  The study scrutinizes the connection between the big data characteristics and innovation performance in selected manufacturing firms in Ghana and the mediating role of the big data team in this relationship. This provides a new perspective to the ongoing debate on the big data innovation nexus globally. Using data from 43 accidentally selected manufacturing firms from Greater Accra in a structural equation model, the study confirms that big data characteristics positively influence innovation performance in manufacturing firms. However, velocity and volume are negatively associated with innovation performance in these firms. Finally, the sophistication and skill levels of the big data team positively mediate the connection amid big data characteristics and innovation performance. Therefore, management should prioritize the employment of a highly skilled big data team to benefit from all the characteristics of big data. Further, firms should consider the long-run big data analytics benefits over the initial cost of investment.

Introduction</title><p>Businesses compete for market position, survival, and growth through product development and process reengineering [<xref ref-type="bibr" rid="scirp.115446-ref1">1</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref2">2</xref>]. However, decisions regarding the specific type of product/service or processes to implement strategically depend on several factors [<xref ref-type="bibr" rid="scirp.115446-ref3">3</xref>]. Aside from the contribution of the internal and the external business environment to the decision-making process of businesses, big data has evolved into a critical organizational resource for innovation [<xref ref-type="bibr" rid="scirp.115446-ref4">4</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref5">5</xref>]. Big data involves a large collection of structured and unstructured data which requires relatively complex analytics [<xref ref-type="bibr" rid="scirp.115446-ref6">6</xref>]. Businesses irrespective of location, size, or Mundus Operandi generate volumes of data daily concerning the business operations. Accordingly, the literature suggests that big data could become significant to the decisions of the business if properly managed and analyzed [<xref ref-type="bibr" rid="scirp.115446-ref7">7</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref8">8</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref9">9</xref>]. Consequently, this has attracted research inquisition concerning the role of big data analytics in the innovation performance of businesses of all sizes [<xref ref-type="bibr" rid="scirp.115446-ref10">10</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref11">11</xref>]. While these studies find positive associations amid big data analytics and innovation performance, other studies suggest that the characteristics of big data (volume, velocity, variety, veracity, and value) and capabilities of the big data team could inhibit this positive association [<xref ref-type="bibr" rid="scirp.115446-ref7">7</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref12">12</xref>]. Thus, this creates a research gap requiring empirical inquisition to avoid policy imbalance.</p><p>Innovation performance revolves around the ability of a business to increase the effectiveness, significance, and functionalities of new products/services, processes, or procedures [<xref ref-type="bibr" rid="scirp.115446-ref13">13</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref14">14</xref>]. Therefore, businesses strive to invest in innovations capable of improving these aspects of the firm [<xref ref-type="bibr" rid="scirp.115446-ref15">15</xref>]. However, to meet these targets, innovations should be pursued through thorough environmental analysis, extensive market research, and big data analytics [<xref ref-type="bibr" rid="scirp.115446-ref8">8</xref>]. Consequently, the quality of human resources in an organization could affect the quality of information generated and the resultant innovation. Therefore, as earlier stated, the capabilities of the big data team in an organization become significant at this stage. However, existing studies by far on this phenomenon ignore big data teams’ role in the link between big data analytics and innovation performance. Therefore, this study fills this gap by examining the mediating role of the big data team in the link amid big data analytics and innovation performance. The study seeks answers to the questions, what is the relationship between the big data characteristics and innovation performance? And does the big data team mediate the relationship between big data characteristics and firm performance? The big data characteristics involve big data (volume, velocity, variety, veracity, and value). Innovation performance also focuses on product innovation performance.</p><p>The study focuses on manufacturing firms in Ghana because these groups of firms are constantly faced with the challenge of introducing new products, cost-cutting processes, and procedures to ensure sustainability. Further, this market is relatively saturated so customers seek superior products at relatively cheaper prices to maintain their loyalty to a specific brand. Therefore, to remain competitive in this saturated market, these firms must improve innovation performance. Employing survey data from 43 manufacturing firms in the Greater Accra region of Ghana and using structural equation model, the study reveals that big data analytics influences innovation performance in manufacturing firms. Further, the sophistication of the big data team mediates the link between big data analytics and innovation performance. Therefore, the study adds extensively to the existing literature on big data and innovation nexus.</p><p>Several studies examine the relationship between big data and the innovation performances of firms of all sizes. While some of the findings from these studies are synonymous with the current study, others contradict. <xref ref-type="table" rid="table1">Table 1</xref> provides a</p><table-wrap id="table1" ><label><xref ref-type="table" rid="table1">Table 1</xref></label><caption><title> Summary of state of the art</title></caption><table><tbody><thead><tr><th align="center" valign="middle" >Author</th><th align="center" valign="middle" >Focus</th><th align="center" valign="middle" >Method(s)</th><th align="center" valign="middle" >outcome</th></tr></thead><tr><td align="center" valign="middle" >Trabucchi &amp; Buganza [<xref ref-type="bibr" rid="scirp.115446-ref10">10</xref>] .</td><td align="center" valign="middle" >Data-driven innovation</td><td align="center" valign="middle" >Exploratory multiple case study analysis</td><td align="center" valign="middle" >Big data drives innovation in firms</td></tr><tr><td align="center" valign="middle" >Bresciani et al.

