“…Complexity is an effort related to achievement of performance in accordance with predetermined objectives and reduce effects in the completion of complex tasks. Complexity is a problem-solving solution that comes from diverse and conflicting with performance, behavior, fault tolerance, security and dependency, Complexity is determined largely by the selection of business processes supported by the system or module to be implemented [14,16,30]. Complexity is used not only in special cases but also in the standard methodology used to manage information systems or systems management projects.…”

“…Complexity is further enhanced by cultures, different business processes, complex financial arrangements and possible political interventions by interested parties. Complexity is a significant problem for the managerial level and can impair operational performance if not managed properly or if managed properly can be used to gain strategic advantage [14]. ERP system is a complex software that becomes the reason to experience ERP implementation failure, that is because experiencing complexity in ERP implementation and have to do business process change [3].…”

Demand for the industry to enhance competitive advantage. For that, the industry is required to make a breaking through in order to enhance the organizational performance. This is a reason for addressing the inefficiencies in managing people, processes, organizations, and technology. One of the efforts in improving organization performance is the development in the field of Information Systems as an effort to improve the agility of the organization. ERP system is one solution that can be employed in order to improve organization performance. However, in reality, industrial companies face problems in ERP implementation. This is a challenge to solve the problems of implementing an ERP system for industry. In this opportunity, researchers intend to conduct a re-search to identify the problems of factors in the ERP implementation, namely by proposing agile methods as one of the new methodologies in the effort to solve the problems in the ERP implementation for an industry. The results of this study will result in an agile model of implementing ERP for improving the capacity of ERP systems. This study idea is to analyze the agile method as a solution alternative to make changes for the ERP implementation success. This study is using Structural Equation Modeling as a quantitative data analysis approach of an industry as a case study.

“…There are also publications dealing with the impacts of complexity on system security and maintainability. Their objective is to describe certain aspects of complexity [6] and/or to point out the negative impacts of complexity on the business [5]. The topic of managing information system complexity is discussed, for example, by John Maeda in his book "The Law of Simplicity", where he defines ten rules of simplicity [7].…”

Abstract. The paper discusses the reasons of complexity rise in ERP system SAP R/3. It proposes a method for measuring complexity of SAP. Based on this method, the computer program in ABAP for measuring complexity of particular SAP implementation is proposed as a tool for keeping ERP complexity under control. The main principle of the measurement method is counting the number of items or relations in the system. The proposed computer program is based on counting of records in organization tables in SAP. Keywords: Complexity, ERP, SAP, measurement, information system, business. IntroductionIn this paper we discuss the approaches to complexity and show that several methodologies used for Information and communication technology (ICT) and information systems (IS) management do not handle the topic of complexity well. Then we discuss the complexity of SAP ERP 1 system and the reasons for rising complexity in SAP implementations. Afterwards we propose a method and a program for measuring complexity of ERP systems and describe a verification of the method on a certain business case. There are several decisions during the lifecycle of an SAP System that influence the complexity of the systems. These decisions are made by project manager, by IT managers or by team members. The goal of our paper is to give a tool for the decision makers, which can measure the complexity at a certain point. It could be used by project manager or solution architect during the implementation to control the complexity and prevent the growth of it. Related Work on Measuring ComplexityA good theoretical basis for describing and exploring complexity can be found in the mathematical graph theory [1], [2], which can be applied to some IS/ICT models to facilitate their quantification and subsequent comparison and, in some cases, even their simplification. Publications that come closest to the topic of business information system complexity deal with using metrics to measure complexity, such as information flow metrics [3], Halstead's method or functional point analysis [4], or a simple number of source code lines [5]. These methods are focused on software development and are less suitable to handle SAP systems, where more settings are done by customization and system configuration. There are also publications dealing with the impacts of complexity on system security and maintainability. Their objective is to 1 SAP ERP -Enterprise Resource Planning software of SAP company (www.sap.com)
