Grand Theory

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. In the open coding phase, the data was 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 studied, providing a common model for all three companies and also providing a common model for all three companies.

A strong brand differentiates the product from competitors' products, reduces search costs, minimizes perceived risks, and offers high quality from the customer's point of view. He considered that one of the most important problems of Iran's food industry is related to the brand name, especially in the field related to the internalization of awareness and association of the brand name in the customer's mind. Cognitive distortions, as psychological factors that cause perceptual errors in people, can be effective in their negative feelings and, as a result, affect the expected results of customers' behavior; Therefore, identifying the psychological components of branding in the food industry with the foundation's data approach (case study: Gaz Asari) is of great importance. The method of this research is qualitative and grounded theory method (foundation data) which has been used in this research due to some of its special features. The statistical population consists of interviews with 17 people, including all managers and expert managers in the Gaz Asari brand industry, which means analyzing the data obtained from the interviews, using the qualitative-inductive grounded theory method (including the steps of open coding, central coding, and selective coding). The results include 19 general categories in the form of a paradigm model, which include causal conditions (competitive pressure, changing customer characteristics, market uncertainty, understanding the importance of branding and lifestyle changes), central phenomenon (psychological branding), background conditions (sustainability of brand effects) flexible characteristics of the brand and branding skills, intervening conditions (customer, company capability, brand competition capacity and the challenges of Sanat Gaz administration) and strategies (differentiation strategy, modeling strategy, discovery strategy, and resistance strategy) and consequences (short consequences duration and long-term consequences).
