Usage of data analytics in improving sourcing of supply chain inputs

One of the most remarkable features in the 20th century was the digitalization of technical progress, which changed the output of companies worldwide and became a defining feature of the century. The growth of information technology systems and the implementation of new technical advances, which enhance the integrity, agility and long-term organizational performance of the supply chain, can distinguish a digital supply chain from other supply chains. For example, the Internet of Things (IoT)-enabled information exchange and Big Data analysis might be used to regulate the mismatch between supply and demand. In order to assess contemporary ideas and concepts in the field of data analysis in the context of supply chain management, this literary investigation has been decided. The research was conducted in the form of a comprehensive literature review. In the SLR investigation, a total of 71 papers from leading journals were used. SLR has found that data analytics integrate into supply chain management can have long-term benefits on supply chain management from the input side, i.e., improved strategic development, management and other areas.


Research background
The digitization of technical innovation in the 20th century, which changed the output of companies all over the world, was one of the characteristics of this time. As a result of digitization, this has influenced both businesses and the entire economy. The collection and shared knowledge through time is a key component in driving progress and innovation in today's fast-changing industrial environment, particularly in the service industry. Therefore, a digital transformation in the service industry is necessary to focus on the drivers of technology for exponential development, drivers of social expectations, the economic environment and business value demands (Travaglioni et al., 2020).
Management of the service supply chain (SCM) is often used in manufacturing enterprises, but is seldom used in the service sectors. In recent years, the importance of the service industry in the global economy has risen considerably. Along with the fast growth of the service industry, a substantial share of the labor force has gone to the service sector from the manufacturing sector.
The literature on supply chains has been restricted despite the considerable quantity of scientific work in the supply chain management (SCM), which mostly concerns the establishment of supply chain networks. In recent decades, developed economies in service-oriented organizations, in order to better meet the requirements of customers, have undergoing a transformation. Service-specific SCM and attempts to address the functional differences between manufacturing and service sectors have been created.
The services supply chain, according to Schnetzler, Sennheiser and Schönsleben (2007), is a set of activities built through the use of information, content and money flows to satisfy the customer's need. In particular, the management of service supply chain is the collection of processes and activities connected to services, including inter-organizational supply chain networks, service development and other activities as well as the value chain (Attaran & Attaran, 2007). A effective service supply chain must include best-of-breed products and services, while incorporating a wide spectrum of players (Joshi, Sharma, & Rathi, 2017).
The importance of services in the financial prudence of a country underlines the necessity for greater research into services. The service industry is increasing rapidly in emerging nations (Thakur & Anbanandam, 2016). Suppliers, consumers and other support organizations establish a network which handles the resource transactions required to provide services, transforms these resources into forms of use and provides support and core services for clients (Nagariya, Kumar, & Kumar, 2020). As a key engine for economic growth in many industrialized nations, the services economy must be seen as a service supply chain management (SCM) ( Digitalization has evolved as a new phenomenon in our contemporary day with a difficult and dynamic environment and a competitive corporate world which affects many parts of life across the world. In the past, more than 90% of internet users have conducted online purchases, with about 40% using technological technologies to assess enormous volumes of information. In addition, the Internet of Devices has already made it possible to link 26 billion things until 2020. Digital distribution networks can be distinguished by the growth of information-technology systems and the adoption of new technical breakthroughs that increase the integrity, agility and long-term organizational performance of the supply chain. The DSC will employ state-of-the-art technology, focus on consumers, decrease costs inside the company and produce increased organizational value. It is also important to address problems concerning DSC installation, optimization and development, as well as new management techniques to increase customer satisfaction. Although practitioners have studied these challenges extensively and DHL and DB have progressively dealt with them (e.g. DHL, DB), DSC is still in its early stages in academics (Büyüközkan & Göçer, 2018). Indeed, the notion of DSC has expressly been confined to a small number of studies and a wide variety of study areas still contain literature on this issue. Prior study focused mostly on the technological drivers of Industry 4,0 and DSC, including the Internet of Things (IoT), cloud computing (CC), Big Data (BD), and UAVs. Likewise, cloud computing is still being studied in the supply chain in digital technology only in theory and practice, as was the case before .

