In the present scenario, supply chain management (SCM) is significant for business to optimizing the operation related to supply chain (SC) and enhances the efficiency of SC with a higher speed which is important for delivering products to the consumer at right time (Christopher, 2016; Tang and Musa, 2011). In this regard, the present report discusses the literature about the SC and practices adopted for material management for smooth operation of the business.
For this purpose, different supply chain practice like supplier selection, sustainable supply chain (SSC) and different inventory management approaches which are collected from various academic journals and books. Apart from this, for gaining a deeper knowledge of SCM primary research on Walmart’s SC activities is also carried out with the help of the questionnaire method. Hereby, a report is also constructed for analyzing the consistency between primary and secondary data.
SCM is helpful for delivering the high excellence products at the right time to the end users because it ensures the effective management of SC activities (Cao and Zhang, 2011). In this context, the Just In Time (JIT) inventory management approach identifies mistakes in the final product and helps to fix that error faster with the help of integrated SC (Wild, 2017). Similarly, it reduces wastages in the inventory because it focuses on the storing of a low volume of the products (O’Grady, 2012).
It decreases the inventory management cost because of a low volume of material are easy to handle. Thus, this approach enhances management efficiency to handle the inventory in a cost-effective manner. At this juncture, if the demand of the particular product is instantly going upwards then the Safety Stock Inventory (SSI) approach is helpful because it focuses to ensure the few amounts of stock for the unexpected demands (Van Kampen, Van Donk and Van Der Zee, 2010). For instance, Walmart, a multinational retailer faces issue related to stock out due to the poor focus on the inventory management (Rosenblum, 2014).
In this context, Bertazzi, Bosco, Guerriero and Lagana (2013) asserted that the stock out is the most difficult situation for the business because it decreases the sales and vanished the goodwill. Therefore, for a retailer selection of inventory management system is most important to elevate the sales and generate a high financial output of the business with a productive inventory management. On the other hand, uncertainty in the environment also affects the approach of just in time because it creates the barrier in transportation in the products and suffers the organization from the unavailability of the stock (Beutel and Minner, 2012). Therefore, the SSI method is helpful for ensuring the continuity in the supply chain operations by preventing the stockout issue.
In the present scenario, the sustainability of supply chain is significant for enhancing the effectiveness of supply chain (Barney, 2012). In this regard, the sustainable supply chain (SSC) has a low harmful impact on the environment because it fosters the minimization of the CO2 emission from the supply chain activities like transportation (Carter and Liane Easton, 2011).
For example, UK’s one of the top fashion retailer (Walmart) targets to remove the discharge of hazards chemical in the supply chain activities and ensuring the sustainability of supply chain (Sustainable Brands, 2018). In this context, Walker and Jones (2012, p. 15) asserted that the sustainable supply chain diminishes the negative consequences of a business on the environment, society and the economy by considering the factors which affect the supply chain.
Thus, management focus on the sustainable supply chain for avoiding the hazards in business activities and ensures the business growth. For instance, Australian government set a standard for reducing greenhouse emission in Australia through the vehicles and the commercial firms because it continuously going at a high stage which is more extensive (Jericho, 2018; Parliament of Australia, 2018). By imposing these policies, Australian government make sure the harmful emission of greenhouse gasses in the environment reduces and business are gets aware for the minimization of harmful emission in the environment by business activities.
According to several studies, supply chain management (SCM) is crucial for a business to improve the quality of end products because it truly depends upon the quality of raw material supply by the suppliers (Barney, 2012). Apart from this, the selection of a supplier is playing a vital role in the development of sustainable supply chain because the ethical behaviour of supplier also affects the society and environment (Grover, Grover, Rao and Kejriwal, 2016).
In this context, Molamohamadi, Ismail Leman and Zulkifli (2013) mentioned that the supplier selection process required a huge amount of financial resources of the organization; thus, the management focus on the supplier selection is significant to prevent the firm from the financial losses. If the firm selects those suppliers who are highly valued in the environment protection criteria then it increases the probability for providing advantages to the firm else the firm faces many harmful circumstances like negative publicity, financial losses etc.
For example, low focus on the supplier selection adversely influenced the brand reputation of UK’s retailer Tesco because suppliers supplies the horse meat patties instead of beef patties which consequent in the financial losses of Tesco (Fletcher, 2013; Lawrence, 2013). It reveals that a firm should focus on the selection of those suppliers who take parts in the progress of supply chain in the direction of sustainability. With the help of effective supplier, a firm ensures the growth of the business.
The supplier selection is also important for effective material management in the regular business operation through supplying right material at the right time with required quantity from the right sources at the affordable price (Bai and Sarkis, 2010). If the supplier fulfils all the needs then it helps for turning a conventional supply chain into a sustainable supply chain. In this regard, Qu et al. (2012) asserted that the material management is also significant for streamlining the production process of a business because it organizes the storage,
flow and supply process in an effective manner. On the other hand, technological advancement also helps in the collaboration with the supplier and helpful for a firm to get the right material at right time (Jean, Sinkovics and Kim, 2010). However, when an organization deals with a large amount of supplier then it becomes hard to balance among suppliers. For example, in the case of Walmart, large numbers of vendors enhance complication of management for the allocation of profit interest in suppliers (Shin and Tucci, 2015).
In this context, Sundtoft Hald and Ellegaard (2011) indicated that poor allocation of profit interest in the supplier enhances the dissatisfaction in them and may result in the failure of supply chain practices. It shows that allocations of profit interests in the suppliers are important for dealing with supplier effectively. Therefore, for effective management of manufacturing operation and elevates the productivity, the supplier selection and profit allocation are considerable tasks for the management.
Primary research on the supply chain of Walmart
The primary study has been carried out by gathering information from managers of Walmart. Since the purpose of the study is to evaluate the supply chain practices so the respondents from production and sales managers are targeted. They are selected on the basis of purposive sampling by keeping into mind the constraint related resources and time. Furthermore, the questionnaire method has been selected wherein closed-ended questions have been added in the easy to understand language. Apart from this, thematic analysis has been carried out on the basis of a questionnaire. In this regard, separate themes have been constructed along with the frequency tables which provide the evidence of the collected data.

Conclusion
On the basis of the above report, it has been concluded that effective management of SC is most crucial for a business to ensure business growth. Hereby, SCM is also important for creating a better relationship with customers as well as with the clients of the business. Apart from this, on the basis of primary research, it can be concluded that by using a different approach like integrated SC, technological advancement and SSC, the efficiency of SC is increasing.
On the other hand, effective SCM reduces the harmful impact of commercial activity like CO2 emission in the environment which helps in the protection of the environment and ensures the long-term growth by elevating the competitive edge. It further helps in retaining more customers and loyal suppliers. At the same time, it can be also concluded that by selecting an appropriate supplier a firm enhances the effectiveness of production operation. Therefore, consideration on SCM is the most significant task for the management of an organization.
