In this week's Mini-Simulation, I decided to opt for multiple backup vendors for the catheter coating material, despite the added time and cost implications of validating and verifying each vendor's product. My decision was primarily driven by the need to ensure a consistent supply chain and to mitigate risks associated with relying on a single source. Having multiple vendors can be a safeguard against potential disruptions, such as material shortages or vendor-specific issues, which could jeopardize the whole project. The initial increase in cost and time seemed a worthwhile investment to protect the project's long-term viability and maintain quality standards across the board. This approach also aligns with a broader strategy of risk management and sustainability in supply chain logistics.
