10 years Vision

All employees can talk about "Own Dream" for their glorious future.

Yoshinori Miyachi

 The number of pages is about 70 pages although there are differences depending on the year. A management guidance document is like a compass showing the direction of the company if written easily.
You can understand in what direction the company is headed towards by looking at the guidelines.                                 
Every employee understands and shares that it is not intended to distribute it to all employees, regularly read back and retrospectively, and to create it.

I added a new 10-year vision in the guidance document. The 10-year vision is a concrete description of the company's future image.
Indicates the index every three years and clarifies the contents for achieving the goal. I think that the direction heading, the purpose has become clearer.

Have you ever thought about what will happen after 10 years from the company in which you work? 50 years after 20 years. Even if it is difficult for 50 years, I think whether it is better to do than I can not imagine the image after 10 years. By creating a guidance document again, various "dreams" are also spread by specifying the vision for 10 years again. From now on I would like to aim to create a company where all employees can talk a little more about "dreams" towards the future.
