (df = 15) assessed at a critical alpha of 0.001.The identified outliers were not deleted because PAF does not require the multivariate normal assumption (Wang & Du 2000).
The Shapiro-Wilk test (p > 0.05) used to test for multivariate normality indicated that all 15 observed variables had a p-value (Sig.= 0.000) that was below 0.05.Therefore, the null hypothesis (p > 0.05) stating that data is normally distributed was rejected.As such, we concluded that the multivariate normality assumption was violated.Fabrigar et al. (1999) recommend principal factoring methods if the assumption of multivariate normality is severely violated.Therefore, the PAF method was used to conduct EFA.Applying Norman (2010), parametric statistics (i.e.EFA) can safely be used with a Likert scale, with non-normal distributions, with small sample sizes and with unequal variances.
The linearity assumption was tested by inspecting the correlation matrix for correlation coefficients greater than 0.3.The correlation matrix indicated that all variables had linear relationships (correlation coefficient > 0.3) with one or more variables.As such, the required linearity assumption  for conducting factor analysis was satisfied.To test for multicollinearity, we ran SPSS v24 bivariate correlation analysis to identify variables with high correlations (>0.9) that could cause multicollinearity.SPSS v24 was used for linear regression (collinearity diagnostic) to identify multicollinearity by assessing the variance inflation factor of all 36 variables.The result confirmed that the multicollinearity assumption was satisfied.
The Kaiser-Meyer-Olkin measure (KMO) of sampling adequacy and Bartlett's test of sphericity were used to examine the factorability assumption.The measures of sampling adequacy (KMO and Bartlett's test) indicated that the factorability assumption was satisfied.The KMO was more than 0.6 (KMO = 0.782) and the Bartlett's test of sphericity was significant (X 2 [630] = 2077.683,p < 0.001), indicating a factorable correlation matrix.The initial solution suggested a nine-factor solution based on eigenvalues >1.0.The KMO was more than 0.6 (KMO = 0.732) and Bartlett's test of sphericity was significant (X 2 [630] = 2077.683,p < 0.001), indicating a factorable correlation matrix.Based on the measures of the sampling adequacy results, it was concluded that the factorability assumption was satisfied (Table 4).
Initially, 36 items were constructed as the latent variables.
The final PAF varimax rotation solution extracted four factors and a total of 15 items.Table 5 provides the SPSS output of the rotated factor matrix, which demonstrates adequate convergent validity for all four factors because all loadings were above the minimum threshold of 0.4.These four factors explained 63.9% of the total variance within the observed data.The factors were: customer centricity (28.7%), governance (13.1%), innovation (11.6%) and resource attainment (10.5%).All four factors had a Cronbach's alpha more than 0.7, which is considered an indicator of good internal consistency (Zikmund et al. 2010).The Cronbach's alpha values for customer centricity, governance, innovation and resource attainment were 0.840, 0.779, 0.799 and 0.864, respectively.Content validity and face validity of the ODT assessment instrument was established based on the literature presented in Table 1.

Information technology and non-information technology leaders' perceptions
As the EFA analysis revealed four underlying factors of ODT success, the hypotheses are proposed as follows: • Hypothesis 1 -H1 0 : There is no difference in the way that IT and non-IT leaders perceive customer centricity as an underlying success factor of ODT.• Hypothesis 2 -H2 0 : There is no difference in the way that IT and non-IT leaders perceive governance as an underlying success factor of ODT.• Hypothesis 3 -H3 0 : There is no difference in the way that IT and non-IT leaders perceive innovation as an underlying success factor of ODT.• Hypothesis 4 -H4 0 : There is no difference in the way that IT and non-IT leaders perceive resource attainment as an underlying success factor of ODT.
The results of the Kruskal-Wallis H test (p > 0.05) showed that the median scores of the four factors were not statistically significantly different between IT leaders (n = 45) and non-IT leaders (n = 50).Therefore, the null hypothesis (H0) for each of the four factors, was retained, suggesting that there is no difference in the way that IT leaders and non-IT leaders perceive underlying success factors of ODT initiatives.
In addition, the median scores for all four factors were not statistically significantly different between IT leaders and non-IT leaders (customer centricity: X 2 (1) = 0.406, p = 0.521; governance: X 2 (1) = 0.378, p = 0.539; innovation: X 2 (1) = 1.559, p = 0.212; resource attainment: X 2 (1) = 0.125, p = 0.723).Therefore, the null hypothesis (H0) for all four factors was retained in support of the overall research hypothesis (Hypothesis 1).There is no difference in the way that IT managers and non-IT managers perceive customer centricity as the most important dimension for internal ODT.The hypothesis test summary with all p-values can be viewed in Table 6.

