Level: Beginner
Although no engineer doubts the effectiveness of experimental design, not everyone in the Japanese industrial field practices it. One reason for this is that our predecessors translated the word "design" in "Design of Experiments" as "plan," which emphasized only the technical aspects of experimental design and led to it being understood as a magical method.
Design is not just about deciding the appearance of a car or clothes; its essence lies in problem solving. In recent years, design thinking has become more widely known, and with it, for example, more and more people are beginning to understand the difference between career planning and career design. If this is the case, now is the time to rethink experimental design as a way of solving problems.
If the purpose of experimental design is to solve problems through experiments, it does not mean that only a few engineers involved in product development should carry it out. The power of experimental design is realized only when all the parties involved with the problem participate.
However, those upstream and downstream of the development department, such as the planning department and those closest to users, may be unsure of where to start as they lack the familiarity and experience. Therefore, in this presentation, I would like to provide some hints for experiment planning using demonstration examples.
