This section reviews total quality management (TQM) concepts and research on occupational safety and health (OSH) and how TQM concepts and practices can facilitate and enable occupational safety and health performance in organizations. It starts with a bibliometric review of the two approaches and their implementation worldwide and in the context of Saudi Arabia.
2.1. Bibliometric Analysis of TQM and OSH
Bibliometric analysis is the statistical evaluation of published scientific research. The primary aim of bibliometric analysis is to evaluate the importance and impact of the research topic through the analysis of articles that have been published in scientific databases during a specific period. Usually, bibliometric analysis is used to reveal the importance and the relevance of the research, and to assess the attention and interest by researchers, research funding institutions, and practitioners.
The term “bibliometrics” refers to the practice of analyzing bibliographic data from published works of literature through the application of quantitative statistical techniques. Some examples of bibliographic data include the publishing year and the country of origin. In this paper a descriptive analysis of total quality management research fields, focusing on occupational safety and health publications, is presented. As a result, a body of research has been produced, which serves as a foundation for the current empirical study. This part intends to examine the effect of implementing TQM on occupational safety and health performance in organizations. It helps to discover changes, trends, and directions for future research investigations in this specific research area. This method identifies, evaluates, and synthesizes the existing body of published work that researchers, scholars, and practitioners have produced [
20]. There is evidence to support the claim that bibliometric reviews have evolved into a “basic scientific activity that would support scientific investigations” [
20,
21,
22].
One of the benefits of using the bibliometrics review approach is that it makes one more aware of the scope of the research and the theoretical foundation for a particular research topic. It is vital to do a bibliometric review of any subject to comprehend the degree of previous research that has been undertaken, as well as to identify the areas that need additional research in the field and flaws that would exist within those areas. In this section, the topic of total quality management within the occupational safety and health area has been implemented using bibliometric analysis [
20].
The purpose of this section is to present a bibliometric review of the existing papers in leading journals and specialist journals from 1994 to 2022 to investigate the most common themes in the fields of TQM and OSH. In another aspect, this research aimed to identify the research gap within the context of Saudi business organizations.
The technique suggested for the bibliometric analysis has been outlined in earlier research [
21,
22] and consists of the following basic steps: (i) study design; (ii) data collection; (iii) data analysis; (iv) data visualization; (v) interpretation. World of Science and Scopus databases were used in order to collect the bibliometric data. Scopus draws its data from the Elsevier Core Collection database, and Web of Science takes it from the Clarivate database. The Scopus and WoS are considered to be primary sources of bibliometric information in many research fields. The collection contains over 500,000 high-quality scientific articles that are peer reviewed and published worldwide in over 240 different fields. The “journal” search for research literature was conducted through academic journals in the fields of total quality management and occupational safety and health management. These top academic journals and specialist journals are published in nine well-known databases, which are as follows: Emerald, American Society for Quality (ASQ), Inderscience, Taylor & Francis, Elsevier, Informs, IEEE Xplore, ProQuest, and John Wiley & Sons. Informs is a database that ProQuest owns.
In October 2022, access was made to the databases and a general search was conducted using the following keywords to narrow the focus: “total quality management” AND “occupational safety and health” OR “TQM” AND “OSH”. After completing an available search by subject, we obtained all of the publications with the keywords in the title and abstract. The analysis took into account documents published between 1994 and 2022 in the databases.
The bibliometric analysis covered a total of 347 documents, which may be divided into two categories: articles (75%) and review papers (10%). Some of the documents have more than one categorization, and one of those classifications is called a conference paper with 10%. The remaining 5% of papers in the databases are editorial content, notes, and book chapters. The journals and books in the Elsevier Core Collection and Clarivate have been indexed in at least one category.