Towards an organisational digital transformation assessment instrument
According to Boström and Celik (2017), many assessment instruments in academic literature are developed without sufficient research and methodological rigour to robustly verify the validity and reliability of the instrument.In contrast, this research sought to empirically establish the reliability, face value validity, content validity, and convergent and divergent validity of underlying success factors for ODT initiatives previously suggested in the literature.By conducting statistical tests to determine the relationship among items (Creswell 2012), the validity based on internal structure was established.Principal axis factoring analysis confirmed the existence of four dimensions of underlying factors of a successful ODT initiative.These dimensions are (1) customer centricity, (2) governance, (3) innovation and ( 4) resource attainment.The findings are congruent with the arguments made by Kane et al. (2015) that the driver of ODT is strategy, not technology.

Customer centricity
Customer centricity is the proclivity of an organisation to focus on the interdisciplinary and organisational challenges associated with successfully designing and managing the customer experience (Lemon & Verhoef 2016).Despite that, the relationship between ODT and user co-creations leading to process refinement have been discussed extensively (Berman 2012;Desmet et al. 2015;Sia, Soh & Weill 2016;Wade 2015;Westerman et al. 2014) and a number of researchers have argued customer centricity to be an underlying success factor in ODT (Berman 2012;Desmet et al. 2015;Sebastian et al. 2017;Sia et al. 2016;Wade 2015;Westerman et al. 2014), the empirical studies on this topic remain scarce.Our findings suggest that this dimension includes the following factors: (1) a customer-centred approach in designing offerings (Q6); (2) mechanisms to keep abreast with changing customer needs (Q1); (3) process digitisation and re-engineering (Q14); (4) prioritisation of digital projects (Q15); and ( 5) experimentation with new technologies to meet customer needs (Q24).
The findings of this study revealed that the surveyed executives believe that organisations ought to adopt a usercentric approach when designing their offerings (Q6).
Establishing effective mechanisms to keep abreast with changing customer needs is thus an imperative (Q1).However, revamping the digital capability alone will not lead to the desired impact unless the endeavour is complemented by refined processes (Kane et al. 2016).The participants further endorsed the importance of process reengineering (Q14) and prioritisation of digital projects (Q15).
The survey also uncovered that the overall success of an ODT initiative can be affected by an organisation's ability to experiment with new technology to meet customers' needs (Q24).This finding concurs with research that finds that a firm's approach and capability to explore and exploit new digital technologies is an important success factor for ODT (Hess et al. 2016).

Governance
This dimension describes the guiding policies, decision structures, roles and responsibilities used to coordinate and steer the organisation's ODT initiatives (Westerman et al. 2012).In light of the wide-reaching repercussions of transforming the digital modus operandi and strategic intent

http://www.sajim.co.zaOpen Access of the organisation, effective governance has been deemed by some researchers as a critical lever for organisations to drive successful digital transformation (Boström & Celik 2017;Westerman et al. 2012Westerman et al. , 2014)).This study found sufficient empirical evidence to support governance as a critical factor in driving the success of ODT.In particular, the findings suggest that leaders should ensure the following three factors are effectively addressed: (1) clearly defined monitoring and evaluation (M&E) criteria and mechanisms (Q21); (2) security systems, standards and practices used to secure data (Q20); and (3) guiding policies and decision-making to steer the ODT initiatives (Q19).
Without defining these M&E guidelines clearly and strategically, it will be difficult for leaders to keep abreast with the progress of the transformation process.It will also be harder for leaders to benchmark the progress against the business environment and competitors.Given that the business landscape today can change rapidly and disruptively, more scholarly attention should be placed on how leaders can ensure the M&E proposed at the outset can remain robust and relevant throughout a transformation.
'Shadow IT' is a term often used to describe information technology systems and solutions built and used inside organisations without explicit organisational approval (Silic & Back 2014).This poses severe threats of duplication of resources, wasted investment, inconsistency of business logics, security breaches and data loss or leaks.Failure to achieve effective governance can encourage different divisions within an organisation to develop their own workaround tactics, leading to the rise of shadow IT (Silic & Back 2014).

