Cost-optimized and resilient are different targets
Most supply chain networks in place today were built by a decade of relentless cost optimization: single-sourcing where a second supplier seemed redundant, lean inventory where a buffer seemed wasteful, concentrated geography where consolidation looked efficient. Every one of those decisions was individually rational against a cost objective, and collectively they built a network with almost no slack to absorb a disruption.
Resilience and cost aren't opposed in every case, but at the margin, they trade off directly: the incremental dollar spent on a second qualified supplier, a safety stock buffer, or geographic diversification is a dollar not spent on the lowest unit cost available. Most networks never made that trade-off an explicit decision. It happened by default, in favor of cost, because nothing was forcing the alternative into the conversation.
Visibility without a response plan is just faster bad news
A lot of the investment in supply chain resilience over the past several years has gone into visibility: better tracking, better data, faster alerts when a shipment is delayed or a supplier is at risk. Visibility is necessary, but it's frequently mistaken for the solution itself, when it's actually just the precondition for one.
Knowing about a disruption twelve hours earlier only helps if there's a pre-built response ready to execute in that window, an alternate supplier, a reallocation plan, a substitution rule. Without that, better visibility just means the organization finds out about the same problem sooner and still has to improvise the same response from scratch.
A supply chain optimized purely for cost is, by construction, optimized against resilience. Most networks never made that trade-off an explicit decision.

Where to actually build redundancy
Building redundancy evenly across an entire supply network is prohibitively expensive and usually unnecessary, because not every node carries equal consequence if it fails. The right approach starts by identifying which specific nodes, a single supplier, a single port, a single facility, would actually stop the business if they went down, versus which ones would cause inconvenience but not a real interruption.
Redundancy investment belongs concentrated on that first, much smaller list. A single-sourced component that's easily substituted doesn't need a second supplier. A single-sourced component with no substitute and a six-month lead time to qualify an alternative is exactly where the cost of redundancy is worth paying before the disruption forces the decision.
What resilient actually looks like in practice
A resilient supply chain isn't one with no single points of failure anywhere, that standard is unaffordable and unnecessary. It's one where the specific points of failure that would actually stop the business have been identified deliberately, and where a pre-built response exists and has been tested before it's needed, not improvised during the disruption itself.
Getting there requires treating resilience as its own explicit design objective, with its own budget and its own trade-offs made visible, rather than treating it as a byproduct that shows up automatically once cost optimization is done well. It doesn't. The two have to be balanced on purpose.
