The application of business process re-engineering in organizations co
ntinues unabated. A central issue that has not been sufficiently consi
dered is the method of identifying and choosing the processes which sh
ould be re-engineered. If the claimed benefits of substantial performa
nce improvement are to be secured, it is vital that a classification o
f process exists to facilitate selection of those most likely to deliv
er such benefits. This article considers the need for such a classific
ation and the responses currently available in the literature, and con
cludes that this Is both a critical and a neglected matter. A classifi
cation scheme explicitly linking processes to business strategy is pre
sented. The article concludes by illustrating how the scheme was emplo
yed by one organization during its re-engineering initiative to yield
significant benefit. (C) 1997 Elsevier Science Ltd.
