Abstract

:
Big Data (BD) has emerged as a pivotal tool for small and medium-sized enterprises (SMEs), offering substantial benefits in enhancing business performance and growth. This review investigates the impact of BD on SMEs, specifically focusing on business improvement, economic performance, and revenue growth. The objective of this systematic review is to evaluate the drivers and barriers of BD adoption in SMEs and assess its overall impact on operational efficiency and business outcomes. A comprehensive systematic review of 93 research papers published between 2014 and 2024 was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) framework. The methodology included detailed analysis of research approaches, addressing biases and gaps in the literature. BD adoption in SMEs led to significant improvements in operational efficiency, revenue generation, and competitiveness. However, the studies reveal persistent challenges, such as limited financial resources and technical expertise. The review identified a reporting bias, with 47% of studies using quantitative methods, 28% employing case studies, and mixed-method and qualitative studies underrepresented (22% and 17%, respectively). This imbalance highlights a potential overreliance on quantitative approaches, which may limit the depth of insights gained. While BD offers considerable potential for driving innovation and enhancing competitiveness in SMEs, addressing the current methodological biases and resource-related barriers is crucial to fully harness its benefits. Future research should focus on diverse approaches to provide a holistic understanding of BD’s impact on SMEs.

1. Introduction

Data have become a fundamental asset, shaping how businesses operate and strategize globally. The rise of digital technologies has triggered an immense surge in the amount of data generated across different platforms, such as social media, online shopping, and various digital tools. This phenomenon, known as Big Data, offers businesses extraordinary opportunities to gain insights into their internal processes, customer behaviors, and the broader market landscape [1]. For small and medium-sized enterprises (SMEs), which are crucial for economic development and innovation, the ability to harness Big Data is especially important. By adopting Big Data, SMEs can convert large datasets into practical intelligence, enabling them to refine business strategies, improve marketing effectiveness, boost competitiveness, and enhance overall performance. However, effectively utilizing Big Data is not without challenges, particularly for smaller companies that may lack resources and expertise [2,3,4].
Despite the clear advantages of data analytics, its adoption among SMEs remains lower than expected, especially when compared to larger organizations that are more actively embracing Big Data for decision-making and performance optimization. Several factors contribute to this slow adoption [5,6,7]. Financial limitations pose a major hurdle, as the costs associated with implementing and maintaining sophisticated data analytics systems can be prohibitive for smaller firms. Additionally, many SMEs lack the technical knowledge required to fully utilize Big Data. The complexity of Big Data tools, combined with the shortage of skilled professionals, further aggravates the challenges SMEs face. Organizational culture also plays a significant role in the adoption of new technologies. In many SMEs, traditional attitudes can create resistance to change, making it difficult to integrate data-driven approaches into existing business models [8,9,10].
A key challenge for SMEs is their lower level of technological maturity. Unlike larger companies, which often have well-established IT infrastructures and dedicated teams for managing data initiatives, SMEs may still rely on outdated systems with limited technological capabilities [11]. This lack of advanced technology not only hinders their ability to collect and analyze data effectively but also impedes overall digital transformation. Larger enterprises, by contrast, benefit from economies of scale, enabling them to invest in cutting-edge technologies and attract skilled professionals, creating a stark difference in Big Data adoption between SMEs and their larger counterparts. To better understand the differences in Big Data adoption between SMEs and larger organizations, established theoretical models such as diffusion of innovation (DOI) and the technology–organization–environment (TOE) framework provide valuable insights. The DOI theory suggests that SMEs may be slower in adopting Big Data due to their limited resources and higher sensitivity to external pressures, such as market demand or financial risks [12]. The TOE framework further helps explain how Big Data adoption is shaped by three key factors: the technological, organizational, and environmental contexts in which a firm operates. SMEs face significant technological and organizational barriers compared to larger enterprises, which may contribute to their slower adoption of Big Data solutions [13,14,15,16].
Given the significant role of SMEs in the global economy, addressing these challenges is essential. SMEs make up most businesses around the world and are key drivers of employment, innovation, and economic growth. As the digital economy grows, the ability of SMEs to remain competitive will increasingly rely on their capacity to utilize data-driven insights [17,18,19]. However, existing research on Big Data adoption in SMEs is limited, with most studies focusing on larger enterprises. This gap is concerning, especially as SMEs need to adapt quickly to the demands of the digital era. Without a clear understanding of the specific factors influencing data analytics adoption in SMEs, they risk being left behind in an increasingly competitive market [13,14]. This systematic literature review aims to fill this gap by analyzing the impact of Big Data on SME performance. Through a review of existing research, the study seeks to identify the key drivers and barriers that affect data analytics adoption in SMEs. The review will focus on challenges such as financial constraints, lack of technical expertise, organizational culture, and technological maturity, exploring how these factors shape SMEs’ ability to leverage Big Data [14,15]. Additionally, the review will assess the broader impact of Big Data adoption on SME performance, highlighting potential benefits in terms of innovation, competitiveness, and responsiveness to market changes. This analysis will provide valuable insights for academic researchers and SME managers alike, offering practical recommendations to overcome barriers and improve SME performance through Big Data [15,16].
Ultimately, this research adds to the ongoing discussion on information systems and technological innovation by emphasizing the critical role of Big Data in the future success of SMEs. By focusing on the specific challenges and opportunities unique to SMEs, the review provides a fresh perspective on the factors influencing Big Data adoption in smaller businesses [17,18]. The findings will inform future research and policy aimed at supporting SMEs in their digital transformation. Additionally, these insights will be invaluable for SME managers as they navigate the complexities of Big Data, enabling them to build more data-driven organizations and remain competitive in the global market. As SMEs continue to face the pressures of digital transformation and increased competition, their ability to harness Big Data will be a key factor in determining their success moving forward [19,20]. Table 1 presents a comprehensive review of various studies focusing on the role of Big Data, analytics, and digital transformations in small and medium-sized enterprises (SMEs). It covers key aspects such as contributions to the field, theoretical frameworks, and identified research gaps. The table aims to highlight critical pros and cons of each study while identifying areas where further research or analysis is necessary. By examining comparative insights and gaps, this review contributes to understanding how Big Data adoption, analytics, and related technologies impact SMEs, particularly in operational, financial, and competitive performance. This structured analysis also incorporates different theoretical frameworks, such as the technology–organization–environment (TOE) model, to provide a multi-dimensional view of SME transformations. Each study is critically evaluated to determine its strengths, limitations, and how this review builds upon those findings to fill existing gaps, offering a more comprehensive perspective for future research.
Despite the substantial body of research on Big Data adoption, there remains a significant gap in integrating these studies into a cohesive theoretical framework, particularly one that accounts for the unique challenges faced by SMEs. While many studies explore the benefits and obstacles of Big Data, few systematically contextualize their findings using established technology adoption models, such as diffusion of innovation (DOI) or the technology–organization–environment (TOE) framework. These models are particularly relevant to understanding the barriers to Big Data adoption in SMEs, as they address key dimensions like organizational readiness, technological complexity, and external pressures factors especially pertinent in the resource-constrained environments typical of SMEs.
The TOE framework stands out as a powerful tool for understanding SME-specific challenges, as it highlights how organizational context, technological capabilities, and environmental factors collectively influence technology adoption. By more thoroughly engaging with this framework, future research could provide a clearer understanding of how SMEs navigate the complexities of adopting Big Data, especially in comparison to larger enterprises with greater resources and infrastructure. For instance, SMEs often face issues such as limited technical expertise, financial constraints, and a lack of organizational support—barriers well captured by the TOE framework. Integrating this model into the theoretical discussion offers a structured way to assess how SMEs can overcome these barriers and leverage Big Data to enhance their innovation capacity and competitiveness.
Additionally, there is a lack of empirical research exploring data-driven innovation and digital transformation in SMEs, particularly in developing countries. These regions often experience additional challenges, such as underdeveloped digital infrastructure and limited access to cutting-edge technologies, which can hinder the effective adoption of Big Data. Incorporating more recent research on digital transformation in these contexts would strengthen the theoretical foundation and provide actionable insights for SMEs in similar environments. By focusing on how these businesses can implement Big Data in ways that drive innovation and improve performance, research could offer practical solutions tailored to the distinct constraints and opportunities faced by SMEs in developing economies.
There is a pressing need to build a clear conceptual framework that directly links Big Data capabilities with performance outcomes in SMEs, emphasizing innovation, operational efficiency, and competitive advantage. Such a framework should address not only technological and organizational factors but also consider external market pressures and the broader competitive landscape. By developing this framework, future research can offer a more nuanced understanding of how SMEs can utilize Big Data to transform their business models, enhance decision-making processes, and ultimately gain a sustainable competitive edge. Integrating theoretical models like TOE, DOI, and the concept of data-driven innovation offers a comprehensive approach to understanding the full impact of Big Data on SMEs, creating a more robust and cohesive foundation for future studies.

