Recent trends in organizations and the findings of the entrepreneurshi
p literature suggest that middle managers, including MS/OR practitione
rs, need to function as internal corporate entrepreneurs. To survive a
nd to succeed in changing organizations, middle managers need to think
and to act as intrapreneurs. I hypothesize that as the structure of o
rganizations becomes more amorphous, middle managers who exhibit intra
preneurial behavior perform more successfully than those who exhibit t
raditional behavior. Implications for middle managers and MS/OR practi
cioners are (1) to be more creative and innovative; (2) to constantly
improve and extend their range of skills, and (3) to link their effort
to the strategic objectives of customers.
