The success of Enterprise Resource Planning (ERP) implementation depends, to a large extent, on end-users' acceptance of ERP systems, which in turn affects the intensity and nature of system use. To understand the phenomenon underlying end-users' acceptance of ERP systems, the authors conducted a grounded theory research in a large institution that implemented an ERP system. Through systematic coding and content analysis, the authors inductively derived a theoretical model to explain end-users' acceptance of ERP systems. Three categories – beliefs about the system, changes in job scope, and social influence – emerged from the data as direct antecedents of user acceptance. The data also suggest that “beliefs about the system” mediates the influence of “training and support” and “personal characteristics” on user acceptance, whereas “personal characteristics” moderate the influence of “changes in job scope” on user acceptance. The theoretical model that emerged from this qualitative study extends existing models of user acceptance by providing a more complete understanding of end-users' acceptance of ERP systems.

Perkembangan ekonomi yang semakin cepat menyebabkan persaingan bisnis yang semakin ketat. Apalagi dengan adanya perkembangan teknologi yang semakin canggih, perusahaan-perusahaan tersebut berlomba-lomba dalam memanfaatkan teknologi untuk meningkatkan keunggulan kompetitif dan efisiensi kinerja perusahaan mereka dibandingkan pesaingnya. Salah satu investasi teknologi informasi yang populer saat ini adalah sistem Enterprise Resource Planning (ERP) yaitu paket aplikasi yang menawarkan ”best practice” dalam menjalankan bisnis dengan menggunakan satu basis data yang dapat diakses oleh semua divisi dalam perusahaan. Terdapat banyak keuntungan yang dapat dirasakan oleh perusahaan dengan mengimplementasi sistem ERP, seperti mengurangi biaya produksi, meningkatkan integrasi data, dan mengurangi level inventori. Namun, sebagian besar implementasi sistem ERP yang telah dilakukan oleh beberapa perusahaan mengalami kegagalan. Salah satu faktor yang menyebabkan kegagalan ini adalah adanya resistensi pengguna terhadap perubahan. Resistensi dari pengguna ini juga menyebabkan perusahaan tidak dapat memaksimalkan keuntungan dari implementasi sistem ERP. Oleh karena itu, paper ini akan membahas mengenai faktor-faktor yang memengaruhi penerimaan pengguna dalam menggunakan sistem ERP. Faktor-faktor penerimaan ini didasarkan pada model penerimaan pengguna yang sudah ada pada penelitian sebelumnya yaitu model Unified Theory of Acceptance and Usage of Technology (UTAUT). An increasingly rapid economic development led to the increasingly stringent business competition. Especially with the development of increasingly sophisticated technology, these companies are competing in utilizing technology to enhance competitive advantage and efficiency of their company's performance than its competitors. One of the investment in information technology that is popular today is the Enterprise Resource Planning (ERP) system, is an application package that offers best practice of doing business by using a single database that is accessible by all divisions within the company. There are many advantages that can be felt by companies to implement ERP systems, such as reducing production costs, improve data integration, and reduce inventory levels. However, most implementations of ERP systems that have been done by some companies to fail. One of the factors that caused this failure is the presence of user resistance to change. Resistance from users has also led the company can not maximize the benefits of ERP system implementation. Therefore, this paper will discuss the factors affecting user acceptance of ERP systems in use. Acceptance factors are based on the user acceptance model that already exists in previous studies that model the Unified Theory of Acceptance and Usage of Technology (UTAUT).

Successful implementation of ERP systems should take full advantage of the access to information, but not be constrained by many of the deficiencies associated with infinite capacity scheduling methodologies. In this paper an algorithm is developed which improves the performance of the ERP system. Lot sizing decisions based on capacity availability are used as an instrument to integrate more effectively capacity requirements planning (CRP) and Material Requirements Planning (MRP). MRP is a planning tool for a sub-set of manufacturing system specially in hierarchal multi-product, multi-period and multi-stage production planning and inventory control system. The Vehicle used for this integration is planned order release (POR) quantity. The algorithm requires minimal deviation from the MRP logic. In this sequential process MRP first issues the action notices and then the algorithm analyses the capacity situation in the work centers. The algorithm scans all planned order release quantities of lower level items in the action bucket before orders are released to the shop. For each item a delta value is computed identifying the degree orders are contributing to capacity problems. This delta is specific to each POR. The POR causing the highest overload and the one passing through the lowest utilized work centers are selected for a lot size decrease, respectively, an increase. After identifying the candidates, a series of checks analyses the suitability of the candidates for that change. The planned order release quantities of more items can be performed. Projected capacity profile after iteration will be updated and capacity requirements over a short duration are smoothed. The experiments are performed with MAP/3000 as a simulation model for this study. The developed algorithm is added to MAP/3000 as additional subroutines. The design of the experiments consists of a base test identifying the significance of different environmental parameters of MRP systems and a main test which performs a detailed evaluation. The results are evaluated using analysis of variance techniques. Most ERP systems built on the historical development of MRP and CRP systems, and the assumption of infinite capacity is affecting the performance of those systems badly. This paper is presenting an algorithm to smooth capacity problems by using the existed capacity.

