The article shows the necessity and timeliness of building trusting relationships between stakeholders in projects to create a dairy cluster - an association of institutionally independent enterprises integrated into an inter-industry complex, in order to obtain a synergetic result from balanced cooperative relations between them. The cluster should take into account the interests of all its participants, so maintaining trust between them is necessary for the formation of the food chain in the dairy business, which in turn serves as a catalyst for the effective development of the dairy industry, increasing the volume of production and quality of dairy products. The aim is to study the influence of factors on the common interest, partnership between stakeholders in the project environment, as well as the development of methodological and practical recommendations for the application of tools of effective interaction between them, which contributes to the success of the project and the achievement of common goals. Methods - abstract-logical to identify problems and causes, online survey of respondents using Google-form, Cronbach's Alpha modeling methods are used to assess the reliability and internal consistency of questions in the model created in the Smart PLS program when analyzing complex relationships between latent variables (constructs) that cannot be measured directly. In the course of the study 76 respondents from all regions of Kazakhstan, which are potential stakeholders in the activities of the dairy subcomplex, were interviewed. Results - reliability and validity of the chosen conceptual model were established, the necessity of deepening the hypotheses put forward during the life cycle of the project on the functioning of the dairy cluster was proved. Conclusions - innovative entrepreneurship cannot be successful without managing the process of forming an atmosphere of trusting relations along the entire chain of the production process - from investors to consumers.