Trabucchi and Buganza [<xref ref-type="bibr" rid="scirp.115446-ref10">10</xref>] using multiple case studies confirms that big data analytics promotes positive firm innovation. Bresciani et al. [<xref ref-type="bibr" rid="scirp.115446-ref16">16</xref>] in a systematic review suggest that big data analytics and intentional firm collaboration drives firm innovation. This study combines all the elements of big data characteristics without differentiation. However, Babu et al. [<xref ref-type="bibr" rid="scirp.115446-ref11">11</xref>] also identify that the seven steps in data-driven innovation are significant to the innovation performance of a firm. Lerena et al. [<xref ref-type="bibr" rid="scirp.115446-ref17">17</xref>] found that there exist different levels of data mining in big data and thus these heterogenous levels could affect innovation. Again, Ghasemaghaei &amp; Calic [<xref ref-type="bibr" rid="scirp.115446-ref7">7</xref>] suggest that although other characteristics of big data are significant, velocity is more critical to innovation. These studies focus on the different characteristics of big data and the consequential effect on innovation. Per Wright et al. [<xref ref-type="bibr" rid="scirp.115446-ref8">8</xref>], big data could provide a clue to the innovation drive of a firm. Further, other studies all find a positive association between big data and innovation performance in different classes of businesses [<xref ref-type="bibr" rid="scirp.115446-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref9">9</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref12">12</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref18">18</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref19">19</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref20">20</xref>]. Thus, our study contributes to data by focusing on the different big data characteristics and the performance of manufacturing firms in Ghana by considering the mediating role of the big data team.</p><p><xref ref-type="fig" rid="fig1">Figure 1</xref> describes the connections amongst the variables.

This depicts the associations between big data characteristics, innovation performance, and big data team. Two research hypotheses are developed to verify the relationships between the variables. We expect the various big data characteristics to positively influence innovation performance in these SMEs. Further, although these characteristics are expected to influence innovation performance, we also propose that the strength of these relationships could be explained by the quality of the big data team in the SMEs.</p><p>Hypothesis H1.

Research Methodology</title><p>The study employs a descriptive research approach to gauge the association amid big data characteristics and innovation performance in the selected Ghanaian manufacturing firms. Manufacturing firms are preferred over service firms because of the need to differentiate products to satisfy the needs of customers. The study focuses mainly on manufacturing firms in the Greater Accra Region of Ghana. In all, there are dozens of such businesses, however, most of these businesses were unwilling to partake in the survey so the non-probability accidental sampling technique was employed to include firms that are willing. In all, 64 firms were included in the study as the sample. The study surveyed the chief executive officers of these firms. This is because they are considered individuals responsible for the overall direction of the firm. The data was collected using a survey questionnaire. First, questionnaires were piloted to eliminate errors and ambiguity. After, the survey instrument was edited to suit the purpose of the study. The overall data collection period lasted between May, 2021-August, 2021. <xref ref-type="table" rid="table2">Table 2</xref> provides details of the survey instrument design and the corresponding sources. The big data characteristics include velocity, volume, value, variety, and veracity [<xref ref-type="bibr" rid="scirp.115446-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref12">12</xref>].