Figure 1 Evolution of big data with time
The few empirical study on this issue focused on characteristics that influence cloud computing adoption and the impact of cloud computing on the supply chain. Cloud computing, according to studies, helps to extend the supply network as well as to make supply chain operations in general more effective and responsive. (Bruque and Maqueira, Moyano-Fuentes, 2019).

Research question
− What is the effect of data analytics of supply chain on sourcing of inputs within the context of service supply chain?
− What is the most effective method in data analytics that can uplift service supply chain?

Research significance
The research has significant contribution in theoretical and practical perspectives.

Theoretical importance
All the prevailing theories regarding supply chain management are concerned towards conventional supply chains. In the prevailing conditions of big data, the present research will provide a significant addition to the theory of supply chain management.

Practical importance
Many industries are striving to manage their supply chains amid changing scenarios. The research will provide significant implication for these industries to include data analytics for optimization of their supply chains. A conventional supply chain is a network of systems, processes, and organizations that are involved in the production, delivery, and distribution of valuable commodities and services to their ultimate users . While, Supply Chain 4.0 reorganizes supply networks at all levels-design, design, production, distribution, consumption, and reverse logistics-to create a more efficient and efficient supply chain. These technologies, which were first launched in the twenty-first century, are primarily used by high-revenue firms that are pioneers in supply chain management and at the forefront of innovation (Zekhnini et al., 2020, Ghobakhloo, 2020.
In order to manage the incompatibility between supply and demand, for instance, IoT-enabled exchange of information and big data analysis might be utilized. The present literary research will examine contemporary ideas and concepts in the area of supply chain 4.0 and try to find the gap in literature review.

Supply chain
Today, corporate digitization shifts the way company works as well as the financial, information, labor and material flow management needs. In the viewpoint of involvement in global supply chains. (MIETHLICH and VESELITSKY, 2020) developed the idea of country digital developments in supply chain management (SCM). Digital SCM investments guarantee full, reliable information is available to execute logistics at all levels in an effective manner. It promotes the growth of market relations, secure the operation of national structures, and contribute generally to good qualitative improvements in the country's living standards.
These are also based on transport systems, platforms and networks, as well as physical networks.
Supply chains may typically be divided into three parts, namely procurement, manufacturing and distribution. Supply chains are part of the logistics idea, but are separate from it. As part of the continuous and integrated process, supply chains include sourcing, manufacture and distribution operations (Tay, 2015). In its integration into all essential business activities, the supply chain considers a logistical "place of origin to point of consummation." This involves process alignment and harmonization, electronic data exchange and the establishment of strategic relationships in the long term. Manufacturing processes have begun to acquire scalable flexibility, from huge stocks to low speed and postponed product setup, offering maximum value for money with high levels of flexibility in combination with demand management methods. The effects of new technology on distinct supply chain processes are identified by (Zekhnini et al., 2020) that SC4.0 is an advanced framework with interconnected processes, from unconnected applications to a wide-ranging, coordinated and effective interaction between SC stages.

