Effects of BPR on ERP Implementation Success and Supply Chain Performance
(Acad Conferences Ltd, 2012) Erkan, Erman; Bac, Ugur; Rouyendegh, Babak Daneshvar
Recently, studies about the Enterprise Resource Planning (ERP) have been increased and this research area has attracted more attention. Especially, in the global competition environment, enterprises have to focus on their Information Systems (IS) performance to have a competitive advantage; implementing an ERP system and improving the effectiveness of the system is the only way. To do so; factors affecting the implementation success of ERP systems have to be inspected in pursuant of some performance measurements and metrics. Since unsuccessful ERP implementations result in high costs; use of these factors and making the necessary preparations will increase the chance of a successful ERP implementation. According to literature Business Process Reengineering (BPR) has a vital role on the ERP success. In this study, a research has been made on the Turkish enterprises to determine the criteria affecting their success on the implementation of ERP systems by the utilization of a questionnaire. Questionnaire results have been analyzed with statistical methods to summarize the current situation of IS structure, Information Management Systems integration level, ERP success rate and effects of BPR on this success rate in Turkish enterprises. Results of this study can be used to define the relation between the ERP and BPR. Understanding this relation is vital for the planned or ongoing ERP implementations. Factors and criteria found in this study which have effects on the ERP systems success should be considered during the implementation planning phase of these systems for efficiently managing the budget of projects. Importance of BPR which was emphasized in this study should be considered by the management of enterprises for evaluating their IS to determine if they are ready for the implementation phase. If they are not, findings will serve as a guideline for improving the chance of successful implementation and this will affect overall performance of the company. Results of this study can also be used in the future studies to compare international differences of IS structures and ERP implementation processes.
Enterprise Resource Planning Implementation Differences Within the Same Methodology - Case Study From West Europe and Turkey
(Acad Conferences Ltd, 2011) Erkan, Turan Erman
Enterprise Resource Planning (ERP) systems are vital for competitive edge in today's business world. ERP is an integrated information system that serves all departments within an enterprise. Therefore, business processes should be optimised before ERP implementation in order to catch a perfect implementation. Before year 2000 all the giant firms realised their ERP projects and after that best practises took place. After those trial and error based experiences, ERP vendors need to form an ERP implementation methodology. Big ERP vendors developed implementation methodologies, they were almost the same; starting from project preparation to selection, implementation to maintenance and control. Those project methodologies improved the success rate of ERP implementations. This research is both empirical and qualitative. In fact it consists of two monographic researches. They are both about ERP implementations in the same sector. One of the firms is a national one and other one is a multinational one. Both implementations done by the same consultant team with the same methodology, so the evaluation of the project is more objective than any other questionnaire based ones, which are filled by different implementation teams. The findings of the comparison are surprisingly different from each other within the implementations, although they both used the same methodology. Basic steps of the ERP implementation such as: project preparation, business blueprint, realization, final preparation and go live & support differs from each other both in national and multinational firms. The major difference is seen in the first steps which are project preparation and business blueprint. Multinational firm seems to have more chance than the national one in achieving organisational efficiency through successful ERP implementation. The research outcome is useful for professionals running implementation projects and those making decisions on ERP implementation. The results can also be used by practitioners managing ERP projects in order to avoid from implementation methodology illusion.
An Evaluation of Using Innovative Information Systems in Local Governments in Turkey: the Case of Cankaya Municipality
(Acad Conferences Ltd, 2012) Sahin, Savas Zafer; Erkan, Turan Erman; Cekic, Anil
In the last three decades, waves of globalization caused an upsurge of interest about localities and local governments with respect to various factors of production and consumption. Turkish case is no exception to this change. Beginning with 2000's, Turkish government initiated a new program for a renewed distribution of authorities between central and local governments resulting in rescaling of Turkish state. New authorities and responsibilities were decentralized to local governments. As the local governments in Turkey became the locus of all political activities, debates concerning institutional capacity of them became wide-spread. It has been widely argued that although increasing number of authorities were transferred to local governments; they lack necessary institutional capacity and know-how to manage increasing number of responsibilities and changing spatial structure. For this respect, the problem with local governments in Turkey has three facets. First of all, decision-making mechanisms of local governments is weak, both process wise and with regards to rationality, accountability and transparency. Mostly, political patronage is more influential than good governance. Secondly, implementation level of innovative information systems in decision making-mechanism with regards to spatial issues, service production and public participation is poor. For instance, although information systems like UIS (Urban Information systems), IAM (Intangible Asset Management), IRP etc. are used, they are either poorly integrated to management system or became obsolete because of lack of proper performance measurement and evaluation. In Turkish case there is a clear gap between management practices of local government service delivery and use of innovative information systems. In this paper, it is aimed to portray the underlying dynamics and problems behind ineffective use of innovative information systems in local governments in Turkey. For this purpose, one of the largest and well-known district municipalities of Turkey, Cankaya Municipality in Ankara is taken for a case study. Cankaya Municipality's technological capacity and use of innovative information systems is assessed in terms of accountability, decision-making, and public participation. Results of the assessment will be used to develop some strategies and tools for improving municipality's capacity to make better use of information systems.

