Furthermore, section 2.3 covers the manufacturing impacts of e-procurement in various industries, and section 2.4 covers the role of e-procurement in operational efficiency and productivity.

E-Procurement

E-Procurement, commonly referred as electronic procurement, is the procedure for ordering products and services using technologically advanced platforms and systems. Through the use of digital technology, e-Procurement has turned out as a transformational force that is changingtraditional procurement practicesthrough the use of digital technology.It covers the entire procurement lifecycle, from order to payment,electronically which encourages efficiency, transparency, and collaboration (Chaffey et al., 2019). E-Procurement streamlines all the processes in procurement from sourcing, supplier management, and contract negotiations, to payment methods (Gunasekaran & Ngai, 2012).

Technology developments have resulted in the creation and evolution of specialized e-procurement platforms and applications. Procurement has evolved from paper-based methods to digital methods. Manual paperwork is removed, processing times are shortened, and overall efficiency is increased due to digitalization(D Neef, n.d.). The evolution towards E-Procurement gained momentum as organizations sought ways to leverage technology for enhanced efficiency and cost savings.The emergence of E-Procurement accelerated as organizations started looking for methods to increase efficiency and eventually cost savings.

E-Procurement provides set of methods, each provided to specific stages of the procurement lifecycle. E-Sourcing involves gathering and evaluating data about a number of suppliers in order to identify the potential one(Ellram& Carr, 2005). With E-tendering, requests are sent for information and prices to suppliers, facilitating them to submit their proposals and making it simpler for the buyer to analyze the necessary data and make a better, more informed conclusion(Matunga, D. A., Nyanamba, S. O., &Okibo, W.,2013). In an electronic auction, commonly referred to as a reverse auction,vendors compete with one another online for contracts based on disclosed specifications (M Islam, T Zhu,2012).E-invoicing digitizes the payment processes and involves the exchange of invoice documents electronically between a supplier and a buyer resulting in shorter payment cycles and fewer mistakes (Xu et al., 2015). Together, these techniques improve procurement effectiveness, lower human error, and increase in transparencyof procurement activities.

Previously, in order to manage data in procurement, businesses had to download and install a number of applications on a physical server but now with the integration of cloud computing, organizations access e-Procurement systems with endless capacity, facilitating scalability (Prajogo&Olhager, 2012). E-procurement systems have unlimited capacity to easily deal with all of these tasks and keep up with the growth.The capacity to use a digital strategy to purchase goods and services from around the globe has increased process optimization and market competition(Cheong, T. Y., Sulaiman, A., & Parveen, F., 2009). Technology advancements have transformed the approach to business operations. Itincorporates work automation, encourages cultural transformations, and eliminates any barriers between stakeholders and departments. (Swan et al., 2019).

The evolution of procurement practices from manual methods to E-Procurement reflects how firms have changed their processes of business operations in the digital age. Due to technological advancements, e-procurement methods enable organizations to source, negotiate, order, and pay electronically leading to efficient procurement processes.

Additionally, these systems assist workers in adhering to best practices in procurement. In the context of Germany's complex and diverse landscape, the use of electronic tools for process automation and standardization has encountered growing challenges. This situation is regrettable, considering the extensive distribution of procurement professionals among 30,000 contracting bodies in Germany. The process of diffusion enhances the significance of knowledge transfer and standardization, since these activities have the potential to enhance the capacities of procurement employees at the state and local levels.

However, the introduction of competition in the e-procurement market yielded numerous advantages. For instance, it empowered contracting authorities to exercise their discretion in selecting the most suitable platform for their specific procurement requirements. The introduction of competition in the e-procurement sector enables e-procurement providers to offer novel solutions to public purchasers. This implies that public purchasers are not obligated to select from a market that is monopolized and controlled by a single provider. Consequently, this phenomenon results in a flourishing market.

There exists a direct correlation between the expeditious and effective processing of an order and its associated cost, hence highlighting the paramount importance placed on both swiftness and precision. For instance, in the context of e-Procurement, it is possible to obtain quotations and approvals prior to initiating the creation of a purchase order. This efficiency benefits enterprises by saving time. The utilization of e-Procurement streamlines the negotiation process by facilitating interactions with suppliers and business partners, regardless of their geographical location. In the realm of business, the value of time is often equated to monetary resources, leading to a concerted endeavor to minimize unproductive worker hours. In the present day, e-Procurement has expanded its reach beyond huge enterprises equipped with extensive procurement departments. Various tools and technologies, such as online auctions, web-based procurement systems, and purchasing platforms, enhance the procurement process by providing a more interactive and hands-on approach.

