There are so many products or systems in the world that are hard to use. Jeffrey Rubin states five reasons for the continued existence of hard-to-use products or systems against all the efforts of usability specialists. Donald A. Norman says that each time a new technology comes along, new designers make the same horrible mistakes as their predecessors; technologists are not noted for learning from the errors of the past; they look forward, not behind, so they repeat the same problems over and over again.

Based on Rubin's and Norman's saying, I suggest that we should try to reduce the number of people who produce hard-to-use products or systems. To realize this, I proposed an idea of usability-minded people at the conference of HCI International 2005. Now, I'm trying to educate usability-minded people in our company to improve products and systems from their design stage by developers themselves.

These efforts are not done effectively by alone. To expel hard-to-use products or systems from the surface of the earth, we, usability specialists, should make combined efforts. Company people should consider the institutionalization of usability. Academic people should educate usability-minded young people who have flexible mind.

This is the most difficult task to do, but I believe that this is the most effective means to contribute to the ultimate ecology to utilize the limited resources on the earth.
