Παράγοντες μη επιτυχούς υλοποίησης ERP συστημάτων
In the current framework of competition and constant changes, businesses are facing many important challenges. Businesses are interested to support their competitiveness and to protect themselves against possible risks. This caused the need for development of Enterprise Resource Management Information Systems. The present research has to do with the study of important business’s survival and development issues in the modern society of technology information, focusing on Business Resource Management systems. Business Resource Management Systems, or else ERPs, integrate all of the enterprise's operations into a common platform in which the search for management and exploitation of information becomes easy. They are considered by businesses as the best technological solution for more efficient and effective information management. The high probability of failure combined with the great demands on resources, such as financial, material and human, has attracted the interest of the researchers. While ERP systems designed for large companies over the last few years, they have also become dynamic in small and medium-sized businesses. The implementation of such systems with the least possible risk is of paramount importance. The thesis is developed in six chapters. Initially, we present an introduction to basic concepts of ERP systems to highlight their key features. Then, we study the importance of their role in modern businesses and their usefulness by analyzing key operational programs. Next, we describe the process of selecting and implementing an information system as well as its influence on both Logistics and other important functions such as production, human resources, sales and marketing. If such a system is properly selected and implemented, it can lead to a more efficient and effective operation of the business. The most important point is to identify the factors that affect the implementation of an information system positively and mainly negatively. The main objective of the work is to evaluate the cost, the benefits and the overall return on investment. In the last part, having collected the data from some surveys and using the SPSS program, we present the results of enterprises that have been damaged by the use of ERP systems. The goal is, through the results, to elucidate important elements and factors that were directly involved in the implementation process and also, which factor played a decisive role and which program is the one that presents the most drawbacks. Attempts are made to provide suggestions and solutions to correct or avoid them. Having an overview of the above, this paper closes with some conclusions as to whether the adoption of an ERP system in a business is worthwhile.