For the aim of this study, we considered some research criteria to make it within the scope of our research area. The research criteria were to consider only articles in the areas of engineering, business management, accounting, and environmental science to cover the occupational safety and health aspects. On the language side, we considered only papers published in English. Finally, we limit our database research to only the keywords “Total Quality Management” and “in Occupational Safety and Health”. Thus, of the more than 50,000 documents retrieved, only 347 have been included in the analysis. For this collection of articles, tags such as author, title, abstract, country, citation record, author affiliation, and author keywords have been saved. Early Access Articles waiting for year assignment were kept in the collection and considered as 2022 since these works may unveil trends. The primary software resource for the bibliometric study was “Bibliometrix”. It is an open-source tool for quantitative research in “Scientometrics” and bibliometrics, programmed in R-tool that provides powerful data analysis and visualization functionalities. In addition, “VoSviewer” was used to identify the author keywords with highest citations [
21].
The results of the bibliometric analysis are shown in
Figure 1, which shows the annual number of articles published between 1994 and 2022 and the citation number trendline. It can be noted that there is a continuous growth in research related to the contribution of total quality management to the occupational safety and health aspect over time. This growth was apparent from the beginning of the nineties of the last century and the growth continued for nearly twenty years, after which the number continued growing because of the development of the scientific areas of business management. Citations over the years show similar trends. This indicates that the implementation of TQM for OSH performance improvement remains of interest to researchers and professionals worldwide.
These findings demonstrate that though there was a relative drop in the publications’ annual average rate in the last year (2022), there is still interest in the TQM and OSH research though the emergence of new concepts such as Quality 4.0 and Safety 4.0, as a result of the introduction of Industry 4.0 technologies in all organizations management aspects. An average annual growth rate was seen for total quality management and its integration into OSH worldwide, as measured in terms of science and technology output. The annual number of citations has shown a substantial increase, far more than the number of articles. This increase in research interest may be explained by the shift in the management paradigm from normal management to total management, which incorporates TQM, OSH, and environment management systems as drivers and enablers for organizational performance. Even though TQM and OSH research has been going on for 28 years, the field is not showing any signs of slowing down or declining, as measured by the number of scientific publications and research citations. It can also be noted that total quality management has played a fundamental and strong role in everything related to engineering and industrial sciences, emphasizing that it is an integral part of the organizations’ occupational safety and health performance. On the other hand, it is clear that there is a correlation between total quality management and occupational safety and health in general, and this indicates its importance exclusively in processes to achieve organizational goals and sustainable results.
The geographical distribution of the research and work related to the integration of TQM and OSH was addressed.
Table 1 examines the prevalence of studies in countries regarding research in TQM and OSH. As shown in
Table 1, most scientific publications were issued in Europe (39.24%), the US and Canada (28.07%), and Asia (17.93%). This finding is not surprising, since the common factor among most countries producing research is that they are among global economic leaders. From this figure, it can easily be shown that there is a paucity of research on TQM and OSH in the context of the Middle East and North Africa (MENA) region, with a contribution of (2.19%) of the research. Only a very limited number of studies were recorded in the case of Saudi Arabia, Jordan, and the United Arab Emirates [
17,
18,
23,
24]. This finding motivated the authors to perform the present empirical study on the implementation of TQM on OSH performance in the Saudi context.
The last step in the bibliometric analysis was to analyze the author keywords. This procedure aims to define the keywords used in the 347 papers identified in the previous steps. It examines the interaction between the most cited keywords. As shown in
Figure 2, which presents the author keywords interactions, two main categories of keywords are identified. The first category contains the major tools and techniques that focus on total quality management. The top five keywords in this category were improvement, quality environment, 5S, Kaizen, and lean manufacturing. The second category is the keywords related to occupational safety and health include safety management system, safety training, total safety management, safety responsibilities, and, finally, risk assessment. From
Figure 2, it can be seen that total quality management and occupational safety and health systems are well integrated and interrelated from a research point of view. This would be considered as a good indication that since total quality management has been demonstrated to be an enabler for high quality products and services, it can also ensure a high performance in occupational safety and health programs in organizations [

The bibliometric analysis shows the importance and impact of the scientific research and articles published concerning the integrated impact of TQM and OSH. This analysis reveals that the TQM and OSH research areas have received increased interest from researchers, academics, research institutions, and professionals all over the world. This interest is still present in the literature though the new technological advancement brought by Industry 4.0 and the subsequent emergence of new paradigms such as Quality 4.0 and Safety 4.0. In addition, the scarcity of publications dealing with the Saudi context would foster an interesting aspect of the research at both the global and national Saudi levels.