The e-procurement system facilitates the measurement and monitoring of orders, including many parameters such processing time, order submission time, and current status. As a component of the adoption, procedures are standardized and enhanced, while activities that do not contribute value are eliminated. The implementation of process automation leads to the elimination of paper documents, hence facilitating expedited order approval and document processing. Both the sales department and the purchasing department possess identical access to the data. Prior to the implementation of the system, the purchasing staff is required to respond to inquiries from sales personnel, resulting in a significant expenditure of time. Through the utilization of e-procurement, sales personnel are empowered to access and review any pertinent information on their computer systems, so enabling them to promptly address any inquiries that may arise. The process of digitalization has been found to enhance the efficiency and effectiveness of both procurers and enterprises, leading to increased productivity. There is potential for Germany to enhance its utilization of electronic procurement methods. The expansion of privately owned e-procurement technologies in the market-driven approach has resulted in a progressively intricate business environment. The systematic collection and analysis of data using advanced technologies is of utmost importance in monitoring procurement performance across the system.

The effectiveness of an e-Procurement system in the workplace is contingent upon its adoption and consistent utilization by employees, similar to the introduction of any novel technology. The utilization of e-Procurement systems is occasionally met with resistance from end users due to its self-service nature. According to reports, there is a reported compliance rate of just 65% among employees when it comes to purchasing contractual things. This lack of compliance has resulted in organizations missing out on potential cost reductions of up to 22% that could have been achieved through adherence to contract terms. Maintenance operations necessitate a more extensive range of suppliers compared to other company tasks. Consequently, an electronic procurement system must facilitate access to a diverse and comprehensive supplier base. A significant number of suppliers, particularly those who are smaller in scale, lack the technological capacity required for seamless integration with e-Procurement platforms. Some organizations may face limitations in terms of their IT infrastructure and financial resources, which could hinder their ability to implement e-Procurement systems. Additionally, there may be concerns among these organizations that e-Procurement could potentially empower buyers to negotiate lower prices.

The most crucial determinant of success in the implementation of e-procurement among large-scale manufacturing enterprises in Germany is the level of dedication exhibited by both employees and management. In order to achieve success, an eProcurement system should enable employees to concentrate on their primary responsibilities while also addressing the requirements for visibility and management necessary to properly oversee organizational expenditures. This objective can be accomplished by providing comprehensive staff training and effectively disseminating the relevant guidelines and procedures that facilitate the seamless utilization of the technology. The responsibility of establishing the vision and goals that align with the objectives of the firm lies with the management. It is imperative to develop policies and establish strategic frameworks that facilitate the integration of the technology. The management should equally ensure the provision of adequate financial assistance required for the development of e-procurement infrastructure, facilitating its seamless adoption.

The reliability of information technology plays a critical role in the successful implementation of e-procurement. The implementation of dependable electronic systems contributes to the reinforcement of information security, so reducing potential dangers and ultimately fostering greater levels of acceptance among both providers and purchasers. To attain trustworthiness, it is imperative for German-based large-scale manufacturing enterprises to maintain the completeness, relevance, and comprehensibility of their website contents, while also prioritizing security measures. This will allow providers to carry out their transactions with lowest levels of risk. The supplier's performance is a crucial factor in determining the success of e-procurement adoption among large-scale industrial enterprises in German. Consequently, it is imperative to involve suppliers in the initial phases of e-procurement implementation. Providing training to suppliers regarding the utilization of technology would have a positive impact on the adoption of e-procurement, hence improving overall performance. In order to ensure comprehensive decision-making, it is imperative for the management to include suppliers in conversations pertaining to system modifications. The successful implementation of e-technology in large-scale industrial enterprises in Germany can be facilitated by this.

What challenges and barriersare encountered during the implementation of e-procurement, and how to mitigate these challenges?

It is generally agreed upon that the users' buy-in to e-procurement platforms is one of the most important factors in the effective implementation of the practice. The passion of users for electronic procurement systems is essential to the successful adoption of these systems because it creates an atmosphere conducive to learning in which individuals are driven to acquire the skills necessary to make efficient use of the technology. As a result, this makes it significantly simpler to incorporate a wide variety of operational procedures into the system. If senior management recognizes the value of user comfort and chooses to implement a user-friendly application, then the degree to which the electronic procurement system is user-friendly will be proportional to the degree to which this understanding is present. Users are able to view electroniccatalogs, purchase orders can be automatically routed to the proper management for approval, orders can be forwarded to suppliers, expense reports can be generated, and the system is designed to be simple to use by its end users. This movement has the potential to enhance the widespread adoption of electronic procurement systems among the top manufacturing businesses in Germany.

