I took the course with a strong desire to build a data culture. I was able to draw a big picture of the processes through which data-based thinking and decision-making can be achieved, and through various examples, I was able to understand more clearly how the flow of thinking can be rational in detail. I think I was able to organize the information I had previously acquired fragmentarily from articles and other sources into a more structured way in my head. Above all, while listening to the course, I thought about how I could reflect this kind of thinking at my current workplace. Just by looking at the way the instructor organizes the course and answers questions, I can see how meticulously and systematically he thinks and works, so I think it would be good to trust him and take the course!