2.7. Study Risk of Bias Assessment

During our review, we investigated the potential for bias by examining the quality of the studies based on the criteria for our research topic. Three reviewers conducted this assessment. Each reviewer independently analyzed the studies for objectivity, as shown in Table 5 below, followed by a discussion to reach a consensus on the bias risk for each study. No automated tools or software were involved in this assessment process. We manually reviewed the methodologies and results of each study. Bias risk was determined based on factors such as study design relevance, sample size, and data collection methods. Studies with transparent methodologies were considered to have bias risks. We also inspected any conflicts of interest or funding sources that could impact study outcomes, giving preference to studies that openly disclosed conflicts [151].
We also assessed consistency in findings within and across studies, noting any differences or unusual results. This method aimed to ensure high-quality studies in our review while identifying and addressing biases effectively.

2.8. Effect Measures

In the systematic literature review of existing literature, a range of methods were utilized to evaluate the effects of Big Data on different outcomes. For increased profitability, operational efficiency, customer satisfaction, and market share, the primary effect measures included mean difference, statistical significance of correlations, or regression coefficients. When analyzing the factors affecting data implementation, correlation coefficients and statistical significance in regression models were key indicators. Assessing areas like enhanced employee productivity, data-driven practices, process optimization, resource allocation, and competitive advantage involved measures like difference and percentage change from tests. Furthermore, aspects like data usability, accuracy, risks of data loss, communication effectiveness, and compliance adherence were evaluated using metrics such as risk ratios and compliance rates. Challenges in adopting Big Data, such as cost implications or the need for personnel, were measured through the frequency of events and percentage impacts. In studies mentioned in the table summary section, quantitative research approaches utilizing methods like structural equation modeling (SEM) or partial least squares SEM incorporated measures such as SEM results, factor loadings, mean differences, and regression coefficients [151].
For qualitative research, such as case studies and thematic analysis, we used measures like categories, qualitative observations, and findings from case studies. Mixed-method research involves a combination of measures (such as regression coefficients and SEM results) along with insights (like thematic analysis findings). In studies that examined the effects on performance, we looked at economic performance through variations in regression coefficients and statistical significance. Operational and environmental performance was assessed by differences, effect sizes, and coefficients from structural equation modeling. Sustainability and competitive advantage were assessed using effect sizes, regression coefficients, and correlation measures.

