The purpose of this paper is to develop a set of measures of purchasing's c
ompetitive priorities. We maintain that purchasing is a strategic contribut
or to the firm, and that the selection and retention of external suppliers
is a fundamental and strategic purchasing task that manifests the function'
s competitive priorities. Researchers and managers increasingly view the op
erations and purchasing functions as intimately linked, and as playing impo
rtant roles in supply chain management. Ultimately, the performance of the
operations management system, measured in terms of quality, cost, delivery
and flexibility, depends on inputs secured by the purchasing function from
the firm's suppliers. However, in a search for substantive relationships, t
he purchasing Literature has largely overlooked methodological issues such
as measurement. Using empirical data collected from North American purchasi
ng executives, a confirmatory factor analysis provides evidence that purcha
sing's competitive priorities may be conceptualized similarly to the compet
itive priorities in operations, with key differences. The measures satisfy
key measurement criteria including unidimensionality, convergent validity,
discriminant validity, and reliability. Five competitive priorities form th
e basis of a multidimensional measure of purchasing's competitive prioritie
s, the individual factors of which will allow for the examination of linkag
es between purchasing, operations and other parts of the supply chain. (C)
