In this study we review over thirty years of succession research in an
effort to discern what we know conclusively about the subject, what w
e do not know because of mixed results, and what has not yet been stud
ied We begin by answering two key questions: (1) Why is succession suc
h an important topic? and (2) What makes CEO succession different from
other types of turnover? Next, we explore the three key stages of suc
cession research. The first phase covers the period from the 1950s to
the 1960s. This period is best described as the emergence of the field
. The second phase, covering the 1970s, reflects a period of theory bu
ilding and empirical investigation. The final phase from the 1980s to
the present is characterized by review and explosive growth. Following
our review, we use these combined studies to create an overall model
of succession-a model designed to offer prescriptions as to where rese
archers have been and where they should be going in the future.
