1. Introduction

The Technology Acceptance Model (TAM) and the Resource-Based View (RBV) provide a robust theoretical foundation for understanding how ERP, CRM, and HRM systems operate in small and medium-sized enterprises (SMEs). TAM focuses on two key factors: perceived usefulness and perceived ease of use, both of which influence managers' and employees' decisions to adopt specific technologies. In the context of SMEs, where resources and technical expertise are often limited, these technologies must integrate seamlessly into daily operations to achieve widespread acceptance. In particular, the perceived ease of use becomes crucial, as many SMEs do not have the capacity for extensive training or large IT departments, making user-friendly systems essential for adoption. Conversely, RBV views these systems as strategic resources that can offer SMEs a competitive edge. When effectively implemented, ERP, CRM, and HRM systems become valuable, rare, inimitable, and non-replaceable (VRIN) resources that enable SMEs to improve decision-making, enhance operational efficiency, and respond more agilely to market changes. By combining TAM and RBV, this study highlights both the immediate practical benefits and the long-term strategic advantages that SMEs can gain from adopting these systems [2,3]. The demand for innovative solutions is growing as businesses navigate an increasingly competitive and complex market. Innovation is no longer a luxury but a necessity for organizations to sustain their competitive advantage. However, for innovation to thrive, the role of employees and their work behaviors must be examined in detail. Human resource (HR) policies that foster innovative work behavior are crucial, as they encourage employees to develop new ideas and apply them in meaningful ways. HR practices that promote involvement and participation, rather than focusing solely on control, aim to enhance employee skills, motivation, and engagement in decision-making processes. These involvement-driven HR strategies help create work environments that are conducive to creativity and innovation, which are critical for SMEs looking to stay competitive. However, while the role of HR in driving innovation has been acknowledged, there is still a lack of detailed research exploring how different HR strategies can interact to influence innovation, particularly within the context of SMEs [4,5].
Moreover, in a knowledge-based economy, employees involved in research and development (R&D) play a pivotal role in a company's success by driving innovation and maintaining a competitive edge. Attracting, retaining, and motivating these high-value employees requires HRM systems that are specifically designed to address their unique needs. Different management practices, especially in relation to R&D personnel, can vary widely between organizations, and these variations can significantly impact innovation outcomes. A deeper understanding of these practices is needed to provide insights into how they can be optimized for enhancing innovation and productivity within SMEs [7,8]. Additionally, technological advancements, such as the integration of Digital Object Identifiers (DOIs) into ERP systems, offer SMEs a strategic advantage in managing and sharing critical information. By using DOI features for internal documents, project files, and knowledge databases, SMEs can ensure accurate and up-to-date information is accessible to all team members, improving collaboration and decision-making. The incorporation of advanced technologies like artificial intelligence (AI) and cloud computing into ERP systems further enhances operational efficiency by providing real-time insights and analytics. These tools not only streamline workflows but also allow SMEs to respond swiftly to market dynamics and customer needs, creating a more resilient and competitive organization. As demonstrated by the system in Figure 1, the integration of these functional systems is essential in fostering long-term growth and sustainability in SMEs [9,10].
To position this study within the broader body of literature, a comparative analysis of existing reviews on functional systems in SMEs was conducted. This analysis provides insight into how previous research has addressed the adoption and impact of ERP, CRM, and HRM systems in SMEs, highlighting both the strengths and limitations of each study. While many reviews offer valuable frameworks and practical recommendations, they often lack comprehensive empirical evidence, focus too narrowly on specific industries, or fail to generalize their findings across diverse SME contexts. Table 1 presents a detailed comparison of these reviews, illustrating key contributions, pros, and cons from each source [11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40].
The shortcomings identified in existing reviews highlight the need for a more comprehensive and practical study on the integration of functional systems in SMEs. Many prior studies are limited in scope, focusing on specific regions, industries, or technologies, which restricts their generalizability and applicability across different SME contexts. Additionally, while theoretical frameworks are well-developed, many studies lack practical, implementable strategies that consider the unique challenges faced by SMEs, such as resource constraints and limited technical expertise. Furthermore, several reviews offer conceptual models without sufficient empirical validation or real-world case studies, making it difficult for SMEs to apply these findings effectively. By addressing these gaps, the proposed systematic review will provide a broader, more integrative analysis of ERP, CRM, and HRM systems, offering actionable recommendations tailored to SMEs. This study will also focus on overcoming the specific challenges that SMEs encounter, making it a valuable contribution to the literature on functional systems in small and medium-sized enterprises.