2.2. Total Quality Management
Quality is the measure of the capability of all components of an organization to satisfy the stated and implied needs of the customers; it is the measure of how a product or a service will perform satisfactorily in service and is suitable for its intended purpose. The quality concept is not confined to one particular side of the organization, it includes all its operational units, starting with management and ending with resources, production, auditing, stores, and even suppliers and employees. This is achievable only through a commitment to a set of systems divided into units to reach compatibility and harmony between departments and management units [
5,
6,
25]. This is known as total quality management, a modern and holistic management philosophy that originated mainly as a method of work and a means to develop the performance of for-profit and not-for-profit organizations [
25,
26,
27,
28,
29,
30,
31,
32,
33,
34,
35,
36,
37,
38]. Total quality management (TQM) consists of organization-wide efforts and an integrated system of principles, tools, and best practices to create an environment that supports the organization and continuously improves its capability to deliver products and services that contribute to customer satisfaction [
29,
30,
35,
37,
38,
39].
Various definitions of total quality management have been reported in the literature. Total quality management has been defined as a management approach that focuses on delivering products and services with the highest quality, maximizing customer satisfaction, and meeting national and international regulatory standards. Total quality management is then defined as a business strategy that drives the organization strategy towards achieving customer satisfaction through continuous improvement and full people involvement [
6,
40,
41]. Researchers confirmed that total quality management is about creating a culture of excellence in performance, where management and employees work continuously and diligently to achieve customer expectations and requirements [

45,
46,
47,
48,
49,
50].
Table 2 summarizes 15 criteria to successfully implement total quality management in manufacturing and service organizations as advocated by Zairi [
6].
Quality management scholars and gurus such as Deming, Juran, Crosby, Feigenbaum, Ishikawa, and Zairi have stressed the fact that the customer defines quality. Consequently, total quality management generates customer satisfaction and loyalty, which would lead to building a competitive advantage for the organization. They further stressed that, in conjunction with customer focus, the reduction of the costs of waste and rework are equally important to the organization in achieving its business strategy [
6,
25,
26,
40,
41,
42,
43,
44,
45,
46,
47,
48,
49,
50]. According to Kiran [
50], TQM highlights continuous improvement and a systems perspective to achieve customer satisfaction and long-term organizational success. It involves problem prevention, process improvement, and a team-based approach to problem solving and product improvement, incorporating all departments in the organization. Furthermore, Lim [
7] emphasized that TQM is the system of activities aimed to achieve customer delight, empowered employees, higher revenues, lower costs, and improved competitive advantage.
Successful implementation of TQM in world class organizations in services and manufacturing has been reported through (a) scholars’ model (Deming 14 points; Juran 10 steps; and Crosby 14 points) for quality management, (b) business excellence models such as the EFQM, MBNQA, KAQA, Deming Prize, etc., and (c) international standards for quality management (ISO 9001:2015). All these approaches are articulated on a set of fundamental pillars, principles, and practices that constitute the critical success factors for its implementation in organizations [
6,
7,
8]. Depending on the approach for TQM implementation, a multitude of fundamental concepts have been widely agreed upon among scholars and researchers. However, there are common principles mentioned, such as leadership commitment, continuous improvement, process management, customer satisfaction, training and education, teams, and organizational culture [

49,
50,
51,
52].
To ensure a suitable selection process for the commonly used principles in total quality management implementation, the authors reviewed the TQM fundamental concepts and practices agreed upon in the open literature and from leading professional organizations in quality, such as the American Society for Quality (ASQ, 2022) [
28] and the International Standards Organization (ISO) [
53].
Table 3 shows the set of the fundamental pillars of TQM that will be used to build the theoretical framework of the present empirical study.
