The Relationship between Supply Chain Management Practices and Supply Chain Performance in Saudi Arabian Firms

The purpose of this study was to investigate the relationship between supply chain management practices (SCMPs) and supply chain performance (SC performance) within different industries in the Kingdom of Saudi Arabia. An empirical study was conducted on a sample of 196 firms; information was collected from the supply chain managers and those in top management in different industries in the Kingdom of Saudi Arabia. In addition to a series of interviews conducted with managers of the supply chains, a theoretical model was developed depicting the relationship between SCMPs and supply chain performance (SC performance). This model was also tested using multiple regression analysis. The research suggests that SCMPs, including supply chain planning (SC planning), level of information sharing (IS), customer relationship management (CRM), and supplier relationship management (SRM) are all positively related to SC performance. Additionally, SC performance is positively related to FFP. The research employed perceptual performance measures to gauge return on investment, revenue, and sales. Future studies could use actual numbers to better quantify the benefits within this context.


Introduction
The present business environment is a competitive one, but such competitive challenges can be addressed through effective supply chain management (SCM).
As defined by the Council of Supply Chain Management Professionals (CSCMP), SCM refers to the planning and management of all activities surrounding sourcing, procurement, and conversion; logistics planning and management; and the coordination and collaboration that occur among supply chain partners. Saudi companies face challenges in the global market in regard to their competitive edge, and these challenges can naturally affect the performance of a company. Therefore, to ensure sustainability, Saudi companies need to maintain a competitive advantage. One strategy a company can use to sustain a competitive advantage is to maintain effective supply chain SCM. SCM is theorized to consist of individual functional entities that perform their duties in such a way as to provide resources and information to all parts of the supply chain (SC), thereby allowing management to achieve their goals while also maintaining a smooth flow of all parts of the chain Lau & Lee (2000). To this end, SCM is made up of a variety of practices that can mutually raise the performance of and benefit all supply chain members, including suppliers, manufacturers, distributors, and customers (Chopra & Meindl, 2001). Academic researchers and business managers alike have started paying increased attention to supply chain management practices (SCMPs) (Croom, Romano, & Giannakis, 2000;Li, Rao, Ragu-Nathan, & Ragu-Nathan, 2005;Tan, Kannan, & Handfield, 1998). As a result, many firms now consider SCMPs to be one of the most important aspects of developing and maintaining a competitive advantage in the marketplace (Jones, 1998;Li et al., 2005). Therefore, while it is recognized that SCMPs have an effect on a firm, it is necessary to more specifically measure this impact on the firm's performance (Green, McGaughey, & Casey, 2006). From interviews conducted with different supply chain managers and purchasing managers, a problem exists in Saudi companies in that top management does not know the impact of different practices on SC performance, nor do they clearly know which practices have the most impact on SC performance. Despite the increased attention on SCMPs, there is still insufficient research on SCMPs in emerging countries, such as Saudi Arabia. Furthermore, there also been conflicting findings in regards to the impact of different practices on firm performance; for example, Gandhi, Shaikh, & Sheorey (2017) found that customer relationship management (CRM) has a positive impact on firm performance, but Sundram, Ibrahim, & Govindaraju (2011), in their study of SCMPs in the electronics industry in Malaysia, found that CRM did not affect positively on the firm's performance.
The purpose of this current research was to investigate the relationship between SCMPs and supply chain performance (SC performance) in Saudi firms.
Additionally, the results of this study will be able to help managers and other decision-makers take advantage of efficient SCMPs by assisting them in understanding the potential effects of each practice. SCMPs are defined as the set of activities that an organization uses to boost effective management of its supply Y. Y. Alahmad chain (Li et al., 2005). SCMPs are proposed to be a multi-dimensional concept encompassing both the supplier and customer sides. This study has taken items from SC literature and has tested them empirically by using data collected from Saudi firms in a variety of industries; with this information, six supply chain practices are discussed: supply chain planning (SC planning), risk and reward sharing (RR sharing), information sharing (IS), information quality (IQ), supplier relationship management (SRM), and customer relationship management The study contribution is in conceptualizing the complementing impacts of SC planning, RR sharing, IS, IQ, SRM, and CRM practices on SC performance. It makes two contributions. First, to the best of my knowledge, this study is the first research to investigate the relationship between SCMPs and SC performance in the context of Saudi firms.
Second, for SCM practitioners the study shows that implementing the SCMPs are effective ways to improve SC performance. Additionally, it offers supply chain managers overseeing a supply chain advice for what type of practices they should implement.
The current study is organized as follows: section two synthesizes the relevant literature review and hypothesis development. Section three follows with the research design and methodology. Section four discusses the results and hypotheses findings. Lastly, section five discusses the managerial implications, research limitations, and future research.

