Evaluating the Technical Efficiency of Academic Departments: a DEA-Biplot Approach

This study proposes an innovative two-sta-ge approach, using Data Envelopment Analysis and Biplot, to evaluate the techni-cal efficiency of 30 academic departments a Chilean university, identify main factors affecting their performan-ces. Public higher education worldwide is under growing pressure increase improve quality edu-cation with limited governmental funds given state-owned universities. The ri-gorous supervision regulations make use decision-making approaches for rationale administration financial resources imperative. first stage used output-oriented DEA model, 3 con-figurations assumption that units analysis have more influence on producing outputs than generating income. second employed Bi-plot characterize depart-ments into four clusters, external variables influencing (in)effi-ciency scores. Results indicated acade-mic focused teaching are efficient those aiming re-search. Among level performance were num-ber full-time equivalent faculty holding graduate studies, average course approval ratio.
