Purpose Decision-making and problem-solving are ongoing progressions of evaluating situations or problems, considering substitutes, making choices and following them up with the necessary actions. The relationship between managers’ decision-making and information technology (IT) has long been of interest to researchers. This study aims to examine the changes in novel technologies in facilitating managers’ decisions that influence the quality and timeliness of information and decision-making. Design/methodology/approach The present paper is a descriptive-correlative study in terms of the data collection method and is applicable in terms of purpose. In addition, the library-field method was used to collect information. Because of the target and subject of the research of the statistical population, this research contains all managers of a management organization that are 100 people. The present study is used in the structural equation modeling method to examine causal models and evaluate the reliability and validity of the measurement model. The presented model and the gathered information from the questionnaires were analyzed through SmartPLS software. Findings The results indicate that the IT infrastructure, expert systems, marketing information systems (ISs) and organizational variables significantly influence the ease of managers’ decision-making and considering these dimensions is a step in the success of managers’ decisions. Research limitations/implications This study used a questionnaire to collect information, which may result in some people refusing to provide a real answer and giving an unrealistic answer. This study is also cross-sectional, and therefore, makes it difficult to conclude about causality. In addition, access to statistics and information is one of the significant pillars of research. Practical implications The paper presents useful advice for improving decision-making. In addition, the topic is relevant to the ease of managers’ decisions. A better understanding of the impact of IT infrastructure, expert systems, marketing ISs and organizational variables could significantly enhance managers’ success. Originality/value The ideas and topics discussed are equally applicable to libraries and can provide new insights into the impact of IT infrastructures, expert systems, marketing ISs and organizational variables on the ease of decision makers as a source of competition.

Purpose Nowadays, the Internet of Things (IoT) offers new intelligent services and business model opportunities by extending the internet connectivity into physical devices and daily objects. Recently, this technology has had a deep impact on all the aspects of human societies from industry to management and business. Therefore, the purpose of this paper is to predict the impact of using IoT services on the development of electronic business (e-business). Design/methodology/approach For evaluating the model’s elements, a questionnaire was designed. It was revised by experts with significant experiences. For statistical analysis, SmartPLS 3.2 is used. Findings The findings have confirmed the validity of the proposed model. The results also have indicated that the quality of IoT services (scalability, availability, reliability and ease of use), security of IoT services (trust, reputation, privacy and encryption) and IT knowledge of users (usage skills, awareness, experience and accuracy) have a positive and significant impact on development of e-business. Furthermore, the obtained results have revealed that the operating cost of IoT services (transmission time, storage capacity, functionality and stability) is significantly influenced by the development of e-business. Research limitations/implications By capturing a number of important factors in the proposed model, this study can provide a significant theoretical influence for researchers in the related area of interest. In fact, this study provides a worthwhile direction by assessing e-business performance, which, so far, has not been well assessed in many developing countries. Practical implications From a practical perspective, the statistical results support the crucial role of the following factors: quality of IoT services, the security of IoT services, operating cost of IoT services and IT knowledge of users. Hence, aspects relating to these factors must be the focus of attention of any organization in their endeavor to development of e-business. Originality/value This study meaningfully contributes to the knowledge and literature by focusing more on development e-business and IoT as original technology for further understanding, investigating other important features and applying advanced statistical analyses technique. By doing so, this study was able to develop the current understanding regarding the main aspects of development e-business and IoT services.
