    Lean product development process with design verification stages in the value stream of automotive industry
    (Scientific Research Publishing, 2021) Paker, Fuat Ali
    In the automotive industry, lean projects and innovation creation come to life by being updated under the control of systematic interdisciplinary process flows. The lean product development process that changes the shell, defined under the light of the variables created by the competitive conditions, is today measured by the value flow efficiency and the global market spread of the final product. Consequently, the lean product development approach, which aims to identify and purify all the wastes that do none value or create value to the system or cause burdens in the new product development process, is shaped by step-by-step approvals in the flow. In the main automotive industry company practices within the scope of the research (3 national, 3 international), the beginning of the concept of lean in design is to define and optimize the steps in the product development process under the value stream map. Therefore, the product function for which the customer has paid for, the function of the new product or the physical structure used to meet the needs in question, the comfort, life, experience, innovations of the scope that constitute the new product concept are planned and verified and implemented in the simplified automotive design stages at the beginning of the lean product development process. In this research, initial automotive design objectives and stages are at the focal point of the innovation and added value creation brought by the concept of “lean” approach. The research is modelled on the determination of steps that do not create added value together with the points where the flow circuits’ or stems, the process is devalued, the interdisciplinary holistic studies intensify, the information and delay begin and end in the sequential and simultaneous design validation step transition stages, which are examined under the lean approach. As a visual and virtual tool that enables the elaboration of nominal values such as the total duration of the design verification stages and the influence of interdisciplinary stakeholders or the test level of the product design with the new product added, it reveals the value flow or losses. Hence research; from innovation creation and new product design steps, which constitute the initial stages of the lean product development process, to design verification analysis, the efficiency of the automotive company processes within the scope of the research has been measured by comparing using lean automotive design techniques, methods and concepts.

    The republic period of the Turkish automotive industry and product design
    (Scientific Research Publishing, 2021) Paker, Fuat Ali
    After the First World War, during the transitional period the Republic of Turkey from the Ottoman Empire, this qualitative research that sheds light on changes and variations were the focus of the industry, for the conservation and use of located original value in the historical development, it has been compiled with archival-tracer information. The Ottoman Empire, after the industrial revolution, these historical studies that discussed the effects of the touch industry has ceded to the Republic of Turkey, in the automotive assembly industry realized the product development and product design activities, with examples of significant diffraction in all, were transferred with qualitative data. The main objectives of the study are how and why the automotive industry, which was established before the world wars and restructured afterwards, came to life in the global context and the regional developments it showed. Therefore, in the coming days, the study was carried out in a narrow field in order to understand the global integrity where geographical regions converge, and the structure in which full integration has been completed in companies and organizations in the automotive industry. In this context, the geographical continent transition taking place among Turkey’s automotive industry, within the limits of qualitative studies, creating a historical perspective, the region, released today stems from the importance of global integration centers. In this context, Turkey is located between geographic continent transitions to create operating limits of the automotive industry, the global integration of the indicator is due primarily to the fact that the reveal. The study evaluated two different development structures in the automotive industry: mass manufacturing and vehicle design, product development. Therefore, examining the development of the automotive assembly industry in the light of original product design studies, which constitute the basic requirement of mass manufacturing, strengthened the cause and effect flow. Under the new technology-oriented, original product design, the enhancement or sustainability of global competitiveness, regional mass manufacturing industry, specific applications for the automotive sector were included in the findings and main results of the research. In addition, the use of common platforms and parts between global companies in the automotive assembly industry or a common design approach in cost-oriented mass manufacturing has been determined within the scope of the research boundaries. The global competition that shapes the basic development of the automotive industry, the brand and model memory of regional markets, short product life cycles, product diversity and increasing consumer demands, predictable implementation of similar basic strategies have shaped the background of the study. Research limits built-in, well situated Turkey’s automotive assembly industry in the 1960s to set up and under liberal policies in the mid-1980s to be included with mass manufacturing capacity with a special agreement with the European customs union, today, global integration, to be completed by Asian companies cannot stay away from the expected in this sector in the working axis is revealed.

    The “static” and “dynamic” design verification stages of the lean development process: Automotive industry
    (Scientific Research Publishing, 2020) Paker, Fuat Ali
    The design verification steps that take place in today’s automotive industry, which constitute the values of each successive or simultaneous phase in the new product development process, create a complex structure with the inclusion of each new technology and discipline. Therefore, step by step, each design verification phase definition in the flow contains important phase transition measurements or approval tolerances that ensure the simplicity and continuity of vehicle development processes. In addition, classification of design verification stages within the framework of this study or evaluation in two classes (static and dynamic) is a new approach, but it is a synthesis with the analysis of the new product development process. The vehicle’s basic structure, which constitutes the ergonomic and functional requirements of the vehicle in a static environment, takes into account the dynamic environment variables with crash or accident tests. Increasing new technology adaptations in the automotive industry have changed the new product development process that performs this function structurally and created the concept of design verification under consecutive or simultaneous process simplicity. From the autonomous driving to the use of alternative energy, possible accident scenarios and design verification phase transitions in the integration of parts and systems of the newly developed vehicle create a new structure that models and directs the lean product development process especially in the automotive industry in the coming days. In the lean product development process that takes place in the automotive industry, the design verification transition steps or the approval-control analysis of the development stages, which form a new and effective approach, are re-modeling the entire flow. Therefore, successful execution of design verification steps used in the control of new interdisciplinary product development phase transitions provides value creation. Within the scope of this study, the effectiveness of the static and dynamic design verification steps, which are carried out in 5 global automotive companies included in the research, which constitute the stage transitions of the new product development process, has been measured. Apart from the design verification transition stages, the process variables that differ among the automotive companies involved in the research are excluded from the scope of this study. In other words, in field researches in the automotive industry, new vehicle design steps or basic engineering steps in the new product development process steps, while creating independent fixed variables, interdisciplinary collaborations, static and dynamic design verification transition stages they perform, or their sequence in the basic flow, is accepted as a dependent variable. Therefore, in the study, the positive effect of the automotive companies that included the static and dynamic design verification phase transition approvals in the lean product development process was investigated. Under the comparative analysis structure of the research, the effect of automotive companies, which accept international vehicle specifications as static design verification input, on market performance has been examined in depth. The detailed depth in the comparison analysis conducted under the second field studies of the study is due to the prediction of dynamic design verification stages to provide a high impact on the market performance, according to the static verification analysis. The new product development stages of the dependent variables were fixed and the flow-oriented “effect” of the independent variables in the basic process influenced by the design verification activities was analyzed under the new automotive industry company comparisons. In addition, the impact of the automotive design activities that make up the comparison analysis of the research on the scope of the lean product development stage and its effect on the basic process flow has been demonstrated competition-oriented. Therefore, sub-variables, options, criteria, results, which form a defined comparison problem, create basic test values that affect the problem.
