E-mail address: eva.bogner@faps.fau.de Abstract The fourth industrial revolution and the digital transformation are already major factors in the manufacturing industry and their importance is ever growing. However, the degree of their practical implementation has to be scrutinized. To define a status quo, it is important to analyze the situation and to identify deficits, starting points and unexploited potentials. Still, a detailed understanding of the fourth industrial revolution and the digital transformation is lacking especially in small and medium sized manufacturing companies. In addition, the fourth industrial revolution is associated by most companies only with logistics as well as production and manufacturing areas. The opportunities to integrate additional functional areas of the production process and the vertical value chain into the concept of the fourth industrial revolution are hardly considered. Starting from the point of view that the fourth industrial revolution is defined as a systematic increase in the flexibility of products and processes through automation, extensive networking and decentralized control mechanisms, as well as a data acquisition and integration through information and communication technologies, a study concept is developed. For this purpose, it is not enough to ask only for the present prevalence of technologies of the fourth industrial revolution. It is necessary to analyze the processes within manufacturing companies. A survey concept is developed that initially breaks down the vertical value chain as well as the production process into specific sub-processes. These sub-processes are analyzed regarding their degree of automation and digitalization and networking among themselves. The results of this survey presents concisely the call for action, the state of implementation and realized solutions of the fourth industrial revolution in Germany. Furthermore, impulses and best practices for innovative products and business models can be given. © Published by Elsevier B.V. This ©2016 2015The TheAuthors. Authors.

Introduction Prevailing factors in the manufacturing industry are the digital transformation and the fourth industrial revolution. As their importance is ever growing, their actual degree of implementation has to be captured. The definition of a status quo requires an analysis of the situation and an identification of deficits, starting points and unexploited potentials. However, there is a lack of a detailed understanding of the fourth industrial revolution and the digital transformation especially in small and medium sized manufacturing companies. The fourth industrial revolution may be defined as a systematic increase in the flexibility of products and processes through automation, extensive networking and decentralized control mechanisms, as well as a data acquisition and integration through information and communication technologies. Based on this definition a study concept is developed. The aim of this study is to provide insight to decision-makers of manufacturing companies about their current status with respect to the fourth industrial revolution and to derive recommendations for the integration of the value chain. Concurrently, a basis for decision-making should be given that explains how they can achieve an optimal cost-benefit ratio of their activities with respect to the fourth industrial revolution and the digital transformation. 2212-8271 © 2016 The Authors.

Study concept In the course of the study, a concept is developed that enables an objective determination of the degree of digitalization of different companies. 2.1. Subject of research The fourth industrial revolution is known as the introduction of the Internet of Things into the field of production [2]. New digital technologies like cloud computing, big data, cyber-physical systems and additive manufacturing accompany this informatization. The objective of the revolution is the production of individual products with the speed and costs of a comparable mass production. Consequently, there is a need for an increase both in efficiency as well as flexibility. But the implementation of information and communication technologies as well as the increasing networking within the production process alone will not bring about this industrial revolution. The fourth industrial revolution therefore is not limited to the production process. There must be a far-reaching change within manufacturing companies that goes beyond the production process. The technologies of the digital transformation enable completely new processes along the entire value chain, from research and development through manufacturing and sales to services concerning the use of a product [3]. At present, value chains from customer requirements through the product development to manufacturing are often grown historically and thus are inflexible. Digital potentials can be found at every stage along the value chain in different ways and degrees. In all, with an appropriate implementation the digitalization and the related information and communication technologies are able to make a decisive contribution to value creation. Thus, digitalization should not be considered isolated for individual areas and only as a supporting element of the corporate strategy. Rather, a holistic approach that covers all areas and functions of a company to exploit digital potentials and analyze each stage of its value chain separately has to be developed. This approach should be integrated into strategic planning and implementation. [4] For this reason, the study examines not only the degree of digitalization of the production process of different companies. Also all other relevant value activities and business processes are taken into consideration. Value activities can be divided into two general types, namely primary and supporting activities (see Fig. 1). Primary activities deal with the physical production of the product and its sale and delivery to the customer as well as the customer service. Supporting activities maintain the primary activities through the purchasing of inputs, the provision of technologies, the processing of queries and orders and cover various functions for the entire company. [1] Especially in the field of supporting activities, that are still strongly characterized by manual activities in contrast to the largely automated production processes, large efficiency potentials can be realized by their digitalization [5]. However, the concept of digitalization is often only associated with the "paperless office" in this field. Digitalization is significantly more than just the transfer from analog to digital data and documents [4]. Rather it is about the stronger networking between the business processes, the creation of efficient interfaces and the integrated data exchange and management. Table 1.