Literature Review
SCMPs are a set of practices that integrate all levels of the SC, such as suppliers, manufacturers, distributors, and customers, in order to improve SC performance and FFP (Barros, 2006;Koh, Demirbag, Bayraktar, Tatoglu, & Zaim, 2007). Min & Mentzer (2004) identified the concept of SCMPs as that of including an agreed-upon vision and goals, IS, RR sharing, cooperation, process integration, long-term relationships, and agreed-upon supply chain leadership. (Zhou & Benton Jr., 2007) went further and investigated the integration of IS, SC planning, just-in-time (JIT) production, and delivery practice in supply chain management. Sundram et al. (2011) examined the relationship between various SCMPs, including supplier strategic partnership, customer relationship, IS, IQ, postponement, agreed-upon vision and goals, RR sharing, and SC performance. Chong, Chan, Ooi, & Sim (2011) empirically tested a framework that identifies the relationships between SCMPs in Malaysian manufacturing and service firms, practices including those of strategic supplier partnerships, customer relationships, IS, information technology, training, internal operations, operational performance, and innovation performance. Sukati, Hamid, & Baharun (2013) analyzed the data to find the connection between business performance and the implementation of SCMPs which included internal firm relationships, firm-customer relationships, and firm-supplier relationships. To study the causal relationship between SC performance and FFP, Barber, Garza-Reyes, Kumar, & Abdi (2017) developed seven dimensions, which include strategic supplier partnership, IS, IQ, CRM, internal lean practices, postponement, and total quality management. Saragih, Tarigan, Pratama, Wardati, & Silalahi (2020) examined and explained the relationship between operational performance and ten SCMPs including IS and visits to the sites, supplier relationship, inventory management, product development, agility, implementing quality, integration of logistics, transportation, and purchasing activities with the process of manufacturing. The findings of Saragih et al. (2020) showed that sustainable operational performance could be achieved through SCM. Yanya & Mahamat (2020) investigated the influence of SCMPs including logistics integration and organizational learning in SCM perspective to achieve competitive advantages and improve a firm performance. The study was performed on the pharmaceutical industry of Thailand. The findings of this study showed positive significant relationship between organizational learning and competitive advantage, logistics integration, and competitive advantages. Kumar & Kushwaha (2018) provided empirical insights of the relationship between different supply chain management practices (CRM, information technology, information quality) and operational performance of the fair price shops in India. The study affords that three dimensions of SCM practices have a significant and positive relationship with the operational performance.
Beside the impact of SCMPs on SC performance, SCMPs have a great impact on customer satisfaction and loyalty, supply chain pricing, and contract design in SC. For instance, Prathiba (2020) studied the effects of supplier affiliation, customer affiliation, and knowledge sharing on customer satisfaction and loyalty. The study concluded that SCMPs enhance customer satisfaction and loyalty. Chen, Peng, Liu, & Zhao (2017) analyzed the pricing and effort decisions of a SC. The finding suggests that customers are a less possible benefit from a power retailer. When the manufacturer and the retailer have equal bargaining power, customers perhaps benefit from the SC. Xiao, Chen, Xie, & Wang (2020) studied the interactive impacts of retailer's fairness and manufacturer's overconfidence on best possible contract design in a SC. They concluded that the SC achieves the highest profit under the revenue-sharing contract. Table 1 shows how the literature review provides the theoretical foundation for this study.

Hypothesis Development
In this section, we discuss the relationship between SC planning, RR sharing, IS, IQ, SRM, CRM, and SC performance, as well as the relationship between SC Performance and FFP. Figure 1 illustrates the theoretical framework developed for this research. This framework allows for the understanding of the antecedents and consequences of SC performance as described by the relationships between SCMPs, SC performance, and FFP. This framework is underscored by the rationale that implemented SCMPs. Such a framework will lead to an im-ically, this framework shows that SCMPs have an indirect effect on SC performance (Li, Ragu-Nathan, Ragu-Nathan, & Rao, 2006). The SCMPs are conceptualized through six constructs, as seen in Figure 1.  (Min & Mentzer, 2004) x x (Zhou & Benton Jr., 2007) x (Sundram et al., 2011) x

SC Planning
The practices of SC planning are used to process information from suppliers, customers, and internal operations, in turn contributing to the calculation of future demand wherein the various functions between a firm, its suppliers, and customers become synchronized. The importance of predicting the supply chain demand is well-documented (Aviv, 2001;Lee, Padmanabhan, & Whang, 1997), as this forecast can affect different factors of SC performance. The relationship between the predicted SC demand and delivery performance has been well researched (Cook & Rogowski, 1996;Krajewski & Wei, 2001). Additionally, since department alignment is necessary for achieving a firm's objectives, inter-functional coordination and alignment within the firm is also important (Hodge, Anthony, & Gale, 1996;Womack, Jones, & Roos, 1990). Thus, the following hypothesis has been created: H1: SC planning has a positive impact on SC performance.