2.9. Synthesis Methods

In compiling the research necessary for our systematic literature review about the impact of Big Data on the performance of small and medium-sized enterprises (SMEs), we took a systematic approach to identifying high-quality studies. The processes of synthesis are significant, and the general tasks are demonstrated in Figure 6. The supplemental strategies deployed in reviewing are the key components in the integrity and connection of the study’s findings. Compiling the research for our systematic literature review on how Big Data affect the performance of small and medium-sized enterprises (SMEs), we took a systematic approach to ensure that we included relevant high-quality studies [151].
The eligibility criteria, preparing data for synthesis, accumulating and presenting data, and synthesizing the data were included. Furthermore, we also looked at the reasons for heterogeneity in study results and carried out a sensitivity analysis to test the robustness of our synthesized results.

2.9.1. Study Eligibility Criteria

We compared the characteristics of studies focusing on how they aligned with our key themes and findings concerning Big Data and SMEs. Our selection criteria prioritized papers that directly related to our topic and those with several citations. We carefully examined abstracts to comprehend each study’s objectives and methodologies. We specifically looked for studies that explored the impact of data on SMEs using mixed methods. To ensure the credibility of our sources, we excluded literature reviews and included only peer-reviewed papers from sources. By using web filters, we avoided publications guaranteeing that the studies in our review were trustworthy and authoritative. The studies selected for review ranged from 2014 to 2024 and encompassed articles, journals, conference papers, theses, and dissertations. Each paper underwent peer review to meet our quality standards, while literature reviews were excluded to maintain the integrity of our review [151].

2.9.2. Data Preparation for Synthesis

To ensure the data were ready for presentation and analysis, we followed a series of steps to ensure accuracy and consistency. Initially, we worked together to go through our Excel dataset focusing on the names of authors and paper titles to identify and remove any duplicate entries. We used Excel’s “Remove Duplicates” function to eliminate rows while considering situations where the same article might have been listed with titles by the same author. For records with missing data that could not be reliably estimated due to inaccuracies, we decided to exclude those articles from our analysis. In cases where data were missing, we labeled them as “Not Specified” rather than “Not Applicable” to accurately represent the gaps. We also standardized all data entries for consistency by converting text formats into formats as needed and ensuring the same formatting for all data entries [151].

2.9.3. Data Visualization and Tabulation Methods

To visualize patterns and detect inconsistencies, we created pivot tables. These tables helped us easily identify any differences, such as variations in how journal articles were classified. By creating representations like line charts, bar graphs, and other charts mentioned in Table 6, we could track the research distribution over time and prevent errors that may occur during manual review, ultimately improving the quality and dependability of our data synthesis [151].

2.9.4. Synthesis Methodology

A systematic approach was used to synthesize the study findings, utilizing a set of criteria organized in an Excel spreadsheet. This structured method helped in comparing and analyzing aspects of the studies included, focusing on variables like the title, publication year, and source databases (Google Scholar, Scopus, and Web of Science), with their respective number of studies found, represented in Table 7. The studies were grouped by journal name, research type (article journal, conference paper, book chapter, dissertation/theses), and citation count [151].

2.9.5. Exploration of Heterogeneity Causes

The synthesis was enhanced by considering the field or subject area specifically related to data analytic techniques for small and medium-sized enterprise (SME) performance. Factors like industry context (SMEs, startups) and geographical location played roles in distinguishing studies based on the landscape (developed versus developing countries). Further categorization involved examining types of data technologies employed as indicated in Table 8 (Hadoop, Spark, NoSQL databases) and analytic techniques utilized (machine learning, data mining, predictive analytics) [151].

2.9.6. Sensitivity Analysis

Moreover, the study also reviewed the technology providers mentioned (Cloudera, Hortonworks, IBM, AWS) and different technology implementation models (on-premises cloud-based hybrid). The study’s structure, research approach (whether quantitative, qualitative, or mixed methods), sample size, and sample characteristics were examined to explore the variety of methodologies used in the research. The methods of gathering data (interviews, surveys, observations, document reviews) and analyzing data (analysis, thematic analysis) were reviewed to understand how each study handled and interpreted the information.
To bring together the findings, we thoroughly examined aspects such as IT performance metrics (like data processing speed, scalability, and data accuracy), business performance metrics (including efficiency, revenue growth, and cost savings), organizational impacts (such as employee satisfaction and customer satisfaction), and long-term effects (such as business sustainability and competitive advantage). This method allowed us to identify patterns and trends from the studies, leading to an analysis of the data.
This approach effectively considered a range of studies. It laid a strong groundwork for combining the results. By categorizing studies based on criteria, we were able to assess the presence and level of statistical diversity. Differences in research design, sample sizes, data collection methods, and the utilization of Big Data technologies and analytical techniques indicated varying degrees of statistical diversity. This evaluation guided our synthesis process by considering differences in study outcomes and enabling us to reach conclusions [151].

