Lean Product Development Process with Design Verification Stages in the Value Stream of Automotive Industry
2021
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.