A Fuzzy Ahp for Evaluation of Ecommerce Websites Performance
(Acad Conferences Ltd, 2012) ictenbas, Burcu Devrim; Rouyendegh, Babak Daneshvar
eCommerce has become an essential part of business strategy in the rising (emerging) global economy. In order to be successful in the eCommerce marketplace, organizations will need to provide high quality websites that attract and retain users. It is a need to understand and evaluate eCommerce websites to achieve high quality. Evaluation of eCommerce websites is a multiple criteria decision making (MCDM) problem since it includes analysis of both qualitative and quantitative factors. Also human judgment has taken part in this process. This paper presents FAHP to evaluate three eCommerce websites. The results will be a guide for decision makers in terms of improvable areas to design eCommerce websites.
Intellectual Capital Management's Effects on Enterprise Resource Planning Implementation
(Acad Conferences Ltd, 2012) Erkan, Turan Erman; Ozdemir, Yavuz Selim; Bac, Ugur
The implementation of an Enterprise Resource Planning (ERP) system can be one of the most important strategic decisions an organization undertakes. An implementation of ERP system has effects on improving all over system performance. However, there are many factors affecting the performance of ERP implementation and these factors have to be inspected in accordance to some performance measurements and metrics. Intellectual Capital Management (ICM) is one of the most important factors of ERP implementation. The ICM literature has produced tens of models to support the various ICM activities, such as identification, measurement, valuation, acquisition and reporting of intellectual capital. However, the practice of applying various ICM models seems to be a fairly new issue in many countries and organizations. Turkey is one of those countries that has just been introduced with ICM. Using an ICM system has different effects on the implementation of an ERP system. In this study, a questionnaire based research has been made on Turkish enterprises to analyze ICM'S effects on ERP implementation. Also, we made a cross industrial research and determined those effects in different manufacturing sectors such as electronics and food sectors. Questionnaire results have been analyzed with statistical methods to summarize the current situation. The results of this study can be used to compare the effects of implementation of ERP systems in different industries in Turkey. Understanding of this relationship is very important for current or future ERP implementations. Also these results can be used in the comparison of international differences of the effects of ICM on ERP implementation process.
Selection of Erp System Using Qfd Approach: a Pilot Study From Turkey
(Acad Conferences Ltd, 2012) Ictenbas, Burcu Devrim; Rouyendegh, Babak Daneshvar; Erkan, Turan Erman
Today companies face the challenge of increasing competition, expanding markets and rising competition. Many organizations seek to improve their competitiveness by utilizing advanced information technology, such as Enterprise Resource Planning (ERP) systems. Selection of appropriate ERP system is a vital decision for any enterprise in this intense competitive environment. The selection process is complicated since complexity of ERP systems and too many alternatives. Requirements analysis of a software system like ERP is often considered to be one of the most important steps in the software selection process. Quality Function Deployment (QFD) is a methodology to translate customer requirements into the final product or service characteristics. In spite of successful applications of QFD in familiar fields such as product planning, education quality and service quality, the usability of QFD in the selection of software systems have been seen in only few studies. The purpose of the study is to determinethe most important technical attributes of the ERP systems from the end - users' perspective using QFD methodology. The developed framework integrates ERP characteristics obtained from vendors in the market and the list of customer requirements by taking into account the company profile and strategic selection criteria. The solution proposed in this study will support decision makers to manage the early stages of ERP selection according the company's needs.