Therefore, we employ the structural equation model (SEM) comparable to existing literature (Lozada et al.), [<xref ref-type="bibr" rid="scirp.115446-ref18">18</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref20">20</xref>] to estimate the association between big data characteristics (BDC), innovation performance (INP), and big data team (BDT). The model supports the estimation of multifaceted relations between one or more independent variables as well as one or more dependent variables. This statistical technique allows the assessment of multilevel regression models and is applied to testing research hypotheses with direct and indirect observations of one or more dependent and independent variables. The main reason for adopting this technique in this study is to help assess the relationship between the variables and validate the proposed causal models. Accordingly, BDC is the response variable (Y) while INP is an exogenous variable with BDT as the mediating variable. The model is presented hypothetically in a matrix form as:</p><p>[ y 1 ⋮ y p ] = ( 0 ⋯ β 1 p ⋮ ⋱ ⋮ β p 1 ⋯ 0 ) [ y 1 ⋮ y p ] + ( δ 11 ⋯ δ 1 q ⋮ ⋱ ⋮ δ p 1 ⋯ δ p q ) [ x 1 ⋮ x q ] + [ ε 1 ⋮ ε p ] (1)</p><p>In Summary, the matrix equation in Equation (1) is reformulated as:</p><p>Y = B Y + Γ X + ε (2)</p><p>where p symbolizes the regression equations to be assessed concurrently, p by p B square matrix encompasses the parameter coefficients of the regressors of Y variables on the other Y variables with the 0 diagonal values denoting that a variable cannot influence itself. Furthermore, the p by q Γ matrix contains coefficients of the Y’s on X’s whereas ε is a p by 1 vector consisting of residual terms. Grounded on the theoretical model specification, reasoning can be made that a number of regression Equations (3) are to be estimated to gauge the causal effects amid the variables employed in the study as indicated in Equations (3a) and (3b). First, Equation (3a) considers the relationship between the big data teams (BDC) and innovation performance (INP) in the SMEs as previously examined by key studies [<xref ref-type="bibr" rid="scirp.115446-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref17">17</xref>].</p><p>BDC i = β 0 + β a INP + ε i (3a)</p><p>Next, given the critical role of big data teams in big data analytics, Equation (3b) considers the mediating role of big data team (BDT) in the relationship between big data characteristics and innovation performance as previously tested in other studies [<xref ref-type="bibr" rid="scirp.115446-ref12">12</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref20">20</xref>].</p><p>BDC i = β 0 + β b BDT ∗ + β a INP + ε i (3b)</p></sec><sec id="s3"><title>3. Empirical Estimation</title><sec id="s3_1"><title>3.1. Multicollinearity Test</title><p>Before estimating the model, it is important to examine if the variables under consideration have no issues of collinearity, Therefore, following the study of Cephasetal., [<xref ref-type="bibr" rid="scirp.115446-ref21">21</xref>], we review the probability of multicollinearity between the variables using the variance inflation factor (VIF). Given the acceptance or rejection of the null hypothesis benchmark, values of the VIF must not exceed 10.00. These values are automatically estimated with the SmartPLS. Consequently, given the output in <xref ref-type="table" rid="table3">Table 3</xref>, the null hypothesis of the existence of multicollinearity is rejected because all the values reported are within 10.00 bound. Thus, we can proceed to estimate the final structural equation model.</p></sec><sec id="s3_2"><title>3.2. Construct’s Reliability and Validity Tests</title><p>The study employs a sequence of tests to examine the reliability and validity of the study constructs. See <xref ref-type="table" rid="table4">Table 4</xref> for details of the test results. These tests are necessary to satisfy the conditions for the estimation of the final structural model depicted in <xref ref-type="fig" rid="fig1">Figure 1</xref>. Accordingly, the Herman Single Factor, B-S test, KMO and Bartlett’s test, the Cronbach alpha, factor loadings, and the Eigen-value are employed. Per the Herman Single factor test via the principal axis factoring (PAF), the value of 35.43% indicates that a single factor is an issue in the study because the value is less than 50%.