2.10. Reporting Bias Assessment

In our analysis, we carefully considered the potential for reporting bias, where certain outcomes are selectively shared while others are omitted. Such bias can skew conclusions, making certain effects appear stronger or more consistent than they may be. To address this, we reviewed the methodology and results sections of each study to ensure the outcomes aligned with the original research objectives. We assessed whether all relevant findings were reported, noting instances where data appeared incomplete or missing, and considering how this could impact the overall analysis. We also accounted for the possibility of publication bias, where studies with favorable outcomes are more likely to be published compared to those with neutral or negative results. To mitigate this risk, we included a diverse range of studies from various sources and contexts, ensuring a more comprehensive representation of the evidence.
Table 5 summarizes the overall quality of each study, categorized by selection, comparability, and outcome/exposure. The outcome/exposure category was particularly important for assessing reporting bias, as it evaluates how thoroughly a study reported its findings. Studies that demonstrated greater transparency in reporting received higher ratings, while those that omitted key information were rated lower. By cross-referencing these ratings in Table 5, we accounted for reporting bias in our overall assessment. Studies with lower ratings in this area were examined more closely to determine if their conclusions were affected by incomplete reporting. This approach allowed us to present a more balanced and accurate summary of the evidence [151].

2.11. Certainty Assessment

This section outlines the approach used to evaluate the reliability of the evidence gathered concerning Big Data’s impact on SME performance, ensuring the findings were both credible and robust. The literature reviewed was systematically analyzed using a set of five quality assessment (QA) criteria, as outlined in Table 9. These criteria were selected to assess the dependability, relevance, and overall quality of the studies, forming a solid basis for the conclusions drawn in this research. This evaluation process was essential to determine the strength of the evidence and ensure that the findings accurately reflect how Big Data influence various aspects of SME performance, including business growth, operational efficiency, and financial outcomes.
The quality assessment (QA) questions were rated on a scale from zero (0) to one (1). A score of 0 was assigned for a “no” response, 0.5 given when the criteria were “partially” met, and a score of 1 was awarded for a “yes” response. This rating system was uniformly applied to all five questions (Q). As a result, each piece of literature being reviewed could achieve a total score of up to 5 points. The outcomes of the quality assessment for the literature reviewed are detailed in Table 10.

3. Results

Figure 7 outlines the essential components that influence the results, such as study selection, study characteristics, and the risk of bias, all of which play a crucial role in shaping the reliability of the findings. Additionally, it highlights the importance of synthesizing individual study results, which is key to forming comprehensive conclusions. The figure also emphasizes the significance of considering reporting biases and assessing the certainty of evidence to ensure that the presented results are both accurate and dependable. Each of these factors is critical in interpreting the overall findings, offering a clearer view of the data.

3.1. Study Selection

The selection process for research papers is outlined in Figure 8. A total of 93 papers were chosen from three major databases, with their distribution presented as percentages. Most of the papers (63.44%) were sourced from Web of Science, followed by 22.58% from Google Scholar and 13.98% from Scopus. These papers were selected based on specific inclusion and exclusion criteria to ensure that only the most relevant studies were included in the final analysis of this review.
The literature review revealed that small and medium-sized enterprises (SMEs) encounter significant challenges in leveraging Big Data capabilities. The primary barriers include resource constraints, limited data expertise, and a lack of organizational readiness. These factors hinder SMEs’ efforts to improve decision-making, operational efficiency, and competitive advantage. Several studies emphasize the importance of technological infrastructure and employee skills in overcoming these challenges. Financial limitations often restrict SMEs from investing in advanced analytics tools, while gaps in data literacy impede effective data utilization. Additionally, the absence of a clear strategic vision for data collection and analysis leads to the underutilization of valuable insights, perpetuating inefficiencies and missed opportunities for innovation. These barriers prevent SMEs from fully harnessing the potential of Big Data, directly impacting their performance and market competitiveness.
The review also highlighted notable gaps in research, particularly concerning regional differences in Big Data adoption among SMEs. There is a scarcity of studies focusing on SMEs in developing regions, overlooking how diverse economic and infrastructural conditions influence data implementation. While many studies address technical and organizational barriers, fewer explore cultural factors that affect Big Data strategies, such as leadership attitudes toward innovation and risk-taking. Addressing these gaps is crucial for understanding how Big Data can effectively transform SMEs across different contexts and industries, facilitating their growth and competitiveness in an increasingly data-driven marketplace.

3.2. Study Characteristics

Figure 9 shows the research findings regarding the impact of Big Data on the performance of SMEs, illustrating a shifting level of interest between 2016 and 2024.
Table 11 provides a momentary view of the research published during this period, categorized by type of journal article and conference paper. Interestingly, no scholarly articles were available for the years 2014 and 2015, suggesting that the incorporation of data into SME operations was not a focus during those specific years. It is reasonable to assume that during that period, the utilization of data technologies was still in its early phases, with more emphasis placed on larger corporations rather than SMEs. The table highlights a steady increase in publications from 2016 through 2024, with a notable rise in journal articles.
Starting from 2016, there is evidence of a gradual rise in research attention, beginning with five publications in 2016 and steadily increasing to six in 2017. However, there was a decrease in activity in 2018, when two papers were published. This could indicate a temporary shift in research priorities or challenges faced during the early stages of implementing Big Data practices within SMEs. In 2019 and 2020, there was a rise in the number of published papers, reaching a peak of 17 in 2020. This increase may be attributed to the growing acknowledgement of how Big Data can benefit SMEs driven by the greater availability of Big Data tools and a heightened awareness of their advantages.
Figure 10 presents the distribution of titles by country identified in this systematic literature review. The bar chart provides a detailed breakdown of the number of titles across various countries, highlighting regions with a higher concentration of research activity. Notably, China and Italy emerge as prominent contributors, suggesting focused academic and research efforts in these areas. This visualization is crucial for understanding the global landscape of the reviewed literature, offering insights into the geographic distribution and influence of research on this topic.

