The geopolitical landscape is contingent upon the comprehensive strategic choices made by global leaders representing the United States, Russia, Turkey, India, the European Union, and Middle Eastern countries. There are several attempts made by researchers and industry practitioners to appropriately synchronize the demand and supply during this disruption. Substantial research has been conducted and literature is available in the field of supply chain collaboration. However, collaboration can’t be ensured unless the end-to-end SCM is synchronized through the Sales & Operations (S&OP) planning. Achieving smooth collaboration poses a formidable challenge, particularly amid disruptions and volatile conditions as seen today. This study undertakes a comprehensive examination by conducting a systematic literature review on various facets of sales and operations planning (S&OP), coupled with a survey utilizing a self-administered questionnaire across 24 manufacturing industries in Bangladesh. The primary aim of this paper is to assess S&OP best practices by evaluating different aspects applied in the industry, to ensure seamless connectivity, collaboration, and establishing criteria for