Value chain according to Porter 16 Eva Bogner et al. / Procedia CIRP 57 (2016) 14 – 19 The study is intended to examine the fields of the supporting as well as the primary activities. The selection of the fields of examination, however, is limited to those fields along Porter’s value chain with the highest expected needs for digitalization and digital potentials. This selection is listed in Table 1 in detail. 2.2. Research methodology In the further consideration the digitalization is seen as the integration and optimization of information and the flow of goods along the supply chain. The main basis for this is a consistently digitalized data flow without media discontinuities along the entire value chain of a company. To ensure this, all relevant fields of the value chain in a company need to be digitalized. The working hypothesis therefore is: The more consistently a company digitalizes its value chain, the less media disruptions are within the data flows. Thus, the degree of digitalization of the entire value chain of a company is the appropriate measure unit for its readiness for the digital transformation and the fourth industrial revolution. When operationalizing the measurement of the degree of digitalization, two issues have to be considered: x How can the status of a company based on its degree of digitalization be objectively measured and how can it be objectively compared with other companies? x How can a differentiation between aspects of the third and the fourth industrial revolution be achieved? During the last three industrial revolutions, activities and tasks which require only little or no specific qualification were automated through production facilities and robots. In course of the digital transformation, information and communication technologies and computer algorithms start to exploit new areas of the automation at high speed. This development can equally be said of an automation that it is achieved through the use of information technology because these technologies are able to automate processes where knowledge is systematically collected and processed as well as to analyze and to evaluate information. There is also a substitution of human labor as it can be found in the classical automation. However, a degree of automation can be achieved, that goes beyond the conventional automation. Through IT-based automation solutions, self-regulating processes can be realized especially in the field of the production process. [6] It is assumed that at the present many companies have difficulties to evaluate the individual level of digitalization of their processes and need support because of a missing methodology and missing standards. For this reason, the degree of automation should be used as a criterion instead of the digitalization degree. As explained above, especially in the area of supporting activities the automation degree allows to draw conclusions about the digitalization degree. Based on these considerations, two indices are created. The first index describes the level of digitalization across the entire value chain of a company. The second index determines the degree of automation of the production process isolated from the entire value chain. For this purpose, the production process is broken down into 21 generalized and transferable sub-processes which are analyzed in detail. The index formation for the two indices “Level of automation in production" and "Degree of automation along the value chain” is based on scoring models that contain the relevant question blocks that ask for the degree of digitalization in the defined fields of examination. The first set of questions queries the degree of automation of processes within the field of production. There are four answer options for each sub-process: x x x x 1 = mainly made by hand 2 = partially automated 3 = highly automated 4 = self-regulating In the fourth stage "self-regulating", it can be assumed that technologies of the fourth industrial revolution technologies have already been implemented successfully. The other levels are assigned to the technological level of the third industrial revolution at the most. The degree of automation of a company along the entire value chain is determined within the specified fields of examination (see Table 1). The answer options for these processes are: x 1 = mainly manually x 2 = partially automated x 3 = highly automated Based on the entire value chain "highly automated" is the highest possible degree of automation. Mainly concerning the field of supporting activities, this already implies a very high degree of automation and digitalization. Self-regulating processes are only to strive for in the production processes. Respondents could indicate that are not able to give any information about a process. Companies, which do not provide a certain process of the value chain, could also remark this. Furthermore, answering these two sets of questions is can be done from an objective point of view and independent of the state of knowledge and the current mind set to the fourth industrial revolution. The only prerequisite for answering the questions is the knowledge of the process landscape of the company. This is ensured through a filter at the beginning of the survey. 2.3. Effect examination In addition, the study analyses the effect of activities in the context of the digital transformation and the fourth industrial revolution. In order to develop a valid impact model, success factors in the form of measures and the associated target figures, which describe the resulting effects, have to be defined. Therefore, 23 methods and tools along the value chain have been selected, which are regarded as the substantial measures within the framework of the fourth industrial Eva Bogner et al. / Procedia CIRP 57 (2016) 14 – 19 revolution, for example predictive maintenance and the analysis of machine data in real-time. These represent the success factors that have to be evaluated. The operationalization of their actual implementation is realized by a three-point scale: x 1 = not planned yet x 2 = planned x 3 = already realized Simultaneously, these measures are assessed for their impact and their implementation success. This is done based on 14 target figures. A principal component analysis results in three impact dimensions into which they can be classified. These three overarching impact dimensions can be described as "productivity", "availability" and "customer satisfaction" (see Table 2. Target figures). To keep the evaluation of all criteria operable, a three-point scale with the following choices is used: x 1 = not yet realized x 2 = slightly positive change x 3 = very positive change Table 2. Target figures Impact dimension Target figure Productivity Increase in productivity Shorter set-up times Shorter delivery times Reduction of error rate Reduction of production costs Increase in quality Availability Reduction of on-site service visits Reduction of trouble-tickets Reduction of machine downtime Reduction of breakdowns Customer satisfaction Increase in customer satisfaction Reduction of complaint rate Reduction of hotline calls Increase in delivery reliability 3. Execution of the study For the purpose of the study, 211 manufacturing companies headquartered in Germany were interviewed. These companies come from different sectors: mechanical engineering, electrical engineering, medical engineering, logistics, information and communication technology. Only medium and large size companies are interviewed, small medium-sized companies are not considered. The operationalization is based on the Institute for Small Business Research in Bonn and thus slightly different from the definition of the European Union [7]. Companies with 150 up to 499 employees and a sales up to € 50 million are defined as medium-sized enterprises. Companies with 500 or more employees or a sales over of 50 million € are described as large enterprises. The selection of the companies is carried out randomly from a representative address list of 10,000 German companies. Thereby, large companies are quoted by a factor of 2.5 compared to medium-sized companies. Within the companies, directors or managers are interviewed. To meet the topics "degree of digitalization of business processes", functionaries, who declare, that they “hardly know” the detailed business processes are excluded from the survey. The study was carried out both by means of interviews and an online questionnaire. The content of the questionnaire was identical for both methods. 