Smart digital tracking in lean supply chain: a process model and aerospace case study

This paper investigates a process model for implementing Smart Digital Tracking within a supply chain (SC) aligned with Lean strategy. The Lean approach emphasizes value creation by focusing efforts on the implementation of Smart Digital Tracking. The study identifies critical criteria for selecting an appropriate Proof of Concept (PoC) and a suitable customer for initial implementation, setting the foundation for scaling the digital tracking system across a broader product portfolio and customer base within the SC. In addition to highlighting the strategic significance of digitalisation as the future of SC management, this study provides a Process Implementation Model to guide decision-makers in adoption digital tracking systems. The proposed methodology, inspired by kaizen, incorporates an advanced PDCA cycle designed for Lean 4.0 projects, with a focus on integrating simulation capabilities during the implementation of new digital solutions. The paper concludes with a case study from the aerospace industry, showcasing a company's efforts to implement a digital tracking solution while simulating various scenarios. The study addresses the company's challenge of selecting the optimal PoC and determining the most appropriate customer for the initial deployment. Furthermore, the proposed framework fosters and open collaboration by enabling the testing of various delivery reconfigurations supported with Digital Tracking.
