Introduction

With a modern market that is characterized by high competition and volatility, organizations wish to pursue real cost control measures that will improve the bottom line and optimize profitability. Among the most eminent methods employed to that effect is leveraging Lean-a framework that focuses on the removal of losses, improving processes, and aligning functions for improved streamlining. Here, the production and management processes are continuously enhanced in a bid to reduce inefficiency and achieve optimum value to the consumer.

Meanwhile, effective use of Lean methods under modern conditions must be supported by the implementation of new digital technologies. Process digitalization, automation of business processes, and the use of modern information systems can significantly enhance the contribution of Lean methods to the minimization of the transaction cost. Particularly, technologies such as enterprise management systems, big data analytics and artificial intelligence (AI) help you to have a better comprehension of processes and allow you to make more well-informed management decisions in the moment. These types of technologies facilitate the possibility of greater productivity and quality control.

The purpose of the research is to explore the impact of Lean strategies and digital technologies on the reduction of businesses' cost of operation and their profitability. The article reviews the use of digital technologies in supporting and enhancing Lean techniques and advocates for the integration of these two areas for optimal cost and overall production process optimization.

Main part. Principles of Lean methodology and its impact on transaction costs

Lean methodology is a management system focused on minimizing losses and creating value for customers with maximum efficiency. The main ideas of this methodology are to continually improve processes, involve all the employees in the change process and strive to build a «lean» business. At the heart of Lean is the desire to eliminate wasteful resources that do not add value, such as excess inventory, long production cycles, and extraneous procedures [1]. The heart of Lean is to gain maximum productivity at minimum cost (fig. 1).

Figure 1. Lean principles

The first of the Lean principles is defining losses. The losses may be anything ranging from poor quality of the product to excess movement of material and people. The key loss categories are overproduction, waiting, inventory in excess, excess movement, defect, and idle production time. For example, Caterpillar is already implementing Lean methodology in its manufacturing operations by streamlining flows, removing waste, and increasing product quality. In 2024, the company reaffirmed its commitment to the Lean philosophy, declaring its commitment to excellence in safety and quality, and moving along the Lean Production way by aligning supply chains, reducing lead times, optimizing working capital, and improving availability [2].

The second very important principle is continuous improvement. It relies on the belief that improvements need to be continuous and systematic. While one-time fundamental changes do not apply, entails small but regular improvements. The changes can influence both technological operations and organizational aspects of work. Not only can product quality be enhanced through continuous improvement, but cost can also be minimized by maximizing work processes. This is important because every step towards improving quality or reducing costs ultimately reduces the operating costs of the company.

The third principle is to involve all employees in the optimization process. This principle is based on the understanding that improvements cannot be effective without the involvement of people directly working on the production lines. Engaging employees in the search for solutions and improvements helps identify hidden reserves and simplify processes, which in turn reduces costs.

These principles help not only reduce operational costs, but also increase the flexibility and adaptability of the enterprise, which is especially important in today's market conditions. Companies that use Lean methods can respond more effectively to changes in demand, improve quality, and innovate faster, which directly affects their profitability and sustainability in the market.

The role of digital solutions in Lean process optimization

Digitalization of business processes is extremely crucial to enhance the potential of Lean methods, both to speed up processes, but also to enhance their precision and effectiveness. Application of digital technologies into the system of Lean management helps to provide more in-depth examination of data, to make decision-making more effective and improve the efficiency of resource usage [3]. New communications and information technologies (ICT) such as process automation, enterprise management systems (ERP), and data analytics are increasingly becoming major strategies to minimize wastage and enhance productivity.

Among the most significant digital solutions is production manufacturing execution systems (MES), by which operations progress is tracked in real time and possible deviation from standards is detected. For example, General Electric uses MES systems to increase efficiency and quality in production. Proficy Smart Factory software facilitates real-time monitoring of production operations, deviation detection, and process optimization. This solution not only reduces cost, improves quality of the products, and reduces production cycles [4].

Apart from this, the use of big data analyzers can also improve decision-making processes in the Lean approach to a significant degree. Modern analytical software processes huge volumes of data, revealing hidden trends and possible problems that might have been missed in the traditional approach. For example, Amazon employs big data analytics extensively to optimize logistics and warehouse management. By using machine learning, Amazon facilitates the analysis of supply and demand data, allowing you to plan purchases more accurately and minimize product surpluses, thereby saving operational costs and optimizing the production process [5].

