Abstract:

Etkinlik değeri işletmelerin başarı düzeylerinin ölçülmesinde kullanılan önemli araçlardan biridir. Ancak etkinlik değerinin ölçülmesi sırasında çok sayıda girdi ve çıktının birlikte düşünülmesi gereklidir. Birçok girdi ve çıktının birlikte incelenmesine imkan sağlayan tekniklerden biri veri zarflama analizidir. Bu çalışmada sırasıyla, Veri Zarflama Analizi (VZA) hakkında bilgi verilmiş, yöntemin matematiksel işleyişi açıklanmış, konu ile ilgili yapılmış çalışmalara değinilmiş ve BIST Bilişim endeksinde yer alan oniki firmanın etkinlik değerleri veri zarflama analizi (VZA) ile belirlenerek sonuçlar değerlendirilmiştir. Buna göre bazı firmaların çok düşük yatırımla oldukça tatminkar kazanç elde ettiği bazı firmaların ise tam tersine yüksek yatırıma rağmen oransal olarak karının düşük olduğu görülmüştür. Efficiency value is one of the important tools which is used for measuring success levels of the companies.
