I worked in the Product Development department as an Assistant Merchandiser, where I witnessed the vertically integrated "Fiber-to-Fashion" operation. The study focuses on applying PGD-KIM curriculum competencies in a real-world composite production scenario, such as Industrial Engineering (KIM 202), HR Skills (KIM 101), and Quality Management (KIM 204). Important findings include how lead-time management affects manufacturing effectiveness and how 3D virtual prototyping might revolutionize the process. The evaluation emphasizes how Interstoff uses technology to uphold its "Zero-Defect" ethos. The paper ends with strategic recommendations for both personal and professional growth goals aimed at attaining entire factory management proficiency and industrial improvement, including predictive lead-time analytics.46 pagesen-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalBRAC University internship reports are protected by copyright.