1.1. Research Questions

The following research questions will be explored in the proposed survey:
  • How do ERP, CRM, and HRM systems impact managerial decision-making and resource allocation in SMEs?
  • In what ways do ERP, CRM, and HRM systems enhance workforce efficiency and employee productivity in SMEs?
  • What operational improvements are achieved through the adoption of ERP, CRM, and HRM systems in SMEs, particularly in reducing manual tasks and automating workflows?
  • How can the integration of AI and machine learning into ERP, CRM, and HRM systems further enhance innovation and competitiveness for SMEs?

1.2. Rationale

The integration of ERP, CRM, and HRM systems in SMEs is a critical area of study, particularly because SMEs often lack the resources and technical expertise that larger enterprises possess. These systems offer potential for enhancing decision-making, improving productivity, and driving operational efficiency, but SMEs face unique challenges in implementing them. Given the limited financial and technical resources of SMEs, this study seeks to explore how these systems can be effectively integrated to support both managerial and employee functions. Additionally, it addresses the broader issue of market competitiveness, as SMEs must navigate dynamic environments while maintaining lean operations. By identifying the specific benefits and challenges associated with ERP, CRM, and HRM system adoption in SMEs, this study aims to provide actionable insights for their sustainable growth and competitive advantage.

1.3. Objectives

The aim of the study is to provide a comprehensive analysis of how ERP, CRM, and HRM systems enhance decision-making, productivity, and operational efficiency in SMEs, while identifying key challenges and offering practical recommendations for effective system integration. The proposed survey intends to fulfil the following objectives:

  • To explore the potential for AI and machine learning integration within ERP, CRM, and HRM systems to drive innovation and maintain competitiveness in the SME sector.

1.4. Research Contribution

This systematic review offers a comprehensive analysis of the role those functional systems such as ERP, CRM, and HRM play in supporting managers and employees in small and medium-sized enterprises (SMEs) from 2014 to 2024. The study synthesizes current literature to explore how these systems enhance decision-making, operational efficiency, and overall workplace productivity. The review not only highlights the most effective approaches to system integration but also identifies key challenges that SMEs encounter during adoption, providing valuable insights for maximizing both managerial oversight and employee engagement in the SME environment.
  • This review fills a critical gap in the existing research by providing a detailed overview of how functional systems support both managerial leadership and staff productivity in SMEs. While many studies have examined individual systems, this review uniquely combines the impact of ERP, CRM, and HRM on daily operations, offering a more holistic understanding of their effects on SMEs.
  • The study establishes a structured framework connecting functional systems to leadership and employee support, offering a foundation for understanding how these tools facilitate managerial decision-making and enhance workflow efficiency. By improving communication, automation, and resource management, these systems contribute directly to employee satisfaction and overall productivity.
  • The review identifies crucial areas for further exploration, particularly in the customization of functional systems for SMEs. It emphasizes the need for more research into advanced technologies like artificial intelligence (AI) and cloud computing, which could significantly enhance system performance for SMEs, addressing their specific needs and limitations.
  • This review also provides actionable data for policymakers and organizations aiming to support SMEs. By offering insights into the adoption barriers SMEs face—especially in developing countries where they play a critical role in economic development—the study suggests policy initiatives that could facilitate easier access to these systems, thus improving their overall impact on business performance.