Supply chain management
The performance of the supply chain must be separated into various components to analyse how overall performance is affected by the use of data analytics. Supply network management is based on an acceptable definition of the word "supply chain." In a 2001 article, Mentzer, DeWitt, Keebler, Min, Nix and Smith conducted a literature analysis on the issue of supply chain and supply chain management terminology.
The performance of a supply chain is harder to quantify since it has a variety of key performance indicators which indicate the efficiency of the supply chain. The study paradigm (Gunasekaran, Patel and McGaughey 2004) divides three kinds of processes: strategic, tactical and operational.
There are several kinds of supply chain management processes and each contains several activities in these four categories: planning, procurement, production and delivery. SCOR, a 1996 PRTM model, is presently owned by PricewaterhouseCoopers LLP (PwC). The APICS Supply Chain Council is the leading supply chain framework in the world and states that the SCOR model links business processes, performance measures, practices and skills to one unified organization. Four times more likely, according to Benton, Zhou, Schilling and Milligan research, employees have the competencies needed if their business matures digitally (2011). The digitization means that workplaces are undergoing enormous shifts. The adoption of new concepts on intelligent production, intelligent contracts and intelligent services together with information sharing and information automation would drastically transform finance, sales, maintenance, the supply chain and logistics (Eller, Alford, Kallmünzer & Peters, 2020).
They will have extensive effects on jobs and jobs, as well as on the workplace and the environment.
The increasing complexity of working procedures pushes employees to learn new capabilities.
Automation, networking and interdisciplinarity need the development and acquisition of many disciplinary skills. These specific skills are technological competencies that are based on fundamental capabilities in ICT (Iomäki, Kantosalo, and Lakkala, 2011).
Additional skills, including cloud computing, data security and mobile technology These abilities are more behavioral and relate to employee incentives and traits. It's far more personal, interpersonal, and not almost as useful. Some of SC's skills in digital transition include leadership, communication, decision making, management of business processes, critical thinking and negotiation. This challenge to digitalize the supply chain occurs at various levels. As digitalization increases, it is more necessary for organizations to develop job descriptions that meet the growing requirements of SC digitization. They must also be able to help their personnel develop and improve their skills in order to fulfil their tasks. Human resources in sectors such as logistics and supply chain management are inadequate, which requires considerable recruiting focus. To be able to grow, people need to comprehend the different changes that have happened due to digitization to SC operations. Now that institutions need to train in the new scanning criteria for SC, they are obliged to tackle this problem. In order to complete digitalization, IC and Digital media are contributing to SC digitization, thus employees need different information, aids, defiance, competences, methods and responsiveness (Ageron, Bentahar, and Gunasekaran, 2020).

Supply Chain Data Analytics
Everything inside the SC is crucial for financial concerns, information exchange and decisionmaking. The West introduced BI in the mid-20th century to enforce this competence. BI is a technology that supports business processes through data analysis. Effective data collection and analysis may be done using BI technologies that provide a library of analytical solutions. All aspects of the BIA process include data extraction and transformation, data base management, database mining and recovery, data reporting and visualization and multi-dimensional analysis.
Processes like as OLAP are extremely essential when it comes to BI. Companies using BI methodologies may calculate their worth in real time, including stock volume, delivery costs, products costs and inventory turnover rates.
Organizations can make better decisions while carrying out business activities. Minimizing overall expenditures and increasing total sales is ensured via improved management and SC flexibility for customers and suppliers. A BI system may help an enterprise achieve a SC balance, which enables more cash flow. This assistance will allow firms to do data analysis in real time and develop predictive models that promote customer expectations, supply chain activities and the evaluation of supply chain participants with particular emphasis on suppliers. A high degree of integration in the supply chain allows company to gain a competitive edge and benefit all stakeholders, particularly in a dynamic and challenging market.
BI methods are used to the SC for SC performance analysis including the integration of various SC management operations such as planning, procurement, manufacture and delivery. The SCA aims to collect huge quantities of real-time data generated by the SC system and to utilise this data to provide meaningful information for SC decision-makers (Sahay and Ranjan, 2008). The figure on the right shows how BI supports business activities. In the first phase, data from different departments are assigned to four main processing stages. Extraction, cleaning, processing and loading. The business analyst then transforms the data into usable information for end users while entering the data in a data warehouse. Figure 1 is derived from the source in the previous section (Sahay and Ranjan, 2008). BI's four components are customer support, market research, distribution, profitability and inventories. These are crucial to comprehend and generate the data needed to manage a company. Significant information sources are ERP, SCM, CRM systems, customers, suppliers, manufacturing processes, new product testing and development, market prediction, demographic customer distribution, and other data sources. Companies are interested in Big Data Analytics and predictive analysis after the growth of BI and IT and complex SCs in real time to cap all of this.
In a poll which questioned U.S. businesses to find out what sort of corporate database they wanted (they may utilize their SCA applications) 57% of them opted for a warehouse, while 43% chose a separate SCA data warehouse. The technique of using vast volumes of data in quantitative and hypothesis investigations is known as predictive analysis of big data. Predictive analysis using BI is used for SCA operations involving the estimation of predicted inventory quantity, failure rate, time for failure, quantity of road commodities, customer orders and requests, and suppliers' strategies. SCM Big Data Predictive Analysis may enhance SC performance by forecasting the volume of future business by analyzing previous data (Waller and Fawcett, 2013).
The term 'supply chain 4.0' refers to the physical and technical integration of systems across a network that increases production, organization, and profitability characterized by independent action, widespread integration, diverse automated services and the capacity to react in context to the needs and requirements of customers (Shahin, 2010). The phrase "Industry 4.0" was used to describe in particular the fourth industrial revolution and the integration of intelligent systems in supply chains. Such systems are helpful in producing and manufacturing for business and the military, highlighting and safeguarding the worldwide networks that share models and information. The impact of the new digital era on the Fourth Industrial Revolution has led to the implementation of innovations required for digitization of industry, information and communication technologies, and the Internet of Things (IoT) cyber physical system (CPS) architecture, for production logistics and SC applications. (Ghobakhloo, 2020).