Risk and Reward Sharing (RR Sharing)
RR sharing refers to a mutual sharing of both the risk and reward elements among supply chain partners (Bowersox, Closs, & Stank, 1999;Min & Mentzer, 2004;Sundram et al., 2011). The three mutual dimensions of risk include the likelihood of a certain outcome occurring, the consequences, and the overall cause of the outcome (Jüttner, 2005). RR sharing between partners of the supply chain assists the partners in divvying up the risk and reward levels for aspects of technology, customers, and market-focused initiatives (Hall, 1999;Ritchie & Brindley, 2007;Sundram et al., 2011). For this reason, SC partners who participate in RR sharing will have a competitive advantage, thereby improving SC performance in the long run (Towill, 2005). Thus, the following hypothesis has been created: H2: Risk and reward sharing has a positive impact on SC performance.

Level of Information Sharing (IS)
IS refers to the level or extent to which critical and proprietary information is shared, or communicated, with partners of the supply chain, particularly in regards to information about the market, product, or customer (Li et al., 2006;Mentzer et al., 2001). Improving SC performance depends on both the quantity and quality of the information being shared. Specifically, making this information accessible and visible to the other parties of the supply chain facilitates more efficient and more accurate business decisions, which then can translate into a competitive benefit (Moberg, Cutler, Gross, & Speh, 2002). In this way, IS contributes to reducing the total cost of the supply chain in how it relates to performance (Gavirneni, 2006) by terminating the effect of fluctuation in customer demand (Fiala, 2005). According to (Stein & Sweat, 1998), when SC partners exchange information regularly, they can better identify the needs of the end customer, thereby resulting in a more efficient response to market change. Thus, the following hypothesis has been created: H3: Information sharing has a positive impact on SC performance.

Information Quality (IQ)
IQ describes the extent to which there is accuracy, timeliness, satisfaction, and credibility in regards to the exchange and flow of information (Li et al., 2006). Information sharing is important, but its significance on SCM depends on what information is being shared, when it is being shared, and how it is being shared, as well as with whom (Holmberg, 2000). Forslund & Jonsson (2007) have indicated that various IQ deficiencies affect the accuracy and, thus, practicality of the prediction, as well as its ability to influence SC operation. Thus, the quality of the information affects the ability of practitioners to make effective business choices (Soliman, Janz, Raisinghani, & Meade, 2005). This means that supply chain partners are responsible for the accuracy, timeliness, and overall adequacy of the flow of information in order to positively affect SC performance. Thus, the following hypothesis has been created: H4: Quality of information sharing has a positive impact on SC performance.

Supplier Relationship Management (SRM)
SRM is defined as the longstanding relationship with which to leverage the strategic and operational capabilities of each participating firm so that all involved can enjoy significant benefits (Li et al., 2006;Li et al., 2005). That is to say, a true supplier partnership encourages mutual planning and problem-solving efforts (Gunasekaran, Patel, & Tirtiroglu, 2001). Gandhi et al. (2017) have investigated the impact of supplier management on SC performance; their finding is that successful supplier management is directly correlated to a higher level of SCP. To achieve effective SRM, though, coordination is required between the supply chain partners. With this effective coordination, there can then be successful SRM, thereby ensuring a seamless flow between the supplier and the firm; this will, in turn, allow for the right product being available at the right time, resulting in the enhancement of SC performance (Sundram et al., 2011). Thus, the following hypothesis has been created: H5: Supplier relationship management has a positive impact on SC performance.

Customer Relationship Management (CRM)
CRM refers to the ability to create a longstanding relationship with customers; this includes treatment of customer complaints and the ability to, overall, boost customer satisfaction (Tan, Kannan, Handfield, & Ghosh, 1999). The ability of a firm to develop effective CRM will assist the firm in providing value to the customer, thereby gaining the customer's long-term loyalty through improved customer satisfaction (Cox, 2004). The ability to maintain good CR and attain valid and useful customer feedback is an important dimension of SCMP. Additionally, a firm's ability to respond to the needs of a customer by meeting demand through the creation of new products enhances a firm's ability to perform better (Gawankar, Kamble, & Verma, 2013a). If a solid customer relationship is in place, then a firm has the ability to offer the right product and services to the customer (Sundram et al., 2011). Thus, CRM enables the ability of a firm to re-tain customers (Ranjan, 2010), and this, in turn, helps improve a firm's performance. Thus, the following hypothesis has been created: H6: Customer relationship management has a positive impact on SC performance.