1.5. Research Novelty

This study brings a unique contribution to the field by offering a comprehensive assessment of the impact that ERP, CRM, and HRM systems have on the performance of SMEs. Previous studies have not thoroughly examined the combined effects of these systems, especially with a focus on the factors that influence their successful or hindered adoption. This review bridges that gap by analyzing the key enablers and barriers that affect system implementation, ranging from budgetary constraints to organizational culture and technological readiness.
  • The research provides novel insights by investigating underexplored topics, such as the influence of limited technical expertise, budgetary challenges, and resource constraints on the adoption of these systems in SMEs. By focusing on the specific challenges faced by SMEs, the study offers a more targeted understanding of how these functional systems can be effectively utilized to improve operational performance.
  • This review not only identifies the challenges but also delivers focused recommendations, particularly for SMEs looking to integrate CRM, ERP, and HRM systems. The research offers practical suggestions for overcoming adoption barriers, such as providing training programs, improving system customization, and leveraging emerging technologies like AI to enhance operational outcomes.
This work is organized into five key sections.

2. Materials and Methods

The methods for assessing how HRM, CRM, and ERP affect small and medium-sized business's (SMEs') efficacy are described in this section. The study looks at research published in the last ten years, with a focus on papers that were published between 2014 and 2024. The methodology lays the groundwork for a thorough analysis of each component in the parts that follow including instructions for choosing studies, data sources, and the process used to review the gathered literature. Figure 2 illustrate the proposed framework that will be employed in this survey.

2.1. Eligibility Criteria

Functional systems and their significance in assisting managers and employees in SMEs must be specifically examined in the study. ERP (Enterprise Resource Planning), CRM (Customer Relationship Management), and other management information systems are examples of technology or process-oriented systems intended to improve SME operations. These systems are classified as functional systems. The review included studies published within the last 10 years to ensure the relevance and applicability of the findings to the current technological and business environment. Excluded studies focused solely on worker support or managerial support without looking into how the two intersected. The proposed inclusion and exclusion criteria are tabulated in Table 2.

2.2. Information Sources

When performing the systematic review on "Functional Systems and Their Support for Managers and Workers," numerous databases and sources were used in conjunction with an extensive search technique. A comprehensive examination of scholarly publications and conference papers is ensured by consulting primary databases such as Google Scholar, Web of Science and SCOPUS.
  • Google Scholar is a free search engine that indexes academic content from a variety of fields, including books, journals, theses, conference papers, and patents. It provides a wide range of peer-reviewed research and gray literature by compiling content from academic publications, professional associations, universities, and other intellectual organizations. Its sophisticated search features make it possible for users to locate scholarly materials, keep track of citations, and investigate related works, making it an invaluable resource for academics, professionals, and researchers everywhere.
  • An extensive collection of academic literature from many fields, including the social sciences, humanities, sciences, and arts, is accessible through the extensive Web of Science research database. Researchers can locate and examine academic papers, journal articles, and conference proceedings using its citation indexing and tracking services. Citation metrics are also used to evaluate the significance and impact of research.
  • Science, technology, health, the social sciences, and the arts and humanities are just a few of the fields that are covered by the extensive abstract and citation database SCOPUS. It offers tools for citation tracking, impact analysis, and literature reviews in addition to access to a sizable library of peer-reviewed journals, conference papers, and patents. Scholars frequently utilize SCOPUS to locate pertinent research, monitor research patterns, and assess the significance of scholarly publications.

2.3. Search Strategy

The process of conducting a systematic review, beginning with the formulation of research questions, is depicted in Figure 3. These inquiries support the selection of a research approach, including organizing an SLR (Systematic Literature Review), defining inclusion and exclusion criteria, choosing research sources, and selecting search terms. The process then moves on to selecting research articles via a search and assessment process, which is essential to guaranteeing references of the highest calibre. The next step involves taking data out of the selected research articles, with an emphasis on assessing data integrity. In order to answer the research questions and wrap up the research process, data must be compiled during the execution phase of the research data.
To find studies that provided characteristics on functional systems, assistance for managers, and support for employees and SMEs, search keywords were developed specifically for this systematic review. A duplicative process of exploratory searches was used to choose index key-terms. Terms that failed to produce studies meeting the inclusion requirements were eliminated. The comparable terms of the recommended phrases were determined in order to make sure that they included the equivalent terms of the core keywords. Matchable terms were found using synonyms; for example, "Functional Systems" might also mean "Support Systems." We got, "Small and Medium Enterprises" for "SMEs" and "Workers" for "Managers". The code string was ("Enterprise Resource Planning" OR ERP) AND ("Customer Relationship Management" OR CRM) AND ("Human Resource Management" OR HRM) AND ("Small and Medium Enterprises" OR SME OR SMEs) AND (Manager* OR Employee*) AND (Support OR Satisfaction OR Efficiency OR Performance) which had the use of AND & OR, based on the research title: Functional Systems and Their Support for Managers and Workers in SMEs. The logic "OR" operator encompasses any of the selected terms, while the logic "AND" operator includes all of the selected keywords. The code string helped us finding 17800 research articles in Google scholar from 2014-2024 in 0.40 seconds.

