Abstract: In the automotive industry, lean projects and innovation creation come to life by beingupdated under the control of systematic interdisciplinary process flows. Thelean product development process that changes the shell, defined under thelight of the variables created by the competitive conditions, is today measuredby the value flow efficiency and the global market spread of the final product.Consequently, the lean product development approach, which aims to identify andpurify all the wastes that do none value or create value to the system or causeburdens in the new product development process, is shaped by step-by-stepapprovals in the flow. In the main automotive industry company practices withinthe scope of the research (3 national, 3 international), the beginning of theconcept of lean in design is to define and optimize the steps in the productdevelopment process under the value stream map. Therefore, the product functionfor which the customer has paid for, the function of the new product or thephysical structure used to meet the needs in question, the comfort, life,experience, innovations of the scope that constitute the new product conceptare planned and verified and implemented in the simplified automotive designstages at the beginning of the lean product development process. In thisresearch, initial automotive design objectives and stages are at the focalpoint of the innovation and added value creation brought by the concept of “lean” approach. The research is modelled on thedetermination of steps that do not create added value together with the pointswhere the flow circuits’ or stems, the process is devalued, theinterdisciplinary holistic studies intensify, the information and delay beginand end in the sequential and simultaneous design validation step transitionstages, which are examined under the lean approach. As a visual and virtualtool that enables the elaboration of nominal values such as the total durationof the design verification stages and the influence of interdisciplinarystakeholders or the test level of the product design with the new productadded, it reveals the value flow or losses. Hence research; from innovationcreation and new product design steps, which constitute the initial stages ofthe lean product development process, to design verification analysis, theefficiency of the automotive company processes within the scope of the researchhas been measured by comparing using lean automotive design techniques, methodsand concepts.
