Every company should think about producing new goods, the production of alternative goods is necessary in order to stabilize the level of sales or new sales; Customers also want new products, and if the company neglects to do so, competitors will certainly do so. Therefore, the present article seeks to provide a model appropriate to the conditions of gas refining companies for product development. In this study, the qualitative research method has been used as a grand theory; Using theoretical sampling and theoretical saturation, 20 experts of gas refining companies (Parsian, South Pars, Fajr Jam) were interviewed. Based on the basic theory, the data were analyzed in three stages of coding (open, axial and selective) using MAXQDA software. In the open coding phase, the data were labeled conceptually and then those that were common to each other were named into a category; the obtained categories were 43 categories. In the central coding stage, logical relationships were found between the categories and the obtained categories were included in the open coding under more general categories; finally, in the selective coding stage, all categories were summarized in one main category. The main category of the research was named "Interfering factors in new product development". The final result of this research, according to the researcher's attention and reflection on the details of the process of each of the three refining companies, is to provide an existing common model for all three companies and also to provide a common desired model for all three companies.

Insurance Corporate Governance Code 93 was communicated to the insurance industry of Iran in 2017. However, as the only Iranian governmental insurance organization, Iran Insurance Company has a different corporate governance structure in the insurance industry of Iran. The present study aims to propose a good corporate governance model at Iran Insurance Company. This study is applied research in terms of objectives and descriptive-survey research based on a combined methodology in terms of data collection. Semi-structured interviews were performed with fifteen experts. The final model was proposed through thematic analysis and the Delphi model with five components, including board effectiveness, transparency and disclosure, ownership institution, beneficiary management, and monitoring. The model was examined by delivering questionnaires to a total of 201 senior and middle-level managers and agency directors at Iran Insurance Company. The Kolmogorov–Smirnov test was utilized to determine data distribution, while the Kaiser-Meyer-Olkin (KMO) test and Bartlett’s test were used to examine measurement sample suitability. Also, the partial least square (PLS) method was employed for modeling in Smart PLS. The components were ranked through the Shannon entropy approach. The results demonstrated that board effectiveness had the largest importance among other components. The board structure and composition showed the highest weight. Among the components of board effectiveness, the separation of the chairman and CEO had the highest importance.

Building Information Modeling (BIM) is the backbone of the Architecture, Engineering, and Construction (AEC) industry. BIM is the collection of Information and Communication Technologies (ICT), interacting policies, and procedures. BIM generates a methodology to manage the project data in digital format throughout the building's life-cycle. Despite the numerous benefits and features of BIM, its proliferation remains limited and facing adoption issues. Although many existing studies discussed BIM adoption from contextual lenses, discipline-focused, there is still a scarcity of a comprehensive overview of technology adoption models and frameworks in BIM research. The purpose of this Systemic Literature Review (SLR) is to evaluate the current status of BIM adoption, technology acceptance theories, models used and find the research challenges. Furthermore, to identify the roles of independent constructs, dependent construct, moderators, and mediators in BIM adoption research. Also, the findings provide an in-depth description of the different stages of BIM adoption. Finally, this SLR will help the researchers for further research in the field of BIM adoption.
