The commonly used e-procurement systems still show unsatisfactory implementation outcomes because many organisations are still unable to effectively interpret the initial adoption decision. The e-procurement systems are generally developed at organisational level, but their usage is at individual level, by the employees particularly. This paper examined technology acceptance model’s (TAM) key antecedents, involving e-procurement systems usage by employees in their daily activities. This study aims to examine the impact of factors affecting e-procurement acceptance among users through the mediating role of users’ attitude. The commonly used e-procurement systems still show.

TAM was applied and expanded in this study, in exploring the factors impacting the employees’ e-procurement acceptance. This study used quantitative method, and questionnaires were distributed to 200 users in Jordanian public shareholding firms. The collected data were quantitatively analysed using PLS modelling.

Significant TAM relationships involving e-procurement were affirmed. The expanded TAM in the scrutiny of antecedents showed that content, processing and usability affected perceived usefulness, while perceived convenience did not affect the usefulness factor. Furthermore, it was noticed that perceived ease of use was affected by usability and training, while perceived connectedness was not affected by usability and training.

The results demonstrated the necessity of e-procurement training. Furthermore, at the start of the implementation stage, effective design on system navigation and system usability, and consistent support, could increase use effectiveness and acceptance. Also, expedient information and buyer–supplier product flows should be made available.

Most organizations invest a lot of time and money in installing e-procurement systems to deliver their goods at the right time and at the right price. However, many of these e-procurement systems have failed due to low acceptance among users. Thus, to the best of the authors’ knowledge, this is the first study that used TAM and theory of planned behaviour in examining the effects of perceived convenience, perceived connectedness, content, training, processing and usability factors, in Jordanian firms. Lastly, the focus of this study was on the individual employee’s acceptance, rather than on the organisational-level adoption, as the unit of analysis, to provide insight on how organisations can achieve maximally from e-procurement investments and from other comparable technologies of e-supply chain management.

Most small- and medium-sized enterprises (SMEs) use some business management software to manage their daily operations. Ultimately they consider transitioning to an enterprise resources planning (ERP) system. However, implementing ERP system successfully is costly and complex, and often shows high disappointment rates or even abandonment due to need of fit with the business or social culture. In Jordan, large businesses have been using the ERP system for a long time, but SMEs usage of the system is relatively new. The purpose of this paper is to study the effect of ERP implementation success antecedents which consists of training, supportive leadership and ease of use on ERP implementation success itself through a mediating effect of user satisfaction.

Empirical data were collected using a survey questionnaire which was distributed to ERP users in Jordanian healthcare organizations. A total of 175 responses were collected and analyzed using structure equation modeling.

A significant relationship was found between these antecedents and ERP implementation success. Furthermore, user satisfaction plays a significant mediating role between ease of use and ERP implementation success.

The outcomes of this study are useful to ERP users as they would be able to strategize future ERP system implementation in different sectors such as education, manufacturing and insurance industry. Finally, the findings may be useful to ERP system adopters in different developing countries.

This is one of the first studies which adequately covers the relationships between antecedents of user satisfaction and ERP implementation success which consists of training, supportive leadership and ease of use on ERP implementation success itself through a mediating effect of user satisfaction.
