According to Doug Braddock, supervisory economist at the BLS, Office of Occupational Statistics and Employment Projections, advances in purchasing automation and information technology are the likely causes of slower employment growth in the public-sector purchasing work force.
,The use of the Internet to conduct electronic commerce has made information easier to obtain, thus increasing the productivity of purchasing managers.The Internet also allows both large and small companies to bid on contracts,, Braddock said. ,Exclusive supply contracts and long-term contracting have allowed organizations to negotiate with fewer suppliers less frequently.,
Some readers may question the low number of purchasing managers, especially within state government.According to Braddock
, the relatively low number of purchasing managers in state governments may be connected to the Standard Occupational Classification definition of ,purchasing manager.,
,Employers are given the definitions and are asked how many are employed in that capacity,, Braddock said. ,Presumably, by the definition, there just aren,t that many purchasing managers in state governments.,
