管理學大師彼得‧杜拉克（Peter Drucker）最受全世界管理界推崇的是他對社會、政治、經濟，甚至於個人對趨勢的洞悉與遠見、對經營管理的原理，都有深入淺出的看法，也因其對管理學的獨到創見，因而被譽為「現代管理學之父」。彼得杜拉克的成功，最了不起的地方是在於他對環境時時保持一顆警覺的心、對於新事物虛心學習的態度、樂於與人分享、堅毅的人格特質，以及其心目中習慣領域的理想境界。因此，本研究希望透過習慣領域的解析，以得知彼得杜拉克在造就他其偉大的成就的過程中，生歷階段中的七個光明信念、八個擴展習慣領域的方法，以及九個深智慧原理等邁向理想習慣領域的三大工具箱；希望藉由本研究分析與探討，進而啟發並開發我們自己的習慣領域，以達到理想習慣領域的境界。