2.4. Selection Process

Strict selection procedures were used to guarantee a relevant collection of papers for the review on "The impact of Customer Resource Management, Enterprise Resource Management, and Human Resource Management on SME performance." A process was adhered to by the reviewers to choose papers for the systematic review titled "The Impact of Customer Resource Management, Enterprise Resource Management, and Human Resource Management on SME Performance." They used a search code that included terms linked to SMEs, performance, and effect along with keywords like "Enterprise Resource Planning," "Customer Relationship Management," and "Human Resource Management." Each reviewer was given a database to compile research papers from, either Web of Science, Scopus, or Google Scholar. Each reviewer first collected 98 papers, which were then checked according to the following inclusion criteria: the papers had to be published in English, relevant to the topic, and published between 2014 and 2024. Additionally, the papers had to have a research framework that addressed the impact of HRM, ERP, and CRM on the performance of SMEs. Additionally, exclusion standards were used to group the studies. The selected papers were entered into an Excel spreadsheet for evaluation. Reviewers carried out an additional evaluation to verify compliance with the inclusion criteria and resolve any discrepancies by eliminating documents as needed to keep the data accurate and pertinent.

2.5. Data Collection Process

The process of gathering data is summarized in the section that follows. It shows how many reviewers were involved, how they collaborated or worked alone, how information was obtained and verified from study researchers, and what online database tools were utilized. We used the Web of Science and Scopus platforms to obtain data from the University of Johannesburg (UJ) library database during our data collection process. A search code that targeted English-language publications published between 2014 and 2024 served as the basis for our investigation. Journal articles, conference papers, textbook chapters, theses, and dissertations were all included in our selection criteria. We found 20 studies on the Web of Science, 37 studies from Scopus, and 51 from Google Scholar after adjusting our search parameters.
We split up the articles among the three authors to reduce job duplication and speed up the process. A time range was given to each author; one covered the years 2014 to 2016, and another one covered 2017 to 2020. A third covers 2021 to 2024. We made sure that our research had no duplicate papers by using this strategy. Each author gathered information on their own. We collaborated and edited the Excel document in real-time by sharing it online. All three authors worked together to examine the Excel sheet after the initial data-entering stage was finished to ensure data accuracy. We resorted to the documentation for adjustments in cases where there were contradictions, such as incorrectly identifying paper types. The Google Scholar database was also utilized to gather data. For each reviewer, we separated the papers we had into groups of three.
Together, we selected 51 papers from Google Scholar to be included in the analysis. We looked through the abstracts, read the introductions, and then double-checked the topic names and keywords to make sure they aligned with our study emphasis to make sure these publications are relevant. We also considered the number of citations, which serves as a gauge for the authority and impact of the paper. Furthermore, since Google Scholar did not have an extraction tool like Web of Science and SCOPUS, each reviewer selected publications themselves. Figure 4.

2.6. Data Items

The purpose of this Systematic Literature Review is to compile data that explores how big data affects small and medium-sized businesses (SMEs). To ensure a thorough understanding of the subject, the results are categorized based on the research questions.

2.6.1. Data Collection Method

The outcomes for which the data were searched are listed and defined in this part. These outcomes include performance gains, cloud computing adoption, and the operational performance of SMEs. All relevant results, covering a range of time points, techniques, and analyses, that were compatible with these metrics were sought for each outcome area. Based on predefined criteria, a systematic review was utilized to highlight the most appropriate and dependable data when many outcomes were convenient inside the same domain. This made sure that each outcome's analysis provided a methodologically sound and comprehensive picture.
The following are the main factors that are used to evaluate how ERP, CRM, and HRM systems affect the functionality of SMEs' systems. The most crucial components, methods, and findings that establish the effectiveness of those functional systems' use are shown in the figure.