Innovation
Innovation describes an organisation's ability to develop and implement new ideas (Svahn et al. 2017).With the rapid adoption of digitally enabled business models and smarter technology, consumers are increasingly favouring companies that provide innovative digital offerings (Sebastian et al. 2017;Wade 2015).This study validates innovation -both in the form of culture and practice -as an underlying success factor of ODT initiatives.Within the category of innovation, this study finds the following individual factors significant to successful ODT initiatives: (1) establishing an effective innovation throughput mechanism (Q31); (2) exploring new digital business models (Q32); (3) instituting a dedicated innovation function (Q33); and (4) cultivating a helpful transformational culture (Q9).These findings are in line with previous studies (Berman 2012;Oswald & Kleinemeier 2017;Westerman et al. 2011), which assert that innovation, in both organisational practices and culture, affect the overall success of ODT.
In a recent study, Oswald and Kleinemeier (2017) linked innovation with ODT by developing a digital innovation and transformation framework.An organisation's capability to respond to new market opportunities in a timely fashion with innovative offerings is considered a critical advantage in today's business environment (Sebastian et al. 2017;Svahn et al. 2017).Our study concurred with these findings and suggested that organisations must have an effective mechanism to encourage innovation throughput (Q31) and to explore new digital business models (Q32).Considering that launching new innovative offerings and adopting new business models typically requires some level of intraorganisational collaboration and, at times, overhauling the traditional mode of operating, the importance of instituting a dedicated innovation function has been advocated (Hess et al. 2016).Our research concurred with this suggestion.In addition, the findings of our research also revealed the relevance of culture and further conformed with scholars who previously attributed the success of ODT initiatives in part to the innovative culture of the organisation (Boström & Celik 2017;Desmet et al. 2015;Kane et al. 2015;Matt et al. 2015;Oswald & Kleinemeier 2017;Sia et al. 2016;Singh & Hess 2017;Wade 2015;Westerman et al. 2014).

Resource attainment
The final dimension of success factors identified by this research describes the organisation's ability to acquire resources in the form of funding, infrastructure, expertise and knowledge through partnership.Kane et al. (2016) find that 32% of digitally transformed companies establish effective external relationships or partnerships.We posit that these partnerships, both internal and external, enable the organisation to create viable funding models and financing mechanisms, aiding the ODT process.Considering that financial resources are crucial when organisations are pursuing ODT (Matt et al. 2015), especially in light of intense competition inside organisations for funding of other initiatives, organisations need to find creative funding mechanisms and partnership strategies to support their ODT initiatives (Hess et al. 2016;Westerman et al. 2014).
This study finds the following factors relevant to leaders as success factors of ODT: (1) innovative financing models and (2) creative partnerships with suppliers and procurement strategies.Even though collaboration effectiveness and agility in buyer-supplier relationships (Hesping & Schiele 2015;Narayanan, Narasimhan & Schoenherr 2015) as well as the procurement strategy selected (Ateş, Van Raaij & Wynstra 2018) have been proposed as some of the key factors affecting an organisation's transformation performance, limited studies to date have been dedicated to how they affect the overall success of an ODT initiative.

Statistically insignificant factors
The study deliberately tested various technology-related factors, such as multichannel or omni-channel operations (Q13); platforms (Q26); integration of new systems with old IT legacy systems (Q22); and scaling of infrastructure on demand (Q23) for their relevance to the success of ODT.These factors were rejected by the survey participants.These findings are in accordance with the argument made by Kane et al. (2015) that the power of a digital transformation strategy lies in its scope and objectives rather than the technology.Even though scenario planning (Q2) and datadriven decision-making (Q3) were also excluded as factors, they may be better fitted with the overall strategy development process than with the ODT process.
Participant responses in this study refute the significance of aligning the strategies of different units (Q4) and embedding IT strategy in divisional strategies (Q5) as key underlying factors for successful ODT.Despite scholars having posited the importance of business-IT strategy alignment (Hess et al. 2016;Matt et al. 2015;Sia et al. 2016), whether various divisional strategies can achieve alignment should not greatly impact the outcome of an ODT initiative.In addition, it is the divisional strategies that shape the overall IT strategy.
Organisational IT strategy should be aligned to the needs of the business divisions but not necessarily embedded in the divisional strategies.
Despite some evidence that 'senior leadership must really understand the power of digital technologies' for successful ODT (Kane et al. 2015), our research demonstrates that leaders' own technology awareness (Q7) is not a significant factor.finding is not surprising, given that the leader's main responsibility is to set the strategic direction and that he or she can rely on technically competent staff to advise and drive the ODT process from that perspective.The potential reciprocity of digital capability and business strategy is an interesting topic for future study.
We further interpret the failure of silo prevention (Q12) and the coherency of organisational politics and the decentralisation of authority (Q8) showing up as significant factors of successful ODT as an indication that as long as leaders can set the direction firmly and hold people accountable, an ODT initiative does not need to address or control these factors intentionally.
Changing organisational structure (Q10) is another potential factor shown not to be statistically significant.Seeing that researchers have suggested that there are advantages and disadvantages to altering the existing corporate structure to increase the impact of ODT initiatives (Hess et al. 2016), the finding is not a surprising one.Several other change-related factors such as coordinating the portfolio of digital transformation initiatives (Q16), having a change campaign (Q17), establishing the engagement model with the rest of the organisation and external customers (Q27) and instituting urgency and efficiency through agile methodologies (Q18) were rejected as factors of a successful ODT.Further qualitative studies could be conducted to identify the most optimal change management mechanism to accompany ODT initiatives.
The involvement of external start-ups (Q25) may not always be necessary as some companies can rely on their internal resource and expertise to overcome ODT-related hurdles.
This research further suggests that to launch multilevel skills development (Q28), reshape employee key performance indicators (KPIs) (Q29) and implement rewards and recognition (Q30) may not be as critical as other factors identified.Scholars have suggested that outsourcing critical skills to increase organisational flexibility has become a common practice in recent years (Berman 2012).Our findings on the impact of KPIs, rewards and recognition towards ODT success contradict the recent suggestions made by Kontić and Vidicki (2018).However, Kontić and Vidicki did not empirically test these items despite the objective of their publication being to formulate a measurement tool for digital transformation.We therefore propose that further studies on these topics should be carried out.