Risk management
Six important features of SC4.0 that are meant to include all suppliers and customers in the supply chain . The internet of things (IoT) seeks, by incorporating sensors, actuators and other devices that gather, transmit, and analyses data, to expand and link physical items to the internet. In SC, this technology links together business and web applications (like social media) and equipment, goods, materials and persons, thereby enabling the creation of an intelligent network spanning all industrial operations and consumers and suppliers. Cyber-physical systems contain digitally produced equipment, storage systems, and manufacturing facilities that are fully Furthermore, the technology allows organizations to enhance their flexibility, productivity, dependability and reaction. Moreover, firms may reduce the bullwhip effect and expenses associated with SC operations by facilitating a rearrangement of the entire operation in real time.
In describing a technique for incorporating sensor-based quality data into supply chain event management in received many favorable responses. The utilization of sensor data in combination with event-driven material flow management can contribute to more stable inventory levels through a discrete event simulation. Finally, as previously indicated, sensor data may be utilized to improve quality monitoring of transport activities within car supply chains (Ali and Aboelmaged, 2021).

Digitization of supply chain
Digitalization has been helping to boost the expansion of the computerized industry. By using digitalization capabilities, a competitive advantage may be gained by reorganizing existing assets, adding new assets or integrating assets from other sources. Therefore, digitization can emphasize content, in which the industry determines what concept to use and digitality enables that concept to be implemented; performance indicates that reporting and collection times must be reduced; usability shows that delivery methods need to be improved, for example the dashboard context.  In order to assess the potential of the use and analysis of big data, an examination of the literature will be conducted. The main applications used to get access for this research will consist of the WorldCat.org database, which is associated with Tilburg Universität, and Google Scholar. The following keywords identify related articles: big data; analysis of data, analysis of data; data science; analysis of companies; data integration; management (supply chain); business processes; and policy making. In the order they were asked, this thesis answers the research questions; as a result, it is organized accordingly: Initial study on the basis of existing literature will be carried out to identify recommended parameters such as data, big data, analysis of the data, supply chain, and supply chain performance. In the following stage, a review will take place of different kinds of data involved in supply chain management to report on the sorts of data important and crucial to the management of supply chain.

Sample & population
Population for this study include all research journals having papers with SCM and data analytics in topic.