2.7. Study Risk of Bias Assessment

We investigated the possibility of bias during our assessment by evaluating the studies' quality in accordance with the standards relevant to our area of study. This assessment was carried out by three reviewers. After examining the papers individually for objectivity, as indicated in Table 5 below, each reviewer gathered to discuss and determine the bias risk associated with each study. This evaluation process did not use any automated instruments or software. Every study's methodology and findings were examined by manually. Based on factors including sample size, data collection techniques, and study design relevance, bias risk was determined. Research employing open methods were thought to carry bias risks.

2.8. Effect Measures

Different effect measures were used to synthesize and present the findings in this systematic review on "Functional Systems and Their Support for Managers and Workers" within SMEs. These measures were chosen based on the type of outcomes reported in the included studies. The following effect measures were used:
  • Managerial Support Outcomes
Studies reporting on how functional systems improve decision-making efficiency among managers used the mean difference to compare the amount of time or the quality of decisions before and after these systems were implemented. The mean difference, which is usually determined by surveys or Likert scales, was used to examine the degrees of managerial satisfaction with their roles before to and following the implementation of functional systems.
  • Worker Support Outcomes
For This metric was used to compare task efficiency levels before and after functional systems were put in place, including task completion times and total number of tasks done. Odds ratios were computed to estimate the probability of higher job satisfaction after system adoption for studies that revealed the percentage of employees who were satisfied with their jobs both before and after the installation of functional systems. After functional systems were introduced, changes in work-related stress levels which are usually measured using self-reported stress scales were measured using the mean difference.
  • Combined Managerial and Worker Support Organizational Performance Outcomes
Research on productivity gains in SMEs that implemented functional systems vs those that did not employ risk ratios to assess the probability of increased productivity in the former group. Employee Turnover: Hazard ratios were employed in research looking at how functional systems affected employee turnover to assess the risk of turnover over time between companies that adopted these systems and those that didn't. Financial Performance: Financial measures like revenue growth, profit margins, or cost savings were compared before and after the installation of functional systems using the mean difference.
Table 6 organizes the effect measures for various outcomes related to functional systems in SMEs, outlining how each was evaluated. It provides a concise overview of the methods used to analyze managerial, worker, and organizational performance outcomes.

2.9. Synthesis Methods

We used a methodical approach to find high-quality studies to compile the research required for our systematic literature review about the effects of customer resource management, enterprise resource management, and human resource management on the performance of small and medium-sized enterprises (SMEs). As shown in Figure 5, the overall tasks and the synthesis processes are important. The crucial elements in maintaining the integrity and relevance of the study's conclusions are the additional procedures used throughout the review. To make sure that we included important, high-quality studies, we followed a methodical approach when gathering the research for our systematic literature review on the effects of customer resource management, enterprise resource management, and human resource management on the performance of small and medium-sized enterprises (SMEs) [110,111,112,113,114,115,116,117,118,119].
Included are the qualifying requirements, data preparation for synthesis, data accumulation and presentation, and data synthesis. In addition, we examined the causes of research result heterogeneity and performed a sensitivity analysis to evaluate the reliability of our synthesized data. Figure 6.

2.9.1. Selection of Studies and Eligibility for Synthesis

To determine how well the research matched our main themes and conclusions about ERP, CRM, HRM, and SMEs, we examined their features. Papers having multiple citations and those directly connected to our issue were given preference in our selection criteria. To understand the goals and methods of each study, we carefully read the abstracts. We searched for research that used techniques to investigate how functional systems affect SMEs. Literature evaluations were left out to maintain the reliability of our sources. Includes only sources' peer-reviewed articles. We avoided publications that testified to the reliability and authority of the studies in our review by employing online filters. The research that was chosen for examination included theses, dissertations, conference papers, journals, articles, and articles published between 2014 and 2024.