4. Results The study results show that the basic preconditions for the fourth industrial revolution and the digital transformation have not been given yet. One the one hand, this is due to the high degree of manual processes along the entire value chain. The field of production has the highest degree of automation within the value chain. About 90 percent of the examined companies have production processes that are partly or even highly automated. The areas of marketing, after sales and product development show the lowest degree of automation. On the other hand, the examination of the degree of automation along the production process shows that less than 20 percent of the companies provide the conditions for an integrated engineering and the fourth industrial revolution. However, only the companies which fulfill these prerequisites are fulfilled, provide consistently automated and selfregulating processes. All other companies still have a very high percentage of manual processes and thus a barrier-free data continuity along the production process is not possible. The results of both analyses are shown in a scatterplot diagram. Each point in this diagram represents a company examined in the study (see Fig.2). Each company is described by the maturity level of digitalization (x-value) of its entire value chain and the degree of automation of its production (yvalue). It can be seen that there is an approximately uniform distribution of companies around the zero point. On the one hand, there are companies that have a relatively high degree of automation in production. However, they just put little focus on the automation of the entire value chain. These often are companies which persist in the era of the third industrial revolution. On the other hand, there are companies where it is the other way round. There are also a number of companies within the manufacturing industry, whose maturity level is below average both in the automation of the production as well as the entire value chain. The companies in the upper right quadrant of the scatterplot diagram have already taken a major step forward in the comprehensive automation. They show a high level of maturity in both fields. 17 18 Eva Bogner et al. / Procedia CIRP 57 (2016) 14 – 19 Fig. 2. Results of the study The next step is to answer the question to what extent the fourth industrial revolution and the digital transformation contribute to the success of a company. In order to answer this question the characteristic of the target figures, that describe the effect of the digitalization, is analyzed. This measurement is independent from the degree automation. Looking at the average values of the companies in the 4 quadrants of the scatterplot, shows a significant relation between the division within the scatterplot diagram and the success factors of a company. Based upon this, the following classification is made: x Cluster 1: Good practices (Companies in the upper right quadrant of the scatterplot) In companies that have high degree of automation in both dimensions, the implementation of the success factors of the fourth industrial revolution is clearly above average. These companies generate the largest contribution to the corporate success through their measures. x Cluster 2: Marketeers (Companies in the lower right quadrant of the scatterplot) These are companies that just pushed the automation of the entire value chain and have rather neglected a further automation of their production. Accordingly, the success factors related to the integration of the different stages of the value chain are at an above-average level. The production process is still rather on the state of the third industrial revolution, since the production-related success factors are less taken into account. Interestingly, the determined contribution to the corporate success is lower in these companies. x Cluster 3: Keeper (Companies in the lower left quadrant of the scatterplot) Companies in this cluster are very cautious about the automation of their processes. They rather remain in their existing structures and processes than implementing new technologies. If any, these keepers achieve increases in productivity that are below average and a slight increase in customer satisfaction. x Cluster 4: Technologists (Companies in the upper left quadrant of the scatterplot) Manufacturing companies of this cluster, focus on the automation of production. They perfectly implemented the technologies of the third industrial revolution. However, they are just at an average level with respect to the automation of the entire value chain and the implementation of self-regulating production processes. This is also reflected in the resulting average contribution to corporate success. This positive correlation between the high degree of automation of both the production and the entire value chain and the resulting contribution to the corporate success becomes even more apparent by the aggregated values of the indices in Table 2. However, the question arises, if the size and type of the production of a company have an impact on the results. The analysis of separate scattering diagrams for large enterprises and medium-sized businesses, as well as companies with a mass production and companies that produce in batch size 1, shows that all scatterplots have an approximate equal distribution. Thus, the company size and the design of the production system do not affect the division into the different company types. Eva Bogner et al. / Procedia CIRP 57 (2016) 14 – 19 Fig. 3. Comparison of the company types 5. Conclusion Acknowledgements It is obvious that the automation and digitalization of the entire value chain as well as the simultaneous consideration of the success factors of the fourth industrial revolution increase the company's success significantly. The more both are implemented in a company, the higher its performance. This performance is also a good indicator of the capacity of a company with respect to the fourth industrial revolution and the future success of the company. In addition, the study shows that the fourth industrial revolution holds great potential benefits. It is necessary to focus on changes in the production process. However, many potentials can only be exploited if the processes along the entire value chain are involved in these changes. Only the automation and digitalization across the entire value chain of a company leads to a greater contribution to corporate success. Many companies have not yet recognized these opportunities. From today’s point of view, only one quarter of the surveyed companies of the manufacturing industry will be able to cope with the disruptive changes of the fourth industrial revolution.
