Designing a Lean Integrated Management Model for Sustainable Development with Emphasis on the Environmental Dimension (Case Study: Medium and Large Manufacturing Industries of Qazvin Province)

The present study aims to formulate and apply a paradigm model of integrated management promotion with an emphasis on sustainable development. The research method is mixed, utilizing an exploratory approach (qualitative-quantitative). The statistical population in the qualitative part included 28 professors and elites in the field of management, while the quantitative part involved 480 craftsmen from Qazvin province. In the qualitative part, in-depth interviews were conducted with 20 experts using the snowball method until theoretical saturation was reached. In the quantitative part, a researcher-made questionnaire was distributed among 300 samples using a relative cluster sampling method to measure the model. The validity of the questionnaire was confirmed by face, and content methods and its reliability was confirmed by Cronbach's alpha method. Data were analyzed using exploratory and confirmatory factor analysis with SPSS and AMOS software.
