Özet:

Today, businesses need to consider many parameters such as cost, quality, efficiency and being able to predict the changing business conditions in order to keep up with the competitive environment. Enterprise resource planning systems (ERP) connect daily business requirements such as accounting, procurement, project management, R&D (Research and Development), foreign trade operations with the necessary information. Although ERP systems have the feature of combining every data from all points of view of an enterprise, many companies cannot achieve the success they desire in these software that they purchase by bearing high costs. Accordingly, the aim of the study is to select the most suitable system for a company that decides to use an enterprise resource planning system, by using TOPSIS, one of the multi-criteria decision making methods. When the literature and qualitative study results were evaluated together in the study, the criteria such as system competence, system flexibility, cost, training, after-sales support and efficient project management criteria were determined to be the main ones. In order to determine the significance level of the criteria, a process of criteria weighting was executed with the senior managers of the company. At the end of the study, the most important criterion was determined as “cost” and “ERP 3” was selected as the ERP system with the highest score among the existing enterprise resource planning systems
