The study undertakes a systematic literature review of government-provided E-Services for businesses (Government to Business E-Services). The literature review process selects and analyses 331 publications. The research highlights the polydispersity of identified publications, resulting from the fragmentation of disciplines. The primary activities in this research field occur mainly in Europe and Asia. In addition, there is a steady engagement of researchers on G2B E-Services. The overall maturity level of governmental services identified in the literature review is quite satisfactory. The main research topics are E-Procurement, E-Customs, E-Taxes, Interoperability, Process Transformation, Cost and Pricing Issues, Barriers and Key Success Factors, and Assessment of Effectiveness. Case studies and surveys are the most popular research methods. In the future, a deeper analysis of the stakeholders' views, enhancement of planning, development and transformation of G2B E-Services, redesign of back-office processes, and interoperability between different systems should attract research interest. Finally, we expect further analysis of E-Customs and E-Invoices, as these services have significant added value.

The Natural Gas Distribution sector is considered one of the most critical areas in which Industry 4.0 methodologies can be applied, as they form a part of critical infrastructure management where automation, information technology and high-tech solutions can offer high-level service. The paper aims to identify critical business processes that can substantially benefit from Industry 4.0 and Information Technology solutions in a Natural Gas Distribution Company which distributes Natural gas in Greece in Medium and Low Pressure. The research conducted identified the company’s business processes and highlighted these which are critical to its operation. Having identified the technological advancements in the Gas sector, the business processes that can benefit from Industry 4.0 and Information and Communication Technologies were recognized. The results revealed three critical business processes that can be radically improved: management of new customers’ connections, project management of works projects and network maintenance. Technological approaches that can transform these processes were identified to be a real-time collaborative CRM system, a real-time collaborative project management system integrated with an appropriate document management system, smart meters, sensors and actuators for real-time monitoring of important operational variables and a monitoring system which collects and generates consolidated information in a Control Room. Identification of the processes into which Industry 4.0 and information technologies can lead to the introduction of corresponding solutions, can increase operational efficiency of company’s network and minimise running costs. The research effort should be continued in order to achieve higher integration between business processes, Industry 4.0 concepts and Information Systems.

This paper presents an application of multicriteria analysis in a large Greek company for the selection of an ERP (Enterprise Resource Planning) system. The limited time available in most of the companies for software selection, the inability to make fast but sound decisions on IT issues and the luck of technical expertise in ERP functionality often results in an undocumented or even irrational final decision. As a consequence, the purchase of expensive software ends up to be affected by issues such as personal acquaintances, sporadic information, fashion or intuition. Taking into account all the existing practical constraints in the Greek industry due to the limited existence of resources, a practical and easy-to-use methodological approach was developed, using the typical principles of multicriteria analysis for the software selection and implementer selection process. The objective of the approach is to provide an easy way to support the final decision in the selection problem in a documented manner. The practical application of the proposed approach is presented in a real case study of a Greek company, emphasising on the process, organisational and computational dimensions of the selection.
