Different succession processes can be placed on a continuum ranging from relatively simplistic and bounded to relatively complex and comprehensive.[13]
At the most simplistic end of the continuum, replacement planning denotes a minimal succession approach in which successors (i.e., replacements) are identified at the top two or three managerial levels, but there is little or no development of those successors other than ad-hoc on-the-job experience. The focus is on forecasting, with no attention to development issues. Succession planning falls near the middle of this continuum of succession processes. It is more systematic and extensive than replacement planning because it is linked with intentional development initiatives targeted at successors; however, it is mainly for the top two or three management levels, like replacement planning. Succession management anchors the most comprehensive end of this continuum in that it identifies successors (replacement planning), develops them (succession planning) and is also directed at all managerial levels. The overarching goal of succession management is to have a pool or pipeline of prepared leaders—and not just a list of prospective candidates—across all organizational levels to fill vacancies in key positions when needed.
