This paper explores the relation between retail banks' branch-based process
es and financial performance. There are 11 processes included in this study
, which represent the bulk of the activities performed in a typical retail
branch (e.g., opening checking accounts). The first finding of this study i
s that the financial performance of banks that perform be tt er across thes
e processes tend to be better than that of other banks. in addition to the
variation in process performance across banks, there is also substantial va
riation across processes within banks. That is, banks that performed well i
n one process often performed quite badly in another. We present an analyti
cal model that shows that improvement in process variation can be more impo
rtant than improvement in aggregate process performance when dealing with c
ertain customer segments. Empirical evidence from the Wharton Financial Ins
titution Center Retail Banking Study of bank holding companies in the Unite
d States provides support.
