Bilgi Sistemlerinin Toplam Sahip Olma Maliyetinin Mevcut Durumu Üzerine Bir Sistematik Haritalama Çalışması

Giderek daha fazla sayıda organizasyonun faaliyetleri bilgi sistemlerine bağımlı duruma gelmektedir. Bu da bilgi sistemlerini hayatımızın önemli bir bileşeni durumuna getirmektedir. Küreselleşme ve sert rekabet koşulları 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 maliyetinin (TSOM) hesaplanmasını önemli kılmaktadır. Bu amaçla, bilgi sistemleri bağlamında TSOM kullanımını irdelemek için bir sistematik haritalama çalışması sunulmuştur. Konuyla ilgili 75 yayın analiz edildikten ve sentezlendikten sonra elde edilen bulguların bir özeti şu şekildedir: (1) bilgi sistemleri için TSOM’a yıllar boyunca artan bir ilgi gözlemlenmektedir; (2) seçilen yayınların %76’sı geçerlilik ve değerlendirme eksikliği taşımaktadır; (3) yayınların %72’sinin arkasındaki en büyük motivasyon, TSOM’un azaltılmasıdır; (4) TSOM’u azaltmanın vazgeçilmez araçları bulut bilişim, servis olarak yazılım modeli ve çoklu kiracılıktır; (5) TSOM hesaplamaları genellikle bulut tabanlı altyapıları kurum içindeki altyapılarla ve servis olarak yazılım modeli ile kurum içi yazılımları karşılaştırmak için yapılmaktadır; (6) TSOM, bilgi sistemleri için (kurumsal kaynak planlama, müşteri ilişkileri yönetimi sistemleri gibi) yatırım kararlarında önemli bir kriterdir.

A Systematic Mapping Study on the Current Status of Total Cost of Ownership for Information Systems

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 keep or gain competitive advantage. These two trends make the investigation of Total Cost of Ownership (TCO) for information systems crucial. To this end, a systematic mapping study (SMS) is presented to identify the use of TCO in information systems context. A summary of the findings after analyzing and synthesizing 75 relevant publications are as follows: (1) an increased interest in TCO for information systems is observed over the years; (2) 76% of the selected publications lack validation and evaluation; (3) the main motivation behind the 72% of the publications is reduction of TCO; (4) essential means of reducing TCO are cloud computing, SaaS model, and multi-tenancy; (5) TCO calculations are also generally made to compare cloud-based infrastructures with in-house infrastructures and SaaS model with on-premise software; (6) TCO is an important criterion in making investment decisions for information systems such as ERP, CRM.
