| Abstract: | This paper presents a new approach to measuring the input productivity
gains from information technology (IT) in complex managerial
environments. The approach is illustrated in the context of a study of a
pilot deployment at Hardee's Inc. of a new cash register point-of-safe
and order-coordination technology called âPositran." The
method employs data envelopment analysis (DEA) and nonparametric
production frontier hypothesis testing to determine whether the
performance of restaurants that have deployed Positran is better, on
average, than for those that have not. The design of the study is of
special interest because it approximates a controlled experiment. Our
results show that Positran helped to reduce input materials costs, since
restaurants that deployed the technology were less likely to be
inefficient It is further possible to characterize the class of
restaurants for which the relationship holds. Operational efficiency
measures such as the ones we have developed provide managers with the
opportunity to implement deployment strategies for new ITs in order to
maximize value. |