Data collection method
In order to assess the potential of the application and analysis of big data in supply chain management, especially in the procurement of inputs, and raw materials, a full literature research will be undertaken. The major way of accessing vital material is Google Scholar and other comparable programs. Big data analysis, data analysis, data science, business analysis, data integration, supply chain (management), business processes and decision-making will be one of the themes of these articles. These are the topics of research handled in the following order in this thesis: In order to determine the recommended variables 'data,' 'big data,' 'data analytics,' 'supply chain' and 'supply chain performance,' current literature will be reviewed, as follows: Thereafter, research will be carried out in order to report on the data kinds that are critical and vital for supply chains management in the various forms of data involved in supply chain management.
The focus will be on the literature discussing techniques for analyzing data that can have an important impact on the supply chain process after determining the definition of the variables and the type of data involved. This will improve the level of insight within the supply chain process and the variables will be determined.

Ethical consideration
Following the selection of the most relevant data analysis tools, the emphasis will shift to the integration of data into decision-making and company operations. Last but not least, data, dataanalysis tools, and business procedures will be brought together to provide an overview of how firms might eventually apply these elements to improve their performance in the core supply chain operations sector.  Table 2. Table includes possible applications of strategies to increase supply chain performance and to which these techniques could correspond the primary supply chain process.

Integration of data from several sources into a process of decision making
Back in 1974, Galbraith explored organizational design through an information processing perspective. He claimed that uncertainty demanded further information processing to reach a higher level of performance: "The greater the uncertainty in the task the larger the quantity of information must be processed by decision makers in order for a given level of performance to be achieved." He also noted that ambiguity hinders an organization's capacity to prepare or decide in advance. Through greater planning and cooperation, companies can decrease this unpredictability.
The diversity of data is one of the distinguishing properties of data and especially of large data. If all these facts are properly incorporated in decision-making and management, they may be converted into information. If the integration of systems and data from automation and process simplification inside the company is done with expertise, it will enable decision-making to be supported (Kościelniak & Puto, 2015).

Systematic literature review on data analytics in SCM

Block chain
The confluence of certain elements lately strengthened the demand to utilise data analyses in supply chains (Ittmann, 2015): 1-increasing data volume in the supply chain; 2-decreased data storage costs over recent years; 3-powerful hardware that can speeding up data analysis; 4-mobile data continuous access; 5-powerful tools that simplify data work; and 6-ways that can visually display huge amounts of data (advanced visualization). The information available in the supply chain mostly relates to customers, sales, markets, service levels, demand predictions, inventories, Big data allows firms to assess their suppliers better and regulate the procurement process (Sanders, 2014). Big data also enables firms to simulate their supply networks. Simulation enables bottlenecks to be found, the production process may be practically performed at multiple sites and prototypes examined (Kynast & Marjanovic, 2016).
Big data may improve supply chain performance by enhancing the visibility, resilience, robustness However, it is worthless that review publications are not further explored as we analyse research contributions in the literature; the "review" category is included in Figure 5 to help provide more information. In addition, the categories "knowledge management," "agility" and "algorithm development" are not explored further as fewer than 5 percent of all articles are included.

Development of strategies
It would be a strategic choice of management to employ Big Data Analytics in a firm. Management commitment has a favourable impact on the acceptance of big data analysis by a firm (Gunasekaran et al., 2017). Big data analytics enables the management to obtain dynamic data-based analysis and make the supply chain more competitive . Big data analytics can help coordinate and regulate the planning, decision making and supply chain preparation, alertness and flexibility of the supply networks in issue (Mandal, 2019). The topic of big data value generation was not widely explored in the literature of supply chain management. Brinch (2018) therefore examined value discovery, generation and capture in the corporate supply chain utilising big data analysis.
All the advantages mentioned are insufficient actual research which applies big data analytics to supply chain management, therefore it is not possible to choose an educated strategy merely by comparing different approaches (Kache & Seuring, 2017). Investing money into the gear and software needed to implement Big Data Analytics might influence supply chain strategy. With regard to training, our education system can teach a number of data scientists, but the management capabilities of these data scientists have often been overlooked (Carillo, 2017). Consequently, turning the data provided into relevant information to minimize supply chain risks is still a barrier In a further research, Hofmann (2017) shows that the speed of big data may be utilized to decrease the bull wheat effect in supply chains (raising the degree of safety in upstream echelons). Working with supply chains of omni-channels creates a great deal of data from many sources. Big data analysis can make sales projections in various channels more accurate and build optimum delivery strategies to save transport expenses (Lee, 2017). Sharing data using a big data architecture may minimize uncertainty costs in a supply chain in another instance (Liu & Yi, 2016).

