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.

This study tries to investigate the barriers to the development of shared businesses in Tehran. The research method in this study is qualitative and the data collection tool is a semi-structured interview. The informed statistical population includes 30 university lecturers, elites, graduates, entrepreneurs and manufacturers. The subjects of the recorded interviews were extracted by the lecturers of the Business Management Department and analyzed using the network themes method in MAXQDA software. Findings show that 64 barriers have been identified as the basic themes and after reviewing the opinions of experts, these barriers have been classified into 6 main themes. These barriers are: trust barriers, technology barriers, knowledge and information barriers, economic barriers, political barriers and managerial barriers.
