DX(Digital Transformation), DX,DX, so every time when I see the company website and discuss on the business, I have found this word, PoC, Agile, every words seems to be new. Actually, computing power and network speed are improving tremendously, so we can use amount of data very quickly. The world is changing. We have to do a paradigm shift. I have taken DX seminars in the company. The teacher mentioned that previous IT solution was to introduce excellent software with excellent SE, but what we need to do as current DX is to build IT literacy in the company to make IT culture normal. DX is not the purpose, but the tool to change the business process according to the new society. What do we need to do? It is not easy to build IT culture and skills in the company. Some experts understand IT solutions, others who are the current business experts do not understand IT mind. Discussion and sharing idea in each other has been more important. The word of efficiency has not been simple process like mathematics, but it is more like human-oriented thinking way to understand fresh and unknown field. I think facilitation is more important than before in the digital era. As a facilitator, I need to use DX materials and think about how efficient we can facilitate and create the value by using IT tools. The tool is also important, but as humans we need to think about facilitation for psychologically stable and deep discussions. There is no other way to communicate deeply with each other, no matter what environment has changed. Essential things depend on human.
