More
and more organizations are being run dependent on information systems. This
makes information systems a pivotal component of our lives. Because of
globalization and harsh competition, strategic cost management has become
essential to gain or keep competitive advantage. These two trends make
calculation of Total Cost of Ownership (TCO) of information systems crucial. To
this end, a TCO calculation framework, which can be extended according to the
requirements of an organization, is presented in this study. Thus, it is aimed
to support engineers to develop cost-effective information systems and/or to
apply different solutions to reduce costs of existing systems. A validity check
has been done with a case study, which describes the use of the framework in an
international company and provides an example of how to extend the framework.

Anahtar Kelimeler

information system, computer system, software intensive system, total cost of ownership (TCO)

Bilgi Sistemlerinin Toplam Sahip Olma Maliyetini Hesaplamak İçin Bir Çerçeve

Öz

Giderek
daha fazla sayıda organizasyonun faaliyetleri bilgi sistemlerine bağımlı duruma
gelmektedir. Bu da bilgi sistemlerini hayatımızın önemli bir bileşeni durumuna
getirmektedir. Küreselleşme ve zorlaşan rekabet nedeniyle, rekabet avantajı
elde etmek ya da bunu korumak için stratejik maliyet yönetimi vazgeçilmez bir
konuma gelmiştir. Bu iki eğilim, bilgi sistemlerinin toplam sahip olma
maliyetlerinin (TSOM) hesaplanmasını önemli kılmaktadır. Bu doğrultuda, bir
organizasyonun gereksinimleri doğrultusunda genişletilebilecek bir TSOM
hesaplama çerçevesi bu çalışma kapsamında sunulmuştur. Böylece mühendislerin
uygun maliyetli bilgi sistemleri geliştirmelerine ve/veya mevcut sistemlerin
maliyetlerini azaltmak için farklı çözümler uygulamalarına destek olunması
hedeflenmiştir. Çerçevenin, uluslararası bir şirkette kullanımını anlatan ve
nasıl genişletilebileceğine dair bir örnek oluşturan vaka çalışması ile
geçerlilik denetimi yapılmıştır.

Anahtar Kelimeler

bilgi sistemi, bilgisayar sistemi, yazılım yoğun sistem, toplam sahip olma maliyeti (TSOM)
