The relative importance of strategy and structure lies at the heart of the
strategic management field, yet little is known about the associated perfor
mance implications of such changes. The purpose of this study was to invest
igate the financial performance impact of strategy and structure changes. W
e conducted an examination of 259 firms over a 36-year period using a quasi
-experimental design. No significant change-performance relationships were
found for tandem changes (i.e. when both strategy and structure were change
d). But, we found that singular structure changes were associated with the
highest performance. This finding was consistent with the theory: though st
rategy is important, proper deployment of firm uniqueness is paramount to p
erformance enhancement.