Supply Chain Performance (SC Performance)
SC performance refers to the extent to which the supply chain meets a customer's needs in terms of the products and services available and time of delivery of these products and services (Beamon, 1998;Li et al., 2002;Tarafdar & Qrunfleh, 2017). SC performance is based on factors used to determine the efficiency and effectiveness of an existing supply chain system. Parameters were determined in the literature review which can judge the efficiency and effectiveness of the supply chain; such parameters included customer satisfaction, sales, and profit.
In this current study, however, we have used other common SCP factors addressed in the literature: forecasting and material accuracy, on-time delivery capability, delivery reliability and consistency, precise supply chain cost knowledge and control, fast customer response, coordinated product flow direct from supplier to store, inventory management, rationalization, and responsiveness to changing requirements (Gandhi et al., 2017;Qrunfleh & Tarafdar, 2014;Tracey, Vonderembse, & Lim, 1999). Thus, the following hypothesis has been created: H7: Supply chain performance has a positive impact on a firm's financial performance.

Firm Financial Performance (FFP)
Performance measures reflect how the firm is performing about its objectives, mission, and values. These measures include conventional measures of performance for a business unit. From the literature, it has been shown that common FFP measures include return on asset, market share, return on investment, net profit, growth in net profit, sales, growth in sales, productivity ratio, total cycle time, total cash flow time, cost savings, inventory turns, net income before taxes, gross margin, quality performance, inventory management performance, and financial liquidity. There are non-financial measures as well, including overall competitive position, the present value of a firm, innovation performance, market share, performance, and quality improvement. However, the FFP in this current study was measured using indicators of financial performance like profit, revenues, and return on investment (Beamon, 1998;Chen & Paulraj, 2004;Gawankar et al., 2013b).

Research Design and Methodology
The main purpose of this study was to investigate the relationship between different SCMPs and SC performance and the relationship between SC performance and FFP. The primary study instrument used for this research was a validated questionnaire. A summary of the survey questions is shown with the summary of statistics in Table 2.

Data Collection
A total of 3500 surveys were mailed, and the response rate was approximately 5.6%. The data analysis is based on the 196 usable questionnaires. Additionally, a series of interviews were conducted with different supply chain managers to ascertain information regarding the problems that supply chains face, as well as to learn which practices are most important for the improvement of supply chain performance in the Kingdom of Saudi Arabia.

The Sample List
The sample firms for the study were randomly selected from the database of the three main Commercial Chambers of Saudi Arabia (Riyadh, Sharqia, and Jeddah), which lists different industries. The targeted respondents were senior executives (i.e., GM, CEO, plant manager, SC manager, purchasing manager). Most respondents (24%) were general managers, and more than 39% of the firms represented the basic materials industry. In terms of number of employees, almost 40% of the firms were in the category of 101 -200 employees. Almost 65% of the respondents had been in their current firm for at least five years. Over 88% of the sample had earned a bachelor's degree. Male respondents comprised approximately 92% of the sample. The details of the demographic data are shown in Table 3.

Measurement Scales
Survey questions and descriptive statistics for each survey statement are presented in Table 2. Each statement required responses based on a 6-point Likert scale (1 = Strongly disagree to 6 = Strongly agree). Questions PLN1 to PLN5 were used to measure SC planning practices; questions RRS1 to RRS3 were used to measure RR sharing practices; questions IS1 to IS3 were used to measure the level of information sharing between supply chain partners; questions IQ1 to IQ5 were used to measure the quality of information being shared between supply chain members; questions SRM1 to SRM3 were used to measure supplier relationship management practices; and questions CRM1 to CRM5 were used to measure customer relationship management practices. SC performance was measured by questions SCP1 to SCP6. Questions FFP1 to FFP3 were used to measure the FFP as compared to its competitor companies (1 = much worse; 6 = much better).

Validity and Reliability of the Instrument
The validation process for the survey instrument included two steps: content validity and reliability. The literature review and in-depth interviews conducted with business executives and researchers established the basis of content validity, showing that the items measured what they were purported to measure. Reliability was measured by Cronbach's alpha. The lower limit of 0.7 is considered acceptable for established scales (Nunnally, 1994). Cronbach's coefficient alpha is shown in Table 3. American Journal of Industrial and Business Management

The Results of the Measurement Scales
The results of the measurement scales are shown in Table 2. All scales have Cronbach's alpha value of 0.7 or higher. Table 2 also reports the mean value and standard deviation of each item in the survey.