2.3. Occupational Safety and Health Performance
In today’s global economy, the organization’s leadership has been increasingly aware of the need for occupational safety and health management systems which aim to create a safe working environment for their workforce. Setting up an effective safety and health management system is crucial in order to reduce problems relating to work accidents and ill conditions in organizations. Safety management systems contribute to the creation of safe working environments and help to reduce incidents, fatality frequencies, and property damage [
9,
10].
Recent statistics from the International Labor Organization indicated clearly that occupational health and safety is a complex international problem for organizations’ management and the whole of society, and that it must always be a top priority. According to the US Bureau of Labor Statistics, the number of work injuries and illnesses per 100 full-time workers is stable at very high levels, at 2.8 (November 2020 statistics). This is despite the strict application of national or international legal legislation in business environments. The costs associated with these incidents are estimated at billions of dollars annually and represent one of the challenges facing organizations in an era characterized by globalization, intense competition, and technological and social disruptions, which may affect the organization. According to the National Institute for Occupational Safety and Health (NIOSH) in the United States of America, the costs (direct and indirect) of work-related injuries and illnesses were estimated at
$170 billion in 2019 [
64].
To overcome this situation and avoid these losses, professional experts and organizations have been working hard to develop effective safety systems based on best practices and international standards. Academic research and experts’ work have been devoted to addressing the risks and hazards related to occupational safety and health that organizations face and which negatively affect their performance and even their reputation. Industrial organizations are even required to work hard to achieve the requirements of their customers in products and services, as well as achieving the legal requirements imposed by regulatory and supervisory government authorities regarding the safety of the workforce [
14,
15,
65].
Leading international and professional organizations such as The National Safety Council in the US (NSC) and the ILO provide guidance in the form of fundamental elements that should be addressed in order to establish successful safety and health programs based on the synthesis of research, safety and health expertise, and world class best practices. These elements are recommended to be part of the foundation for an occupational safety and health initiative and program. These elements have been identified by Reese [
66] and Aichouni [
3] as:
Hazard recognition, evaluation, and control;
Workplace design and engineering;
Safety performance management;
Regulatory compliance management;
Occupation health;
Information collection;
Employee involvement
Motivation, behavior, and attitudes;
Training and orientation;
Organizational communications;
Management and control of external exposures;
Environmental management;
Workplace planning and staffing;
Assessments, audits, and evaluations.
According to Reese [
64] and Osborne and Zairi [
8] it is important for organizations to consider the factors that affect OSH programs and influence their performance; these would be classified under four categories, as shown in
Table 4.
Managing occupational safety and health is an integral part of managing the whole business. Organizations need to implement OSH programs for performance and operational excellence through either adopting international standards, such as ISO 45001:2018 for occupational safety and health management systems [
65,
67], or other models and systems such, as OSH Act or ILO-OSH 2001 Guidelines [
66,
68,
69,
70,
71,
72]. All these OSH management systems or programs are articulated partially or fully on the fundamental elements described in
Table 4. The International Labor Organization (ILO) has produced guidelines on the development of occupational safety and health management systems, ILO-OSH 2001, which integrate OSH fundamental elements and total quality management concepts. Such an approach has been widely adopted in research work since the early work of Zairi [
5], Weinstein [
12,
13], Osborne and Zairi [
8], Salim et al. [
68], and more recently by Aichouni [
3]. It is also worth noting that the Saudi National Program for occupational safety and health (OSH) [
4] adopts this approach, which is shown in
Figure 3.
This international model has been used by leading organizations for achieving excellence in the management of occupational safety and health. It identifies the five interconnected elements which constitute the OSH management system; these elements include: (a) OSH policy and people involvement, (b) organizing, (c) planning and implementation, (d) performance evaluation, (e) improvement. These five elements will be used as constructs for the present research. It can be seen that the framework of this OSH program embraces some aspects of the TQM approach, in the sense that:
Policies supportive to human resources development are needed within the OSH program.
A systematic approach to OSH management is needed.
Continuous improvement of the OSH program is necessary.
Supportive organizational culture towards quality and safety and commitment of leadership, with a wide participation of employees at all levels is needed.
