Any living organism is born, lives, and dies. Business organization is a type of living organism, and it seems many major companies in Japan are getting to be ancient in age.
Maybe some companies can transform itself. But I believe best life for organization is just like in human’s life, that is, born, live, give life to another being, die. So it seems that the best way for company is give birth to companies (subsidiaries), let them go (for God’s sake, don’t send people who became redundant at the existing company!), and live out the remaining life fully, then die.
Perhaps our unwillingness to plan for death is reflected in the economy situation.
