Just-in-time delivery has made supply chains lean, but when a single port closure or chip shortage hits, we see empty shelves that could have been prevented with more buffer stock. Are lean supply chains still the right model, or is the cost of resilience worth paying? I've seen companies scramble for months after one disruption, and the hidden costs of downtime and lost sales must be weighed against holding inventory. In the post-pandemic world, maybe we should store more critical items locally, even if it means slightly higher costs. What's your take—should logistics prioritize efficiency over resilience, or is it time to rethink this tradeoff?