In addition, one of the most important components of Lean digital solutions is the Internet of Things (IoT), which allows you to get real-time data on the status of equipment and production processes. This information allows for immediate response to any deviation from the norm, preventing extended downtime and improving overall performance. Integration of IoT with the Lean system allows you to save big on repair and maintenance costs as you can take preventive actions before breakdowns occur.

Reduction of transaction costs with Lean and digital solutions

One of the main advantages of the introduction of the Lean strategy is a significant reduction in the cost of operation due to losses reduction, process optimization, and overall productivity improvement. In recent times, this strategy has been actively supplemented with digital solutions, thanks to which companies are able to achieve even more favorable results in terms of cost reduction. The fusion of Lean and digital technology not only makes resource management more efficient, but product quality also gets improved and faults reduced along the way throughout the whole process of production.

The first step towards the cost-cutting process is to use process analysis to diagnose and remove losses. Automating this step via monitoring and prediction systems greatly lessens the time spent to discover problems. As an example, predictive analytics platforms can analyze current data to predict future hardware malfunctions. This allows you to significantly reduce the cost of maintenance and maximize the utilization of resources. Therefore, digitalization not only prevents hidden losses, but also accurately plans resources and reduces repair and maintenance costs.

Another important aspect is the use of automation in the production process, which helps to reduce time costs and minimize errors. Automation of processes combined with Lean approaches allows you to speed up production, eliminate human errors and increase productivity. The introduction of robotic systems for automating assembly lines reduces labor costs and reduces production cycle time. This helps to significantly reduce transaction costs and increase product margins.

Digital technologies also play a key role in inventory management and logistics. The use of supply chain management (SCM) systems and integration with Lean methods allows you to reduce excess materials, optimize purchases, and reduce storage costs. For example, Walmart uses high-tech systems for inventory analysis and optimization, which allows maintaining a minimum inventory level, reducing logistics and storage costs [6].

Therefore, the integration of Lean practices with technology is an appropriate way of cutting operation expenses. The application of existing technologies like predictive analytics, automation processes, and inventory management systems can contribute to enhancing planning processes, decreasing losses, and increasing utilization of resources, thereby affecting the profitability and competitiveness of the firm.

Combining Lean methods and digital technologies to increase profitability

By applying Lean principles with assistance from digital technology, businesses are presented with new opportunities for boosting profitability that allow them to cut wastage, lower costs, and add value to their products. With the competitive and fast business environment, organizations are not only compelled to implement Lean practices but also complement them with advanced digital solutions in an effort to achieve flexibility, efficiency and accuracy of management. With this integration, there is a substantial improvement of operation efficiency and lowering of the cost of operation, leading to higher profitability (table 1).

Table 1.

The impact of digital technologies on key Lean principles

One of the well-known examples of successful implementation of digital platforms for production process optimization is Caterpillar, which has integrated Lean methods with IoT-based solutions, and also creates IoT-solutions actively. Following real-time data from sensors installed on the equipment, the company can instantly track production indicators, identify bottlenecks, and optimize processes according to timely and precise data [7].

The implementation of AI systems in the Lean management system assists in the improvement of the financial performance by automating analysis of large amounts of data and making planning, procurement and resource allocation processes more efficient [8]. AI is used for demand forecasting, supply chain optimization and inventory management. These solutions help reduce product overstocking, improve logistics, and improve the estimation of resource needs, improve production planning, and accelerate delivery processes, which in turn helps reduce operating costs and improve organizational efficiency.

The synergy of digital technologies and Lean also improves quality management, directly affecting defect cost minimization and efficiency. Digital technologies such as real-time data analysis and automated quality control systems help you quickly identify deviations and rule out deviations at an early point in time.

Thus, combining Lean methods with information technologies allows you to create more responsive, adaptive and lean production systems. Combining these two directions not only improves product quality and reduces costs, but also contributes to the growth of profitability of the enterprise, improving its competitiveness in the market.

Conclusion

The application of Lean methods and digital technologies significantly reduces operating costs and improves enterprises' profitability. Lean strategies based on loss reduction and process improvement are greatly enhanced by the use of digital solutions such as monitoring systems, predictive analytics, and automation. Instances of successful application of these practices in companies such as General Electric and Caterpillar show the excellent productivity of Lean and digital synergy in the real process of manufacturing. This synergy is not just productive in productivity and quality increase, but also reduces costs significantly, improving fiscal performance and facilitating sustainable business development in a competitive market.
