This literature review paper summarizes the state-of-the-art research on big data analytics. Due to massive amount of data exchanged everyday and the increased need for better data-based decision, businesses nowadays are looking for ways to efficiently manage, and optimize these huge datasets. Moreover, because of globalization, partnerships, value networks, emergence of social networks, and the huge information flow across and within enterprises, more and more businesses are interested in utilizing big data analytics. The main focus of this paper is to elucidate knowledge on the characteristics of big data analytics literature as well as explore the areas that lack sufficient research within the big data analytics domain, suggest future research avenues, as well as, present the current research findings that could aid practitioners, researchers, and vendors when embarking on big data analytics projects. Towards that end, we have reviewed 24 publications between 2010 and 2014. Results of text mining the papers revealed that they belong to three clusters with both common as well as distinct characteristics. The reviewed papers were clustered into three main themes, 1) technical algorithsms; 2) processing, cloud computing, opportunities & challenges; and 3) performance, prediction, and distributed systems.

The Future of ERP Systems : look backward before moving forward
2012
Ingår i: Procedia Technology. - : Elsevier BV. - 2212-0173. ; 5, s. 21-30
Tidskriftsartikel (refereegranskat) abstract
This paper explores the enterprise resource planning (ERP) systems literature in an attempt to elucidate knowledge to help us see the future of ERP systems' research. The main purpose of this research is to study the development of ERP systems and other related areas in order to reach the constructs of mainstream literature. The analysis of literature has helped us to reach the key constructs of an as-is scenario, those are: history and development of ERP systems, the implementation life cycle, critical success factors and project management, and benefits and costs. However, the to-be scenario calls for more up-to-date research constructs of ERP systems integrating the following constructs: social networks, cloud computing, enterprise 2.0, and decision 2.0. In the end, the conclusion section will establish the link between the as-is and to-be scenarios opening the door for more novel ERP research areas

The impact of ERP partnership formation regulations on the failure of ERP implementations
2013
Ingår i: Procedia Technology. - : Elsevier BV. - 2212-0173. ; 9, s. 527-535
Tidskriftsartikel (refereegranskat) abstract
According to statistics, majority of ERP implementations fail. Failure means either total cancellation of the project, or failure to go-live on time and/or within budget constraints. Mainstream literature focuses on different reasons for failure including poor project management, resistance to change, lack of top management support, insufficient user training, etc. In this research we focus on the impact of vendor-partner relationship on the failure of ERP implementations. Some vendors provide easy terms and conditions in order to attract new partners and develop a wider network of partners in the targeted regions. In this study, the terms and conditions of SAP for certifying partners are studies and analyzed. In addition, case studies of two SAP partners are conducted. The primary research results suggest that the easy partnership conditions set by ERP vendors are among the main contributing factors for ERP projects failure in our cases. This finding is considered novel since most of the related work attributes failures to other factors, ignoring the vendor-partner terms and conditions.

The use of experts panels in ERP cost estimation research
2010
Ingår i: ENTERprise Information Systems. - Berlin : Encyclopedia of Global Archaeology/Springer Verlag. - 9783642164187 - 9783642164194 ; , s. 97-108
Konferensbidrag (refereegranskat) abstract
This paper is an effort towards illustrating the use of expert panel (EP) as a mean of eliciting knowledge from a group of enterprise resource planning (ERP) experts as an exploratory research. The development of a cost estimation model (CEM) for ERP adoptions is very crucial for research and practice, and that was the main reason behind the willingness of experts to participate in this research. The use of EP was very beneficial as it involved various data collection and visualisation techniques, as well as data validation and confirmation. Beside its advantages, one of the main motives for using a group technique is that it is difficult to find a representative sample for a casual survey method, as ERP experts and consultants are rare to find, especially in the scope of SMEs' ERP implementations. It is worth noting that the panel reached consensus regarding the results of the EP. The experts modified and enhanced the initial cost drivers (CD) list largely, as they added, modified, merged and split different costs drivers. In addition, the experts added CF (sub-factors) that could influence or affect each cost driver. Moreover, they ranked the CD according to their weight on total costs. All of this helped the authors to better understand relationships among various CF

ERP adoption cost factors identification and classification : a study in SMEs
2013
Ingår i: International Journal of Information Systems and Project Management. - 2182-7796 .- 2182-7788. ; 1:2, s. 5-21
Tidskriftsartikel (refereegranskat) abstract
Enterprise resource planning (ERP) systems adoptions require substantial resources and investments. The majority of businesses around the globe can be considered to be small and medium sized enterprises (SMEs). Thus, SMEs are seen to be typical companies that are the cornerstone of most economies. Compared with large enterprises, an SME-context contains several characteristics, and scarcity of resources is among the top of them. For SMEs, unplanned costs escalation could pose a serious threat to their stability and survival in the market. Frequently, ERP projects have crossed their estimated budgets and schedules. Researchers and practitioners state that a prevailing number of ERP adoption projects fail due to inaccurate or to too optimistic budgets/schedules. In addition, many organizations face difficulties in identifying the potential cost factors that could occur during their ERP adoption lifecycle. While focusing on the SME-context, this research attempts to identify potential costs that could occur in ERP adoptions. The research method employed in this study targeted diverse stakeholders and experts involved in ERP projects in Egypt. This research provides a list of cost factors and their classifications that could aid adopting organizations to better estimate their needed ERP project budgets. In particular, this research explores the direct and indirect cost factors that occur in ERP adoptions in Egyptian SMEs. Also, this study investigates the influence of some SME-specific contextual factors on costs. Moreover, the paper provides a ranking of cost factors according to their impact on total adoption costs.

ERP adoption cost factors in SMEs
2011
Ingår i: Proceedings of the European, Mediterranean and Middle Eastern Conference on Information Systems. - : Information Systems Evaluation and Integration Group. - 9781902316857 ; , s. 130-141

Small and medium enterprises (SMEs) have limited budgets, resources, and great sensitivity to costs. When SMEs take the first step into implementing an enterprise resource planning (ERP) system, they need to think about many things, foremost the cost of adoption. Most ERP implementations fail due to inaccurate and optimistic budget and schedule estimations, as well as, anticipating indirect costs beforehand is problematic. With the deficiency of a clear model of cost factors for ERP adoptions, ERP adoptions face a high risk of failure Failures could be caused by several factors, but the scope of this research is focused on studying the factors that escalate costs. This could aid SMEs in visualizing the different expected costs, and would consequently assist in better future cost management and estimations. There has been plenty of research in ERP; however, a clear gap in ERP cost management and estimation exists. This paper focuses on identifying direct and indirect cost factors that influence total costs in the ERP adoption process. The paper presents a cost list that has been developed through literature and an ERP expert panel. Furthermore, this study validated the costs list through interviews with different stakeholders within ERP adoption projects in Egypt.

A lot of research has been undertaken focusing on ERP systems lifecycles, but very little paid attention to retirement. ERP retirement means the replacement of an ERP with another. The aim of this research paper is to investigate why and when should organizations retire their ERP systems. A convenience case study of an SME has been selected from Egypt. The case study under investigation has retired their local ERP system and replaced it with SAP ERP. Results of our analysis indicated that reasons of retirement were: wrong selection, users were not involved in the selection process, and lack of an official implementation methodology. This is considered a new finding since main stream literature was mainly focused on retirement after maturity
