Bilişim teknolojisi yatırımlarının değerlendirilmesine yönelik uygun yöntemin seçilmesi modeli-ERP yazılımı seçimi uygulaması

Bilişim Teknolojisi (BT) yatırımlarının fayda ve maliyetlerinin büyük bir kısmı, kolayca sayısallaştınlamamaktadır. Bu yüzden sadece finansal tekniklerle değerlendirildiklerinde, pek çokflnansal olmayan fayda ve maliyetlerin hesaba katılmamış olması nedeniyle, sonuçlar, işletme yetkililerinin doğru kararlar almasına yardımcı olamaz. Bu çalışmada, işletmenin yapısına, istek ve önceliklerine, ve yatırımın türüne göre kullanılabilecek en uygun değerlendirme yönteminin seçilmesi için bir model önerilmektedir. Literatür taraması sonunda seçilen 45 farklı BT değerlendirme yöntemi detaylı olarak incelenmiştir. İşletmenin yapısını, isteklerini ve yatırımın türünü gösteren kriterler belirlenmiştir. Yöntemlerin, bu kriterlerin hangi düzeyinde kullanılabileceği, model önerisiyle sunulmuştur. Modelin uygulanacağı işletmenin, kriterler hakkında verdiği bilgiler değerlendirmeye alınarak uygun yöntem listesi hazırlanmıştır.

A model for selecting appropriate techniques for information techonology investment evaluation-an application on ERP software selection

In this study, a model for selecting technique(s) which is/are most appropriate for a given company's characteristics, needs and the investment type at hand, is proposed. 45 assessment techniques were examined in detail and eleven criteria were chosen to distinguish the evaluation methods from each other. A form having the 45 Information Technology (IT) investment evaluation techniques in the rows and, eleven criteria (stage of investment, investment type, type of benefits and costs, method simplicity, importance of numbers, company leadership role, industry situation, degree of predictability, type of impact, nature of investment and system/business relationship) and their levels in the columns is designed. IT evaluation professionals from all around the world, filled the form by marking the levels at which the techniques can be used. After examining the table established with the help of the answers received, two criteria (nature of investment and system/business relationship) that have no effect in distinguishing the techniques from each other are eliminated. The final model is formed by using the remaining nine criteria and the 45 methods. The model is applied on ERP (Enterprise Resource Planning) software selection. Evaluation methods are eliminated according to the criteria levels determined by the IT manager of the selected company. Then, they are ranked according to Saaty 's eigenvector methodology and are proposed to the company.