It highlights how BD enhance financial performance, drives growth, and supports environmental sustainability by optimizing operational efficiency and enabling strategic decisions.
Key elements, such as organizational readiness, leadership commitment, and the integration of Industry 4.0 technologies, are essential for realizing these benefits. The table also addresses common challenges linked to BD adoption, such as financial limitations and a lack of expertise, while suggesting potential solutions like cloud-based analytics and data-driven business models. It further demonstrates how BD adoption serves as a conceptual framework for exploring innovation in resource-constrained environments, contributing to the development of new models and future research directions.

3.3. Risk of Bias

When examining how Big Data affect the performance of small and medium-sized enterprises (SMEs) it is crucial to grasp the approaches utilized in research studies, as these greatly impact the trustworthiness and relevance of the results. Figure 11 below displays the usage of research methods in studies on this subject, emphasizing the potential bias risks linked to each method. A variety of approaches such as case studies, surveys, and experimental designs have been utilized, each having its strengths and weaknesses when addressing inquiries about how Big Data influence SMEs.
Figure 11 presents the data showing that surveys are the most widely used method, representing 47% of the studies reviewed. Although surveys are efficient for gathering large datasets, they come with certain limitations, primarily the risk of self-reporting bias. Respondents may provide incomplete or inaccurate information, especially when dealing with complex topics like Big Data utilization in SMEs. Moreover, surveys often simplify the intricate dynamics of Big Data implementation, focusing on easily quantifiable outcomes without capturing the underlying complexities that shape these outcomes. This is particularly problematic in the SME context, where challenges related to Big Data adoption are often context-specific and difficult to quantify.
Case studies, accounting for 28% of the research, offer valuable in-depth insights into individual SME experiences, but face limitations in terms of generalizability. These studies focus on specific contexts, limiting broader conclusions about Big Data’s influence on SME performance across various sectors and regions. Experimental and quasi-experimental designs constitute 13% and 9% of the studies, respectively. While these methods help establish causality, their controlled environments may not accurately reflect the real-world complexities SMEs face in their operations. The minimal use of quantitative methods such as meta-analysis (1%) and document analysis (2%) highlights an additional bias, which is the underrepresentation of long-term trend analyses and assessments of historical data. This imbalance limits our understanding of how Big Data influence SME performance over time, as the lack of longitudinal or cross-sectional studies prevents the identification of sustained patterns and impacts in data-driven decision-making.
The predominant reliance on surveys introduces a reporting bias that can distort overall findings in Big Data research on SMEs. Surveys tend to focus on general trends and perceptions, but may overlook complex, context-specific challenges like resource constraints, data literacy gaps, and integration difficulties. These challenges are often better explored through qualitative methods such as case studies or interviews, which are underrepresented in the current body of research. The heavy bias toward quantitative methods risks producing a narrow and incomplete view of Big Data’s true impact on SMEs.
Emerging themes from the studies include resource constraints, where many SMEs lack the financial and human capital to invest in advanced data analytics technologies and skilled personnel. This resource scarcity significantly affects their ability to leverage Big Data for improved decision-making, innovation, and competitiveness. Another crucial gap is data literacy, as many SME employees lack the skills to interpret and act upon data insights. Inadequate integration of Big Data into existing processes and systems further leads to fragmented data sources and inefficient workflows, which limit the potential benefits of data-driven decision-making. Cultural resistance to change also impedes the adoption of data-driven practices, thereby restricting performance improvements.
These challenges are not isolated, but are intrinsically linked to SME performance outcomes. For instance, limited resources not only prevent SMEs from acquiring Big Data tools but also create a cycle of underperformance, where their inability to fully utilize data constrains growth and innovation. Similarly, insufficient data literacy can result in poor strategic decisions, eroding competitive advantage. These factors—resource limitations, data literacy gaps, and integration difficulties—directly affect operational efficiency and hinder SMEs’ ability to respond swiftly to market changes. Without adequate integration, SMEs struggle to compete in increasingly data-driven markets.
While the studies reviewed offer valuable insights, significant gaps remain. The sector-specific factors and regional disparities in data access and technology adoption are underexplored, limiting our understanding of how these variables influence Big Data challenges for SMEs. The overreliance on surveys and quantitative methods also restricts the depth of findings. Future research should adopt a mixed-method approach, incorporating both quantitative and qualitative analyses to provide a more nuanced and comprehensive understanding of how Big Data can enhance SME performance. Longitudinal studies, more qualitative research, and region-specific investigations would be particularly useful in addressing reporting biases and offering a more complete picture of Big Data’s impact on SMEs.