The enterprise resource planning (ERP) system can integrate the major business management functions of the enterprise with a single common database to allow sharing of all information and achieve efficient communications between management functions. Based on the needs of running a construction enterprise, ERP shows potential applicability to the construction industry. This paper sought to quantify the benefits of ERP systems when applied to construction materials procurement. Specifically, this paper briefly described the business processes involved in construction materials procurement and illustrated how ERP systems could be implemented and the efficiency of the construction materials management system consequently enhanced. The transformation from a non-ERP system into an ERP system through application integration, internal integration, external integration, and automation were simulated. Results show that the individual task improvements of models can increase the productivity of the materials management cycle by up to 5.2%, 18.2%, 27.8%, 13.5%, and 79.2% through internal integration, external integration, application integration, automation, and ERP system, respectively, by automating most of the repeated transactions and reducing manpower required to perform the tasks.Key words: enterprise resource planning, materials management system, productivity, simulation.

This paper uses a database, derived from a data repository, in order to do an analysis of enterprise resource planning (ERP) system benefits. ERP benefits are important for a number of reasons, including establishing a match between what ERP systems benefits are—as compared to ERP expectations—setting a benchmark for other firms, and measuring those benefits. ERP benefits also are central to the business case for deciding whether a firm will invest in an ERP system. It is found that some benefits vary across industry, while others seem to be important to firms independent of industry. In particular, tangible benefits are largely industry-independent, while intangible benefits vary across industry. In addition, when compared to an earlier study by Deloitte Consulting, the results are statistically consistent with their findings, but find substantial additional intangible benefits.

Organizations require to enhance their firm level resources to compete in turbulent business environment. Strategic application systems, such as an Enterprise Resource Planning (ERP) System is one such resource technology that centralizes the database of the organization to enable a seamless view of the organization. However, implementation of ERP systems in organizations has not been a success story for many. ERP systems implementation brings about large scale organizational change and hence it becomes essential for stakeholders to have a reference framework for planning for various dimensions of the organization. Hence this chapter applies a General Morphological Analysis(GMA) to identify the most suitable theory to analyse ERP implementation. Socio technical theory with Leavitt's diamond model was analysed as most appropriate since they are based on the of premises organizational change at firm level. Socio technical organizational change model will enable stakeholders to analyse resources required for core dimensions of the organization for ERP implementation.

When business managers are considering whether to invest in an enterprise resource planning (ERP) system, they ask the question: “What are the returns on investment?” When the ERP system is implemented and in operation, business managers ask another question: “How successful is the system?” To answer these questions, clues can be found by examining organizational effectiveness improvements as a result of ERP system implementation. This paper suggests that being able to identify the dimensions of organizational effectiveness is enabled by ERP systems. Together with positive organizational effectiveness improvements, the business value of ERP systems can be demonstrated. To provide the evidence needed to support the notion, a confirmatory factor analysis (CFA) was conducted. Analyses reveal that the construct of IS-enabled organizational effectiveness can be modeled, at a higher-order abstraction level, as a third-order construct manifested by three second-order constructs and ten first-order constructs.

Enterprise Resource Planning (ERP) systems have been recognized as complex and costly, which limited their implementation in large organizations. However, an increasing number of small organizations have recently gained interest in this system. This paper investigates the implementation process of ERP in a small firm. The investigation focused on two perspectives of ERP implementation: successes achieved and problems encountered. Despite many problems encountered in the firm, the ERP system still exists. This gives evidence that small organizations are more flexible and motivated to adapt to change and implement an ERP system. Most problems were encountered at early stages of implementation, which can be minimized if deliberate decision making of ERP implementation and proper selection processes were in place. Further, ERP is a good solution for small organizations if they are able to build a relevant in-house system.

The enterprise resource planning (ERP) system is a complex and comprehensive software that integrates various enterprise functions and resources. Although ERP systems have been depicted as a solution in many organizations, there are many negative reports on ERP success, benefits, and effect on user performance. Previous research noted that there is a lack of knowledge and awareness of ERP systems and their overall value to ERP organizations. ERP systems have been widely studied during the past decade; yet they often fail to deliver the intended benefits originally expected. One notable reason for their failures is the lack of understanding in user requirements. There are many studies conducted to propose software quality models with their quality characteristics. However, there is currently no dedicated software quality model that can describe usability maturity and involve new features of ERP systems. This chapter proposes a framework for evaluating the usability maturity as a quality attribute of ERP systems.


Enterprise Resource Planning (ERP) systems are implemented in companies to improve their business processes. An ERP system entails extensive functional and technological aspects during its implementation. Teaching ERP systems for computer science students implies addressing these two aspects: ERP functionality and technological features. It is a challenge for teachers to design practical experimentation that students can perform in the teaching environment, due to the prerequisite of a deep understanding of the business processes, business user requirements, and the technological complexity of ERP systems. In order to improve student skills in ERP systems, we encourage active learning among students. In this chapter, we present a methodology using open and closed practicals to learn about both technical and functional aspects of ERP systems. Using these practicals allows us to prepare and organize this teaching/ learning process.
