When Process Optimization Creates Brittle Systems: What to Fix First
Here is a scene from a warehouse in Memphis, 2019. A crew had trimmed every second from their picking route—aisle sequencing, handoff timing, even the angle of label scanning. They were heroes. Then flu season hit. Two people called in sick. The entire setup seized. No one had cross-trained for the third zone. The optimised route assumed full staffing. It took three days to recover throughput. The staff didn't celebrate their efficiency anymore—they stared at the flowchart and asked what do we fix primary? This article is for anyone who has ever watched a beautifully optimised approach snap under a mild disturbance. We will walk through why brittleness happens, what patterns keep systems resilient, and—most importantly—how to decide which repair to tackle initial when everything seems fragile. No buzzwords. No guarantee of perfect agility. Just a practical framework for audits that do not trade flexibility for speed.