Correlation Analysis
The next step was to conduct a correlation analysis between variables. Table 4 presents the bivariate correlation between SCMPs, SC performance, and FFP. As Table 4 shows, each construct shares a greater variance with its own measures than with any other construct. This reveals that each construct is more closely related to its own measures than to those of other constructs, thereby confirming the discriminant validity (Fornell & Bookstein, 1982). Table 2 shows that the mean score of SC planning, IS, and CRM is much higher than other SCMPs, indicating significant use of those practices. At the same time, RRS and IQ mean scores were the lowest, indicating a lack of use of those practices.

Results
We used multiple regression to test the relationship and the statistical significance of the parameters using a t-test in the structural model (Chin, 1998). The variance explained (R 2 ) and the significance of the path coefficient indicates the quality of the model (Chin, 1998). Table 5 shows the result of the model. The R 2 value was 0.929, indicating that the model explains a good amount of the variance in SC performance.

Findings Related to Hypothesis and Discussion
In this section, we discuss the results shown in    We hypothesized that SC planning has a positive impact on SC performance. The results show that H1 is strongly supported and statistically significant, as shown by (β 0.365 = ***; t-value = 8.086). This result provides empirical evidence for the impact of SC planning on SC performance.
We hypothesized that IS has a positive impact on SC performance. The results of the study show that H3 is strongly supported and statistically significant, as shown by (β 0.209 = ***; t-value = 4.818). Furthermore, this study shows that sharing information between SC members leads to improved SC performance. Continuous communication between firms and their suppliers leads to real-time inventory, which helps suppliers better plan their delivery schedules, thereby improving SC performance (Sundram et al., 2011).
We hypothesized that SRM has a positive impact on SC performance. The results of this study show that H5 is strongly supported and statistically significant, as shown by (β 0.238 = ***; t-value = 4.887). The results of this study indicate that firms need to develop mutually beneficial relationships with suppliers and view their suppliers as partners. That is to say, firms and their suppliers need to work together in terms of planning, coordination, and forecasting in order to positively impact SC performance (Gawankar et al., 2013b).
We hypothesized that CRM has a positive impact on SC performance. The results of this study show that H6 is strongly supported and statistically significant, as shown by (β 0.249 = ***; t-value = 5.652). If a firm draws up a customer-driven objective and all members work toward achieving customer satisfaction, this will improve firm performance (Chow et al., 2008).
We hypothesized that SC performance has a positive impact on FFP. The finding of the study shows that H7 is strongly supported and statistically significant, as shown by (β 0.767 = ***; t-value = 16.652).
The findings related to H2 (the relationship between RR sharing and SC performance) and H4 (the relationship between IQ and SC performance) both indicate a negative relationship with SC performance, as shown in Table 6. These results disagree with Sundram et al., 2011;Zhou & Benton Jr. (2007), whose re-sults showed that the quality of information has a significant positive influence on performance.

Implications, Limitations, and Future Research
This section discusses the implications of this study for practitioners. Additionally, this section presents the study's limitations and explores what opportunities exist for future research.

Implications for Practitioners
This study has significant implications for practitioners, giving them valuable information that can help them adopt a suitable strategy for improving their performance. This study finds that SC planning, IS, SRM, and CRM all have a positive 4 on SC performance. These findings suggest that an organization needs to keep implementing these practices to improve SC performance. At the same time, manager should particularly focus on implementing RR sharing and IQ practices. Additionally, the results of this study show that respondents do not currently apply the practice of sharing risk and rewards but that they should; the recommendation is that managers should activate this practice, especially in regard to sharing the research and development costs with other supply chain members so as to improve SC performance.

Limitations and Future Research
There are several limitations to this study, which could provide opportunities for future research. First, this study examined the impact of different practices-SC planning, RR sharing, IS, QIS, SRM, and CRM-on the SC performance for firms of different industries only in the Kingdom of Saudi Arabia; in the future, these effects could be studied in a specific industry, such as retail or the service industry. Second, researchers could study different moderators to find out what those moderators' impact (strengths or weaknesses) is on the relationship between SCMPs and SC performance. Third, this study focused on firms located in the three main regions of Saudi Arabia; future research could include other areas as well. In addition, this research employed perceptual performance measures to measure return on investment, revenue, and profit. Future studies could use actual numbers to better quantify the benefits of this context.
