An organization must restructure itself once it makes outsourcing decisions. Outsourcing is a strategy that a companyadopts to direct internal efforts into strengthening its core business processes while contracting other companies for strategicallyless critical tasks thereby improving organizational production efficiency, and the strategy inevitably involves organizationalrestructuring. While public service organizations have increasingly embraced outsourcing as well, only a handful ofstudies analyze the change in efficiency from organizational restructuring. Therefore, this study uses Stochastic FrontierAnalysis (SFA) to test whether efficiency improved in Korea Expressway Corporation’s restructured branch offices. KoreaExpressway Corporation evaluated and grouped its branches based on road extensions management, traffic volume, thenumber of snow days, road deterioration, and the number of junctions to differentially allocate its personnel and budget. The extent of efficiency improvement in each group was compared, and results show that inefficiency did not exist in anyof the groups. The efficiency index among the three group categories was similar across the board; 9 offices in the A-groupwith its expanded personnel and budget had an efficiency index of 0.954, 12 offices in the B-group with unchanged personneland budget conditions had an index of 0.950, and 12 offices in the C-group with reduced personnel and budget had anindex of 0.937. SFA facilitates efficiency analyses because it does not require pre-restructuring data. This study is easyto apply in practice and empirically tests efficiency improvement in organizational restructuring based on data collected fromall the branch offices in Korea Expressway Corporation.
