case study

Political instabilities, technology advancements, changing customer tastes, globalization, and cultural changes are among the factors constantly forcing telecommunication organizations to change. Thus, change is certain in telecommunication organizations nowadays. Managers in this departments realize the significance of change management in the change process. This is shown and published in numerous studies. However, there seems to be lack of managerial structures that help telecommunication companies implement effective change management practices. This paper presents a managerial framework for the implementation of change management in telecommunication departments. The framework is constructed using empirical findings from one case study of East Azerbaijan telecommunication companies. It consists of four main dimensions, namely change planning, change management, change reinforcement, and change feedback collection. The value of this framework is that it represents an initial attempt to explore factors of successful change management in telecommunication departments. The paper concludes with research and practice applications of the managerial framework.

As projects increase in size and complexity, they become more difficult to handle. One of these large and complex projects is oil and gas projects. The current controlling processes of projects are not able to detect the problems in early phases of the project and are rather late leading to extra time and cost. One solution is to find symptoms of problems in the early phases. Due to the importance of drilling projects in upstream sector, the main objective of this research is to identify the early warning symptoms of problems in drilling projects and to find the relationships between selected early warnings with project outcomes and problems of these projects. To reach that aim, the early warnings have been recognized through literature review and interviews with experts. Then, case study analysis is performed to find the relationships between early warnings and project outcomes. All cases have been selected from previous completed drilling projects in one of the oil fields of Iran. Findings show that there is a relationship between early warnings, project outcomes and projects problems.

Purpose: In this study, a minimal theoretical framework was set based on the coexistence of different analytical levels to discover the causes for the success of students and schools in science Olympiads with two separate analysis units. Methodology: This research has been conducted at two micro and intermediate levels through multiple case study and in-depth interview. At the intermediate level, the analysis unit was school and the statistical population included all schools. The intermediate level research sample included two sets: positive cases (5 successful schools from Yazd province) and negative cases (5 unsuccessful schools from Ardabil province), which were selected purposefully. The strategy used at this level was multiple case studies, and the results were analyzed with the comparative qualitative technique. For the validity and reliability of the measuring instrument at this level, real and theoretical repetition was used. At the micro level, the unit of analysis was Olympiad students and 10 interviews were conducted by considering the condition of theoretical saturation. The research tool included in-depth interviews with students, which were analyzed using the grounded theory and the open-centered-selective coding technique. For the validity and reliability of the measuring instrument, the inter-coder agreement and the review of the results by the members were used, and in the comparative study, real and theoretical repetition was used. Findings: This study showed that students’ success in scientific Olympiads is a function of the constructive interaction of the two main institutions (school Olympiad atmosphere and attracting family support) and regional success experience. Other factors such as student cognitive interest, the attractiveness of Olympiad competition, and external incentives are also important. The results of comparative analysis of schools are parallel to the results of the above research and complement it, as the results showed that among the successful schools, almost all the main criteria, including the seminar to introduce parents to attract their support, educational counseling, and classes by former medalists, among other factors, determine the success of schools. Conclusion: According to the findings, it should be said that the success of students and schools in the science Olympiad is affected by several factors at the micro, intermediate, and macro levels, including the quality of the actors to the synergistic atmosphere of school and family.