2.9.2. Selecting Which Syntheses Are Eligible

Based on their objectives and the results they assessed, studies were categorized into several synthesis groups. Research on how functional systems affect managerial decision-making, for example, was combined with studies on worker task efficiency, which were synthesized separately. This strategy minimized the possibility of bias and improved the validity of the results by ensuring that only comparable studies were included in each synthesis.

2.9.3. Preparing Data for Synthesis and Display

An attempt was made to get the missing data for studies that lacked summary statistics (such as missing means or standard deviations) by getting in touch with the authors. The study was not included in any quantitative meta-analysis; instead, it was incorporated into the narrative synthesis in the event that data could not be collected. Data conversions were carried out using accepted statistical procedures to permit inclusion in quantitative synthesis in studies that reported medians and interquartile ranges rather than means and standard deviations. When needed, effect sizes like odds ratios, risk ratios, and hazard ratios were transformed into a standard metric (such standardized mean difference) to make comparing results between studies easier. This was especially crucial for research utilizing various scales or methodologies to measure comparable outcomes [110,111,112,113,114,115,116,117,118,119].

2.9.4. Synthesis Procedures

The study findings were synthesized in an organized way using a set of criteria arranged in an Excel spreadsheet. With an emphasis on characteristics like the title, publication year, and source databases (such Google Scholar, SCOPUS, and Web of Science), this organized strategy assisted in comparing and assessing various elements of the studies included. Table 7 shows the number of studies for each of these databases. Journal name, research kind (article journal, conference paper, book chapter, dissertation/theses), and citation count were used to categorize the studies [110,111,112,113,114,115,116,117,118,119].

2.9.5. Exploration of Heterogeneity Causes

Many factors contribute to the observed variety in results when examining the heterogeneity of findings among studies from 2014 to 2024 on ERP, CRM, and HRM systems for SMEs with an emphasis on managerial and staff assistance. The varying sizes and industries of SMEs are a primary source of heterogeneity, as they have an important effect on system outcomes, uptake, and implementation success. For instance, ERP systems may provide different levels of assistance to manufacturing SMEs than to service-based SMEs, where CRM systems are more important. The availability of trained personnel and regional IT infrastructure are two examples of geographic factors that influence the efficacy and user satisfaction levels.
Some systematic reviews have used subgroup analyses to separate findings depending on company size, industry type, and region to investigate these reasons of heterogeneity. Furthermore, there are differences in the software integration capacities and customization choices amongst various systems (CRM, HRM, ERP), which leads to inconsistent results concerning usability and performance impact. Further adding to the variation are studies that go further into the employee perspective and frequently describe varying experiences with system usability, training, and engagement.

2.9.6. Analysis of Sensitivity

For this systematic review, both quantitative and qualitative synthesis methods were employed to ensure a comprehensive analysis of ERP, CRM, and HRM systems in SMEs. Where sufficient data were available, a meta-analysis was conducted using a random-effects model to account for heterogeneity in study designs, SME sizes, and system implementations. This allowed for a more robust quantitative synthesis of key outcomes, such as improvements in managerial decision-making and employee productivity. In cases where meta-analysis was not feasible, a thematic analysis was applied to qualitative data, identifying common themes like "decision-making improvements," "barriers to adoption," and "employee support." This combined approach strengthens the overall impact of the findings by providing both statistical insight and deeper thematic understanding [110] – [119].

The synthesis procedures included preparing data for analysis, classifying research by objectives, and choosing studies based on qualities. Based on research compatibility, narrative synthesis or meta-analysis was used, with sensitivity and subgroup analyses guaranteeing solid, objective conclusions.

2.10. Reporting Bias Assessment

We were quite aware of the potential for reporting bias in our analysis, which occurs when some results or conclusions are disclosed while others may not. This type of bias has the potential to skew conclusions by inflating the strength or consistency of some effects. To address this problem, we looked over each study's methodology and results sections to make sure the conclusions were consistent with the initial objectives. We made sure that all pertinent results were displayed. We took note of any incomplete or missing data and considered the potential impact these shortcomings could have on the analysis. We also acknowledged the potential for publication bias, in which research with positive findings has a higher chance of being published than studies with neutral or unfavorable conclusions. We ensured a broader viewpoint by including a wide range of papers from different sources and locations to reduce this danger [110,111,112,113,114,115,116,117,118,119]. This enabled us to obtain a more precise image of the available data.

