From 1957 to 1990, Donald ·E·Super, a famous master of career planning, broadened and revised his lifelong career development theory. During this period, his main contribution was "Rainbow Map of Career".

During the period from 1976 to 1979, Schuber conducted a four-year cross-cultural study in Britain, and put forward a broader new concept-the career development view of life breadth and living space. Schuber joined the role theory and described the interaction between career development stages and roles, thus comprehensively describing the career development prospect of multiple roles.

Schuber named this career development map of life span and living space "Life Rainbow Map", which vividly showed the time-space relationship of career development and better explained the definition of career.

A rainbow spanning a lifetime-the width of life

In the rainbow picture of a lifetime, the level represents the width of life that spans a lifetime. The outer layer of the rainbow shows the main development stages of life and roughly estimated age: growth period (about equivalent to childhood), exploration period (about equivalent to adolescence), establishment period (about equivalent to pre-adulthood), maintenance period (about equivalent to middle age) and decline period (about equivalent to old age).

In these five main stages of life development, there are still small stages in each stage. Schubert did not emphasize that the age division of each period has considerable flexibility. It should be decided according to the different situations of individuals.