Conclusion
In order to assist organisations to make effective investments in their pursuit of digital transformation, this article presented one of the few empirical studies on ODT.Postulates of key internal ODT factors of success from other studies have been theoretical in nature and lacked the necessary empirical evidence to reach conclusive inferences.This study identified underlying success factors of ODT initiatives suggested in extant literature.These were tested statistically, revealing four categories of significant factors.These are: (1) customer centricity, (2) governance, (3) innovation and (4) resource attainment.It was also shown through statistical analysis that IT and non-IT leaders do not substantially differ in their understanding of what these factors are.
Scholars and practitioners, possibly linking with other disciplines of management research (such as industrial sociology, digital road-mapping and agile methodology) can make use of this study to develop ODT assessment instruments, based on the underlying success factors identified in this article.As the factors of interest can be related to other constructs, future studies should also evaluate the nomological validity.
To succeed in digital transformation, big enterprises must continually keep abreast with changing customer needs and be highly disciplined in adopting user-centred approaches when designing their offerings.It is therefore imperative for leaders to create the audacious vision, strategy, process, divisions and culture that can encourage their employees to innovate and experiment with new technologies and business models.As no two organisations experience the same challenges, the M&E criteria and mechanisms, as well as the guiding policies and decision structures to steer the ODT initiatives, must be thoroughly deliberated and contextualised.Taking such concerted efforts prior to embarking on the ODT journey will permit employees to prioritise the digital projects, create multilevel partnerships and explore innovative financing models and procurement strategies that can best address the unique challenges of the organisation.While ODT brings forth unmatched opportunities for growth and value creation, there will always be risks involved.Therefore, leaders must also purposefully derive the security systems, standards and practices to prevent and mitigate risks associated with refining the processes and revamping the infrastructure.
McGrath et al. ( 2016) posit that leaders must establish a clear way forward in three areas: the 'why', 'what' and 'how' of the digital strategy.Answers to these questions will have far-reaching implications for management and their organisations.Implications for management relate to some of the critical questions that managers need to ask and answer when pursuing ODT.The findings of this research will be helpful to leaders by prompting strategic questions such as: What constitutes effective ODT governance?What value will an ODT initiative bring to customers?How will the organisation fund an ODT initiative?With whom should an organisation partner or collaborate with, and how should this be done, to achieve effective ODT?
Limitation and suggestions for future research Pohlmann (2004) suggests that factor structures are more stable when they are founded on large samples.The small sample size (n = 95) was the main limitation of this research; however, the PAF method was chosen specifically for its ability to recover weak factors when EFA is conducted with small sample sizes (De Winter & Dodou 2012).It is important to note that even with large sample sizes, EFA is considered to be an error-prone procedure (Costello & Osborne 2005).This research makes an inductive inference about the important determinants of the ODT and the field will benefit from future research to test the objectivity of this research.Confirmatory factor analysis can be used to confirm or reject the factor structure postulated in this research (Hurley et al. 1997), and future research can be conducted to unpack each construct identified in this research.Primarily, this study ought to serve as a foundation for later researchers for the establishment of an ODT assessment instrument, thus building on the critical success factors identified in this study.