Sales and marketing
In addition to predict demand, large-scale data analytics may help marketing managers analyses existing product sales patterns. For example, product reviews may be more readily approved in various studies, which may influence sales performance (Li et al., 2016). When Boone and colleagues investigated the sales enhancement effects of big data analysis, they observed that The study of social media information can help supplier chains to increase the

Conclusion
This thesis, as described in the introduction, aimed at gaining a better understanding of how organizations may successfully integrate and use data analytic techniques in order to improve supply chain performance. It has become clear that supply chain management teams face enormous quantities of different types of data across the supply chain that must be efficiently managed. Data analysis approaches must be utilized together with a comprehensive and goal-oriented thinking in order to extract (commercial) value from this data. This needs analytical thinking inside the organizational units to recognize and analyses prospective problems efficiently, with the aim of ultimately enhancing business processes. Employing professional data scientists with know-how in quantitative analytical methodologies and functional business understanding may make this approach easier and more efficient. In addition to developing solutions that have good repercussions on the business's internal operations, companies that rely on efficient supply chain management must work with upstream as well as downstream connections in the supply chain process to achieve maximum performance advantages. The "next link" in the supply chain can be better prepared to address future demand variations through the exchange of customer demand data and forecast analysis. This will result in enhanced performance both for individual enterprises and for the entire supply chain and in better performance for the entire supply chain. Business areas such as supply chain management are only a few instances of how data analysis may improve the operational environment, if not completely transform it. The fact that more than one firm participates in the whole business process is one of the reasons why this subject is particularly significant to the SCM sector. It is therefore highly attractive to seek for fresh and inventive approaches to increase the organization's performance considerably. The digitalization of society as a whole is another crucial element to consider. More and more information is generated and made available to organizations every day; nevertheless, the most essential component is the capacity to react when it is received on this data. Implementing data analytic techniques in business processes together with competent human resources to analyses the increasing amount of information will not only provide a better overview of the company, but will also help decide on the way business processes work, which can improve the overall performance of the company.

