Complexity impact factors on the integration process of ERP and non ERP systems: a basis for an evaluation instrument

This study shows an expert confirmed initial list of factors which influence the complexity of the integration process of ERP systems and non ERP systems. After a thorough search for complexity factors in scientific literature, a survey amongst 8 experts in a leading European long special steel products company, which was recently composed out of independent international companies, was conducted. The participants confirmed the retrieved list from literature, consisting of 5 quantitative and 21 qualitative factors. The participants added one extra qualitative factor and scored the importance of all factors. Three quantitative factors, i.e. a technology, a business and a project factor, scored highest. When dealing with integration issues, this initial list of factors can provide awareness for organizations to support activities such as planning, control and risk management