3.4. Results of Individual Studies

Figure 12 shows how different business performance results are seen in the context of how Big Data impact SMEs’ performance based on an analysis of 93 studies.
As shown in Figure 12, the most common outcome observed in the studies is business improvement, accounting for 29.03%. This indicates that the integration of Big Data technologies by SMEs is predominantly linked to business enhancements, particularly through improved decision-making and better alignment with market demands. Economic performance and revenue growth are also prominent outcomes, representing 27.96% and 19.35% of the studies, respectively. The considerable percentage associated with economic performance suggests that Big Data often provide SMEs with advantages such as increased market presence and a stronger competitive edge. Revenue growth highlights the financial benefits that SMEs gain from utilizing Big Data, underscoring the impact on business prosperity.
Cost savings, which appear in 16.13% of the studies, show that while reducing costs is acknowledged as a benefit of Big Data, it is not the primary objective for many SMEs. This could be because SMEs are more inclined to invest in Big Data for business expansion and market growth, rather than focusing solely on cost-saving strategies.
The lower percentages for enhanced data-driven innovation (4.30%) and operational efficiency (1.08%) suggest that these aspects are not as frequently highlighted in the literature. This may be due to the challenges that SMEs face in leveraging Big Data for innovation, such as limited financial and technical resources. Similarly, the minimal focus on operational efficiency may indicate that although Big Data can improve operations, its significance is often overshadowed by its impact on business strategy and market positioning. Furthermore, the “not specified” category (1.08%) implies that a small number of studies did not clearly define performance outcomes, likely due to a more qualitative approach in their analysis.
While these results provide valuable insights into how Big Data influence various performance outcomes, it is crucial to discuss the challenges SMEs face in adopting Big Data. Many SMEs lack the technical expertise and infrastructure needed to fully utilize Big Data for innovation and operational improvements, which may explain the lower representation of innovation and efficiency outcomes. Additionally, SMEs may be overlooking potential cost-saving opportunities as they prioritize growth and revenue generation. Future research should delve deeper into these challenges and identify strategies to help SMEs overcome these barriers. This would enhance our understanding of how SMEs can better balance growth, innovation, and efficiency within their Big Data strategies.

3.5. Results of Syntheses

Figure 13 below illustrates the systematic process followed in synthesizing the results of the selected studies. It begins with the initial step of reporting synthesis results and proceeds through detailed assessments of study characteristics and biases, statistical synthesis, investigation of result variability, and sensitivity analyses. This visual representation ensures clarity in understanding the sequential steps taken to achieve a comprehensive and robust synthesis of the literature.

3.5.1. Study Characteristics and Bias Assessment

The breakdown of data collection methods in Figure 14 reveals a strong qualitative focus, with document analysis accounting for 36.56%, followed by interviews at 33.33%, observations at 25.81%, and surveys at 4.30%. This diversity offers a broad perspective, but also introduces challenges and potential biases specific to each approach. The dominance of document analysis and interviews indicates a reliance on qualitative methods that provide detailed, context-rich insights, but may also be prone to subjectivity and case-specific bias. Observations contribute valuable real-world data, while the limited use of surveys suggests that quantitative analysis is underrepresented, potentially limiting the scope for more generalizable findings.
Several key themes emerge across these studies, particularly regarding the resource and capability constraints SMEs face in adopting Big Data. Resource limitations are consistently cited as a major challenge, with SMEs lacking the financial means and skilled personnel necessary to invest in and maintain advanced data analytic tools. This resource gap directly influences Big Data performance outcomes by inhibiting the ability of SMEs to implement data-driven strategies effectively. The lack of data literacy is another significant barrier, with insufficient skills among SME employees restricting their capacity to interpret data insights. This issue is especially problematic in light of the methodological bias towards qualitative approaches, as detailed case studies and interviews may capture nuanced individual experiences, but lack the breadth necessary to generalize about the pervasiveness of these challenges across different sectors or regions. This imbalance in data collection methods contributes to a skewed understanding of how widespread these challenges truly are.
The limited use of surveys (4.30%), which could provide more generalizable and quantitative insights, further emphasizes the risk of bias in the overall dataset. The underrepresentation of quantitative approaches restricts the ability to draw broad, statistically supported conclusions about the impact of Big Data on SME performance. Additionally, the dominance of qualitative methods, such as document analysis and interviews, could lead to an overreliance on subjective interpretations of issues like resource constraints and data literacy. This could amplify findings that are specific to certain cases and may not be applicable across a wider SME population.
When these challenges are linked to Big Data performance outcomes, it becomes evident that SMEs’ internal limitations—such as resource scarcity, data illiteracy, and difficulties in integrating Big Data systems—impede their ability to effectively utilize Big Data. These constraints not only hinder operational efficiency but also prevent SMEs from using data to drive innovation and remain competitive. For instance, resource limitations restrict SMEs from acquiring essential tools for Big Data implementation, creating a cycle of underperformance and missed growth opportunities. Similarly, a lack of data literacy results in poor data interpretation, which impairs strategic decision-making and weakens SMEs’ competitive edge in an increasingly data-driven market.
Several gaps in the literature emerge from these methodological biases. While qualitative methods provide valuable depth and context, the lack of quantitative data collection limits our understanding of how Big Data influence SME performance across different sectors and regions. Geographical disparities in data access and technology adoption are underexplored, and there is limited focus on how sector-specific challenges shape Big Data adoption by SMEs. To address these gaps, future research should employ a mixed-method approach, incorporating more quantitative methods like surveys and longitudinal studies alongside qualitative analyses. This would enable a more comprehensive understanding of the complexities involved in Big Data implementation and their impact on SME performance.

3.5.2. Statistical Synthesis Results

Figure 15 below provides a detailed breakdown of the analysis methods employed in the study. The pie chart reveals that “statistical analysis” represents 63% of the methods used, underscoring the study’s strong quantitative focus. In contrast, “thematic analysis” constitutes 37%, reflecting the inclusion of substantial qualitative analysis. This distribution highlights the study’s balanced approach, integrating both quantitative and qualitative methodologies to offer a comprehensive view of the research findings.
The figure highlights the predominance of statistical methods, which is crucial for evaluating the quantitative aspects of the study’s findings. By illustrating the emphasis on statistical analysis, the chart helps in assessing the robustness of the statistical syntheses, such as meta-analysis, and their impact on the overall results. Additionally, the presence of thematic analysis underscores the inclusion of qualitative insights, providing a fuller picture of how different types of data were integrated to form the study’s conclusions. This comprehensive view supports a more refined interpretation of the statistical synthesis results, ensuring that both quantitative and qualitative data are considered in the overall analysis.