Discussion</title><p>The study reconnoiters the association amid big data characteristics and innovation performance in manufacturing firms in Ghana. Further, it examines the mediating role of the big data team in the association between big data characteristics and innovation performance.</p><p>Big data characteristics positively influence innovation performance in manufacturing firms. This is consistent with existing studies [<xref ref-type="bibr" rid="scirp.115446-ref10">10</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref11">11</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref16">16</xref>] to indicate the significance of big data analytics in the innovation activities of firms of all sizes. Management should invest in advanced data analytics software which provides cutting-edge analytics to support the innovation agenda of the firm. This also challenges firms not investing enough into big data analytics in Ghana to consider the sustainable significance of big data analytics over the initial cost of investment. Further, aside from big data analytics, management should endeavor to engage other parties like customers and other firms as suggested by Bresciani et al. [<xref ref-type="bibr" rid="scirp.115446-ref16">16</xref>]. This is because these sources of innovation also contribute a rich source of data that may not be made available to a firm through only big data analytics.</p><p>Value, variety, and veracity are positively linked with innovation performance in the manufacturing firms while velocity and volume are negatively linked with the innovation performance of the firms. While it is expected that all these characteristics positively affect the innovation performance of firms, other studies [<xref ref-type="bibr" rid="scirp.115446-ref6">6</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref12">12</xref>] also identify differences in the contribution of these characteristics to innovation performance. This difference could be explained by the sources of the data as well as the sophistication of the big data team. Therefore, firms should expand the sources of big data by including both internal and external sources of data. Further, the firms should employ big data teams with the necessary skills to exploit all the characteristics of big data to improve innovation performance. This is because all these five big data characteristics have significant contributions to innovation if properly harnessed.</p><p>Finally, big data team positively mediates the association between big data characteristics and innovation performance in manufacturing firms. This is coherent with the outcome of existing studies [<xref ref-type="bibr" rid="scirp.115446-ref8">8</xref>] [<xref ref-type="bibr" rid="scirp.115446-ref19">19</xref>] to show that the qualification and sophistication of the big data team in a firm has a significant role in the innovation performance of firms. Theoretically, the absence of a big data team means a firm cannot utilize big data analytics in decision-making. However, the skill level and sophistication of the big data team would determine the extent of analytics performed to support the decision of the firm. Therefore, the management of firms should strategically recruit individuals with the prerequisite knowledge in big data analytics. Again, management should design training and development programs to constantly update the knowledge and skill levels of the big data team to promote industry best practices.</p></sec><sec id="s5"><title>5. Conclusions</title><p>The study examines the model (big data characteristics, innovation performance, and big data team) after performing multicollinearity checks, reliability tests, and validity tests to ensure the robustness of the results. Therefore, the conclusion of the study is grounded on the robust outcome of the model.</p><p>The study confirms that big data characteristics positively influence innovation performance in manufacturing firms in Ghana. This is because the decision-making process of firms is supported by rich data/information availability. Therefore, big data analytics provides a good source of data for these businesses. Consequently, this challenges firms in Ghana to invest in big data analytics to provide real-time data for decision-making quality. Firms looking to compete in today’s competitive business environment cannot ignore the significance of big data and thus should consider big data analytics in decision making irrespective of the initial estimated cost involved.</p><p>Further, the study establishes that value, variety, and veracity are positively connected with innovation performance in manufacturing firms. On the other hand, velocity and volume are negatively connected with the innovation performance of the firms. While all the five big data characteristics are significant to the quality of analytics generated, this outcome could be explained by the skill level or the sophistication level of the big data team available in the firms. Therefore, because the best of big data analytics is achieved through these five distinct characteristics, the management of these firms should institute strategic human resource plans to recruit and select highly skilled big data teams to achieve optimum data analytics results for improved innovation performance.</p><p>Finally, big data team positively mediates the connection between big data characteristics and innovation performance in manufacturing firms. While the relationship between big data and innovation is established, big data team sophistication and skill level provide the needed missing piece of the jigsaw puzzle. This suggests that management should prioritize the quality of the big data team if they desire to achieve optimum results. In Ghana, most businesses are small or medium in size and thus financial constraints could inhibit their decisions to invest in big data analytics. However, in the long run, these businesses would benefit from big data analytics if investments are made strategically.</p></sec><sec id="s6"><title>6. Limitations and Recommendations for Future Studies</title><p>The study adds to the existing literature on the linkage between big data analytics and innovation performance in businesses. Although this is timely, it has a few limitations that could be improved in future studies. First, the study focuses only on the capital city of Ghana and thus excludes businesses in the rural areas. Future studies should consider this class of businesses to examine the difference in business location. Finally, the study focuses on manufacturing firms using the structural equation model and thus ignores other classes of businesses. Future studies should consider other classes of businesses with different estimation methods.</p></sec><sec id="s7"><title>Conflicts of Interest</title><p>The authors declare no conflicts of interest.</p></sec><sec id="s8"><title>Cite this paper</title><p>Otchere, S.K., Nyamewaa, E.B. and Hammond, F.