Challenges
Despite the advantages of Big Data for enterprises, many organizations still haven't widely used Big Data; this might be owing to the high initial cost of integrating Big Data that requires a significant initial investment. Management assistance is vital if a large data analysis system is to be installed successfully. An initial cost-benefit analysis of large data in the way it is utilised in the long run is a very tough assignment. It's not easy for companies with fewer transactions per day to find out if the big data analysis is useful, as is the case with many small firms. The fact, that traditional data analysis methodologies are not possible to be employed for information analytics since they are created by firms such as Amazon, Walmart, Google and others. Whereas in certain companies, the V features of Big Data are more doubtful, there is no guideline to assist management in convincing that the present data is appropriate for the establishment of a Big Data Analytical Framework.
A key difficulty is where to search for valuable data, how to acquire it and what techniques are needed in order to obtain it. Another difficulty is that vital information might be separated accidentally from the rest of the easily available content. Analysts must be aware of the information they wish to remove from the data and must be able to answer any queries they have concerning the information they can access. Another problem is to identify the most effective way to respond in the best possible way, while still costing considerable time and money. As companies adapt to the speed of technological progress, the demand for employees with an education in analysing huge volumes of data is rising. In addition, it is a challenging effort to build confidence between data analysts and management. Most systems initially are resistant to change, therefore assistance of superior managers is essential to adopt data analysis results in order to enhance the system.
It is likely that because traditional computers can only store and accurately analyse enormous amounts of data, a computer's Central Processing Unit (CPU) will be a barrier to Big Data Analysis. However, the accessible data are not always full and consistent; sufficient cleaning and integration procedures are thus necessary to make the dataset analytical.
The fifth "V" to the concept of vast data refers to the value derived by a large-scale data study.
Unfortunately, there is also a chance of hacking whenever there is a potential for profit.
Information security may be a challenging task when applying large-scale analyses within companies. A huge volume of information increases the likelihood of sensitive and valuable information in the system, therefore increasing system vulnerability and the risk of theft being able to access it (Spanish, 2014).
The most appropriate type of decision-making data for most of a system might also be determined as a challenge. For higher accuracy, not every choice is made using all the information available in a system. They determine which part of a data set to be used and what information should be included in the report based on the expertise and experience of the data analyst. It is also a regrettable truth that the intended audience may not necessarily create big data that are easily accessible. Although Twitter has an enormous number of contents, not everybody on a community has a Twitter account, like an example. In consequence, a portion of the community generates a huge number of information while the other half does not produce any of the data in a dataset. This fact emphasizes statistical uncertainty on a consistent basis such as skewed data.
If the results of a not-real-time data analysis are used for real-time data, the results of the analysis may differ considerably from those of the historical data to those of the real-time data; for example, the original premise of the prediction study is that the "future is past" could not be accurate.
Furthermore, if data shows cost-and time-effectiveness of a transportation route (and many organizations have access to this data), it may start to be used by other firms in the same way. The demand for the above-mentioned technology may be rising and may lose its attraction both in cost and in time.
Another long-standing and ongoing problem is the inability to transmit information between supply chain levels or even between individual plant divisions. It might be difficult for parties to ensure that the advantages of this cooperation are rewarded through the exchange of data. A helpful IT department that can offer the hardware and software needed for big data operations is also essential. Data analysts educated in huge volumes of data should be employed as well as experienced teachers to train Big Data analysts for the demands of the facility.

Advantages
Big data analytics may help organizations understand their business demands more effectively. In accordance with a demand boom, many firms design their company growth strategy, which might result in business growth in general. However, they should realize that a shift in market growth might leave them with a number of vacant warehouses and idle factories. Big data allows these companies to forecast the guidance of the market and create development plans based on this analysis.
Big data allows firms to construct a digital model of a complete manufacturing process. Data from consumers collected may be utilized to enhance marketing and sales operations. Splitting consumers into different groups, offering service to each group's demands and utilizing customer information to target where and when these new goods are being advertised is the other big data uses in marketing.
Big data analysis is not negligible to improve consumer loyalty. Most consumers would be loyal to the firm for the first time providing a high-quality service. Companies may utilize large-scale data analysis to forecast and meet consumer requirements to make them loyal customers.
Optimizing operations outside the usual limits of the firm, such as the selection of suppliers or technologies, requires a high level of information exchange across players in the supply chain.
Information sharing in supply chains has long been an impediment, but technical advancements in big data can simplify and speed up this process (Swaminathan, 2012).
Big data may be used from a logistical point of view for forecasting delivery times or optimizing delivery routing utilizing traffic, weather and drivers' information. A further use is to use product information for inventory management and sales choices (Waller & Fawcett, 2013).

Future research options
This thesis was prepared from an overview point of view to attempt to show the greatest contribution of data and data analysis to improving the performance of the supply chain. This technique did not make research too particular for some components of the principal supply chain operations. It is also one of the drawbacks to such a thesis; data analysis and data integration solutions specifically designed for each supply chain process are not discussed in detail, as that would lead to a very thorough, possibly very technical overview of certain solutions, and would not capture the overall use and value of such solutions. Future study might also incorporate empirical research in various business environments in order to better understand the requirements and challenges of using data analysis for a certain business field.