3.5.3. Factors Contributing to Result Variability

Figure 16 in this section highlights key factors contributing to variability in the results observed across different professional groups, namely, data analysts, IT professionals, and small and medium-sized enterprises (SMEs). As illustrated, SMEs dominate in terms of contribution to result variability, representing 73.12% of the total, while data analysts and IT professionals show considerably lower percentages, at 13.98% and 12.90%, respectively. This significant disparity suggests that SMEs, with their diverse applications and needs, have a more substantial influence on the variability of results compared to the specialized roles of data analysts and IT professionals. The analysis of these figures provides critical insight into the different capacities and roles these groups play in shaping outcomes, underscoring the importance of focusing on SMEs when addressing performance inconsistency in Big Data and IT-related initiatives.

3.5.4. Sensitivity Analyses

Sensitivity analyses are crucial for evaluating the robustness and reliability of data-driven models in various fields. These analyses help determine how changes in input variables impact the outcomes of a model, ensuring that the insights derived are consistent and meaningful under different conditions. Figure 17 below highlights the prominence of different analytical techniques, with data mining and predictive analytics being commonly used approaches. Notably, 44.09% of the cases did not specify the analytical technique, which may indicate a lack of transparency or clarity in methodology. However, data mining (26.88%) and predictive analytics (16.13%) demonstrate their importance in refining models, while machine learning, at 12.90%, plays a critical role in automating complex pattern recognition. Sensitivity analyses using these techniques allow for deeper insights, especially when exact methodologies are not always clear, helping to validate the robustness of findings across multiple domains.

3.6. Reporting Biases

Reporting biases occur when certain research findings are more likely to be shared, leading to incomplete or skewed data interpretations. Figure 18 highlights reporting biases in the literature, with quantitative studies representing the majority at 54%, while mixed-method and qualitative studies are less common, making up 22% and 17%, respectively. This suggests a preference for quantitative research, potentially limiting the depth of insights, as mixed-method and qualitative approaches offer valuable context and a deeper understanding that quantitative studies might overlook.
The reliance on quantitative studies indicates a focus on easily measurable Big Data outcomes, such as financial performance, while qualitative insights into challenges like technical expertise or innovation receive less attention. This imbalance may obscure a complete understanding of the factors influencing Big Data adoption in SMEs. Grouping studies into broader themes, such as drivers of Big Data adoption, barriers, and industry-specific insights, can help uncover patterns and gaps in current research. This approach enriches the synthesis of results and contributes to a more balanced perspective on how Big Data impact SMEs across various contexts, providing a more comprehensive understanding of reporting biases in this field.

3.7. Certainty of Evidence

Figure 19 shows how different data collection methods are distributed in the studies we reviewed to evaluate the impact of Big Data on SMEs’ performance. This visual representation helps us understand how the choice of methods affects the reliability of the study’s conclusions.
Document analysis, which constitutes 37% of the methods used, provides a solid foundation for the evidence. This method relies on existing records and documents, which are typically stable and verifiable. As a result, document analysis contributes significantly to the certainty of the findings by offering consistent and well-documented data that enhance the reliability of the evidence. Interviews make up 26% of the methods and offer rich, detailed insights that can deepen the understanding of the subject matter. However, the certainty of the findings from interviews can be influenced by respondent biases and subjective interpretations. For instance, if interviewees have differing perspectives or personal agendas, their responses may introduce variability into the results, which can affect the overall certainty.
Surveys account for 33% of the methods and are valuable for gathering data from a wide range of SMEs. Nevertheless, the certainty of survey-based findings can be impacted by response biases and limitations in sample representativeness. Response biases occur when survey participants provide socially desirable answers rather than their true opinions, which can skew the results. Additionally, if the survey sample is not representative of the broader SME population, the findings may not be generalizable, thus affecting the certainty of the conclusions. Observations, which make up only 4% of the methods, contribute minimally to the certainty of the evidence due to their limited scope and application. Observations are often constrained by their specific context and may not capture the broader patterns or trends relevant to the study, reducing their overall impact on the certainty of the findings.
Figure 19 illustrates how each data collection method impacts the certainty of the evidence. Document analysis provides reliable and consistent data, while interviews and surveys introduce various degrees of variability due to potential biases and representativeness issues. Observations, though insightful, have a limited effect on the overall certainty. By employing a combination of these methods, the study achieves a comprehensive understanding of how Big Data affect SME performance, though with varying levels of confidence in the conclusions drawn. This detailed explanation demonstrates how Figure 19 supports the analysis of the certainty of evidence in this study.

Strategic drivers, such as data-driven innovation, blockchain adoption, and upskilling the workforce, are key enablers in achieving the expected outcomes of improved productivity, reduced costs, and enhanced competitiveness. Each industry faces unique challenges, but the roadmap offers a structured, step-by-step approach to overcome these challenges and capitalize on opportunities through digital transformation.