2.11. Certainty Assessment

This section describes the methodology used to assess the validity of the data collected on the effects of HRM, CRM, and ERP on the performance of SMEs, guaranteeing the results are solid and reliable. As shown in Table 9, a set of five quality assessment (QA) criteria were used to methodically investigate the reviewed literature. These standards were used to evaluate the studies' trustworthiness, applicability, and general quality, providing a strong foundation for the findings of this research. Determining the robustness of the evidence and making sure the conclusions appropriately reflect how these Functional systems affect many areas of SME's performance, such as business growth, operational efficiency, and financial consequences, required this review procedure [110,111,112,113,114,115,116,117,118,119].
There is a zero (0) to one (1) rating system for the Quality Assessment (QA) questions. 'No' responses receive a score of 0, 'Partially' met responses receive a score of 0.5, and 'Yes' responses receive a score of 1. Every one of the five questions is rated using the same methodology (Q). Each piece of literature being examined can therefore receive a maximum score of five points overall. Table 10 provides a full overview of the Quality Assessment results for the evaluated literature.

Document analysis, accounting for 40% of the employed techniques, gives the evidence a strong basis. This approach depends on records and documents that are already in existence, which are usually reliable and verifiable. Consequently, by providing consistent and well-documented data that strengthens the credibility of the evidence, document analysis considerably increases the certainty of the conclusions. 24% of the methods involve interviews, which provide rich, in-depth insights that can enhance the comprehension of the subject. Nonetheless, respondent biases and subjective interpretations may affect how certain the results of the interviews are. Interviewees may inject variability into the results, so affecting overall certainty, if their responses reflect various perspectives or personal motivations.
It is about 24% of the approaches that are surveys, which are useful for obtaining information from a variety of SMEs. However, sample representativeness limits and answer biases may affect the reliability of survey-based results. Response biases can distort the results of surveys when respondents give socially acceptable replies instead of their actual thoughts. The results may not be generalizable, which would reduce the certainty of the conclusions, if the survey sample is not typical of the larger SME community. Due to their narrow application and scope, observations—which account for only 12% of the methods—contribute very little to the confidence of the evidence. The limitations imposed by the context of an observation can hinder its ability to reveal wider patterns or trends that are pertinent to the research, so diminishing its overall power to confirm the findings.

Machine learning algorithms can also optimize predictive models for inventory management, customer engagement, and talent management, further improving operational outcomes and innovation capacity.

5. Conclusions

The implementation of ERP, CRM, and HRM systems has a transformative impact on SMEs, improving operational efficiency, decision-making processes, and workforce productivity. By integrating these systems, SMEs can streamline operations, automate workflows, and gain access to critical business data that enables informed, strategic decisions. These technologies empower businesses to enhance customer relationships, optimize resource management, and elevate employee satisfaction, thereby driving growth and competitiveness in an increasingly digital marketplace. However, while this study has effectively demonstrated the current benefits of these systems, a forward-looking approach is necessary to fully understand how emerging technologies such as Artificial Intelligence (AI), Machine Learning (ML), and blockchain can further enhance these systems for SMEs. AI and ML, for instance, can provide predictive analytics that can improve decision-making even further, offering SMEs real-time insights into market trends, customer behavior, and employee performance. Blockchain, on the other hand, has the potential to revolutionize data security, ensuring that the sensitive information managed by ERP, CRM, and HRM systems is safeguarded with the highest level of encryption.
In future research, expanding on the role of these emerging technologies within ERP, CRM, and HRM systems will provide valuable insights into how SMEs can continue to innovate, remain competitive, and adapt to the evolving digital landscape. By adopting a proactive approach, SMEs can harness these advancements to improve not just current operational efficiency but also future-proof their businesses against technological disruption. This forward-looking perspective is vital as SMEs prepare to navigate the next phase of digital transformation, ensuring sustained growth and success.
