A substantial body of literature discusses succession planning. The first book that addressed the topic fully was “Executive Continuity” by Walter Mahler. Mahler was responsible in the 1970s for helping to shape the General Electric succession process which became the gold standard of corporate practice. Mahler, who was heavily influenced by Peter Drucker, wrote three other books on the subject of succession, all of which are out of print. His colleagues, Steve Drotter and Greg Kesler, as well as others, expanded on Mahler’s work in their writings. “The Leadership Pipeline: How to Build the Leadership Powered Company”, by Charan, Drotter and Noel is noteworthy. A new edited collection of materials, edited by Marshall Goldsmith, describes many contemporary examples in large companies.
Most large corporations assign a process owner for talent and succession management. Resourcing of the work varies widely – from numbers of highly dedicated internal consultants to limited professional support embedded in the roles of human-resources generalists. Often these staff resources are separate from external staffing or recruiting functions. As of 2017 some companies seek to integrate internal and external staffing. Others are more inclined to integrate succession management with the performance management process in order simplify the work for line managers. -wikipedia