5. Discussion

This paper discusses the importance of Big Data in small and medium-sized enterprises (SMEs) with a focus on key dimensions concerning implications and challenges, as well as one methodological aspect. Analysis shows that Big Data remarkably improve SMEs’ performance in business decisions, economic performance, and revenue growth.
RQ1: 
How does Big Data capability impact SMEs’ performance?
The research finds that BD capability has a notable impact on SMEs’ performance, as shown in Figure 12 and Figure 16. Figure 12 highlights that the most common outcome of BD adoption by SMEs is business improvement (29.03%), achieved through enhanced decision-making and market responsiveness. Economic performance (27.96%) and revenue growth (19.35%) are also key outcomes, underscoring the financial advantages SMEs gain from using BD. While cost savings (16.13%) are acknowledged, SMEs tend to focus more on growth and expansion than on operational cost reduction. Notably, the relatively low emphasis on data-driven innovation (4.30%) and operational efficiency (1.08%) suggests that SMEs may struggle in these areas due to resource constraints or limited expertise. Figure 16 further demonstrates that SMEs account for 73.12% of result variability, indicating their central role in shaping the outcomes of BD initiatives. These findings offer a comprehensive view of how BD capability enhances SME performance, particularly in terms of strategic decision-making, financial growth, and competitive positioning.
RQ2: 
What are the critical factors influencing the successful implementation of Big Data on SMEs?
The critical factors influencing BD implementation in SMEs are examined through Figure 11 and Figure 18. Figure 11 shows that the most common research methods used are surveys (47%) and case studies (28%), each with distinct advantages and limitations. Surveys may introduce self-reporting biases, while case studies provide in-depth insights but lack generalizability. Experimental designs (13%) and quasi-experimental methods (9%) offer causal inferences, but struggle with external validity. The scarcity of quantitative methods (1%) and document analysis (2%) further emphasizes the need for diverse research approaches to capture the full range of factors affecting BD implementation. Additionally, Figure 18 reveals a reporting bias toward quantitative studies, with fewer qualitative and mixed-method studies. Addressing this imbalance and utilizing a broader range of research methods can improve understanding of the factors that drive or hinder successful BD adoption in SMEs.
RQ3: 
How can awareness and understanding of Big Data be leveraged to enhance productivity in SMEs?
Awareness and understanding of BD are crucial for leveraging their full potential in SMEs, as highlighted in Figure 10 and Figure 17. Figure 10 shows that countries such as China and Italy have seen a growing recognition of BD’s benefits, reflected in increased research activity. This heightened awareness has contributed to productivity improvements by encouraging the adoption of BD tools. Figure 17 highlights the prominence of data mining (26.88%) and predictive analytic (16.13%) techniques, which are essential for refining decision models and ensuring accurate insights. By deepening their understanding of BD capabilities, SMEs can make more informed decisions and optimize operational efficiency, ultimately driving productivity growth.
RQ4: 
What are the challenges SMEs face in integrating Big Data into their existing systems and operations?
The challenges SMEs encounter when integrating BD into their existing systems and operations are highlighted in Figure 8 and Figure 14. Figure 8 shows that a majority (63.44%) of research papers on this topic are sourced from Google Scholar, reflecting the broad scope of challenges across diverse contexts. Figure 14 focuses on the methods used for data collection, revealing that document analysis (36.56%) and interviews (33.33%) provide valuable qualitative insights into the obstacles SMEs face. These challenges include resource limitations, technical difficulties, and issues with integrating BD into existing infrastructure. This methodological focus underscores the importance of understanding these barriers to help SMEs navigate the complexities of BD implementation.
RQ5: 
How can SMEs effectively adapt their decision-making processes to harness the full potential of Big Data analytics?
SMEs can adapt their decision-making processes by adopting a more data-driven approach that allows them to harness the full potential of BD analytics. The findings in Figure 12 and Figure 16 emphasize that SMEs often prioritize business improvement and growth, but there is significant untapped potential in areas such as operational efficiency and innovation. By integrating advanced analytical techniques like data mining and predictive analytics (Figure 17) into their decision-making processes, SMEs can not only improve performance outcomes but also foster greater innovation and competitiveness. A shift towards data-driven decision-making will enable SMEs to unlock the full benefits of BD and better align their strategies with market demands.

6. Conclusions

This systematic review reveals that Big Data offer significant benefits for small and medium-sized enterprises (SMEs), including improved decision-making, enhanced operational efficiency, and revenue growth. However, the review also identifies significant barriers to adoption, such as financial constraints, limited technical expertise, and inadequate organizational readiness. These challenges must be addressed for SMEs to fully leverage Big Data’s potential. The key practical implication is that Big Data adoption can drive competitiveness and innovation, but SMEs must invest in appropriate financial resources, develop technical skills, and ensure alignment between Big Data initiatives and core business objectives.
To address these barriers, SMEs should prioritize building a culture of data-driven decision-making, supported by leadership and organizational commitment. Enhancing data literacy across teams and breaking down organizational inertia are essential to successful integration. Creating a strategic roadmap that links Big Data capabilities with specific business goals will help SMEs maximize their return on investment. Industry leaders and policymakers can play a crucial role by offering tailored support frameworks that include access to funding, training programs, and infrastructure designed to meet the unique needs of SMEs. Specific recommendations for researchers include conducting more empirical studies and practical case analyses, particularly focusing on underexplored regions such as developing economies. Future research should aim to provide actionable insights and practical examples that demonstrate how SMEs can overcome barriers and successfully implement Big Data. The review highlights the importance of aligning Big Data adoption with strategic business objectives, investing in technical training, and fostering an organization-wide commitment to data-driven innovation. These steps are crucial for ensuring that SMEs not only adopt Big Data but also use them effectively to achieve sustainable growth and improved performance.