User-Friendly Technology:

The analysis of participants' opinions on the usability of e-procurement systems reveals a positive attitude. A significant 40% of respondents felt that e-procurement systems are easy to understand and use, with another 19% strongly supporting this idea. A minority of 14%, on the other hand, disagreed. This understanding of user-friendliness perceptions influences how easily e-procurement solutions are adopted in the firm.

Transition Ease:

The study also reflects respondents' perceptions of the ease of switching from traditional to electronic procurement processes. A majority of 39% strongly agreed that the changeover is straightforward, and another 36% also agreed. This indicates that most of the participants think the change is achievable.

Positive impacts of E-Procurement:

As these findings aim to highlight the complexity of e-procurement's impact on organizational performance, the results show that the majority of the respondents agree that E-procurement has the potential to bring about significant improvements in an organization's overall performance and operational efficiency. The impact of e-procurement on performance, productivity, and efficiency in Siemens is a pivotal focus of the study. These survey results highlight the respondent's wide variety of opinions about how e-procurement affects performance, operational efficiency, and productivity.This agrees with the view shared by Eva Kenková et al. (2021), that the Digitalisation transitioning procurement has led to further growth of Siemens through the increase in efficiency. In addition, these findings indicate the claimed benefits of e-procurement in compliance management and cost-cutting initiatives. Although many respondents acknowledged the advantages, a small percentage mentioned challenges or had mixed feelings. These findings highlight the complexity of e-procurement's impact on organizational performance.

Challenges:

The findings also make clear the difficulties in adopting e-procurement. The necessity for technical preparedness is shown by the fact majority of the respondents cites advanced technology as a serious challenge. In addition, the high cost of the software and other associated costs also affect the implementation. Furthermore, lack of knowledge and technical skills to use e-procurement tools stand out as major roadblocks. These observations highlight how crucial it is to address implementation issues and training techniques while developing an e-procurement system.

6. Conclusion And Recommendations

Conclusion

The results demonstrate an encouraging trend in the adoption of e-procurement methods, with a substantial proportion of participants actively using e-procurement practices. The survey's findings provided important new information about user-friendly technology, transition ease, beneficial effects, and difficulties in implementing e-procurement.

The first objective of the study was to examineto what degree has e-procurement been incorporated into Siemens' procurement processes. The findings show a considerable adoption rate, with the majority affirming extensive and showing constant use. These numbers demonstrate Siemens' dedication to incorporating digital solutions, which is especially apparent among participants between the ages of 31 and 35 andthe majority of them were familiar with the basics of e-procurement and comfortable with its workings.The fact that e-procurement solutions are user-friendly and promote easy integration into workflow was noted by a significant number of respondents. The majority of participants also believe that switching from conventional to electronic procurement techniques is feasible, which emphasizes the organization's preparedness for digital transformation.

This study utilised survey analysis techniques to construct a metric for assessing the extent of digital transformation within industrial firms. An empirical examination was conducted to assess the correlation between digital transformation, ambidextrous innovation, and company value, taking into account the aforementioned variables. The results suggest that the implementation of digital transformation in industrial enterprises has a substantial impact on their overall enterprise value. Digital transformation has the potential to enhance enterprise value by using technological innovation, business model innovation, and the synergistic integration of these two elements. The impact of digital transformation on the enterprise value of manufacturing enterprises is characterised by a singular threshold effect resulting from technology innovation, whereas a dual-threshold effect is observed in relation to new business models.

Secondly, the study aimed to investigate the impacts of e-procurement adoption within industrial processes.The results show a promising trend, showing that e-procurement considerably boosts productivity, operational efficiency, and performance.The majority of respondents acknowledged that the use of e-procurement had the potential to significantly increase overall performance, operational efficiency, and productivity in addition to providing benefits for compliance. The study also highlights the complexity of impact, emphasizing both good and detrimental effects of e-procurement.

The final aim to look at, though, is the implementation phase, where there are issues. Implementation issues and a lack of knowledge and technical skills that will help in dealing with advanced technology stress the need for extensive change management strategies that address these obstacles head-on. Technical specialists are required for the training of staff members that can enable more effective integration of e-procurement technologies into processes and deal with cutting-edge technology.

Limitations

The current research mainly focused on identifying the degree of usage and impacts including benefits and challenges of implementation of e-procurement practices in Siemens, which might limit the generalizability of the findings to other industries or organizations with different structures, cultures, and contexts.
