This book lays the theoretical foundation for a comprehensive individual and organizational consideration of Ikigai by describing Ikigai as a Japanese philosophy of life and, on the basis of original logotherapy of Viktor E. Frankl, opening up Ikigai for the non-Japanese cultural area. The necessity of a purpose driven view is explained and individual Ikigai is transferred to the organizational context as a blueprint. The four central levers of organizational Ikigai are described and the theoretical foundations for a transformation to a purpose-driven organization are presented.
