Frustrated, she grabbed her battered copy of Supply Chain Management by Sunil Chopra—the 7th Edition, the one with the green cover that looked like it had been through a war. She flipped to Chapter 14, "Transportation in a Supply Chain."

And that is how a 47-page PowerPoint, built in a panic at midnight, saved a $200 million supply chain.

"Maya, don't trust the PPT from corporate. The inventory turnover ratio they sent is a lie. Use the 7th Edition formula on page 412—the one about cycle inventory. I've attached the real warehouse data."

She froze. Page 412 was the chapter on "Managing Economies of Scale in a Supply Chain." She opened her laptop and searched for the unofficial "Sunil Chopra 7th Edition PPT" that a classmate had shared in a Google Drive years ago. It was a messy, pirated slide deck full of typos, but Slide 34 had a diagram she needed: the infamous "Risk Pooling" graph.

She had inherited a mess. Three regional distribution centers were operating at 140% capacity, a key supplier in Vietnam had just been hit by a typhoon, and the CEO kept demanding "Amazon-level speed" with "bargain-bin inventory costs." Her theoretical knowledge felt useless.

The Last Slide

At 8:00 AM, she walked into the boardroom. The CEO frowned at the lack of flashy graphics. But as Maya walked through Chopra’s framework—network design, transportation modes, demand uncertainty—the CFO leaned forward. The COO stopped checking his email.

"The drivers of supply chain performance," she whispered, tracing the margin notes she’d made in grad school.

Maya smiled. "According to Chapter 7 of the 7th Edition? Ninety days. If you approve the cross-docking strategy on Slide 42."

She quoted Sunil Chopra directly: "The key to supply chain success is not minimizing cost, but maximizing surplus."

When she clicked the last slide, the CEO asked one question: "How fast can you implement this?"

She closed her laptop. The stolen PPT had given her a template. But Sunil Chopra’s principles had given her a backbone.

She realized her predecessor had built three separate, expensive warehouses to serve three customer segments independently. That was why capacity was bursting. Chopra’s book argued that aggregating inventory into two strategic locations would reduce the standard deviation of demand by 35%.

With renewed energy, she began deleting slides. She replaced the complex ERP screenshots with a single, simple diagram from Chopra’s PPT template: Cycle Inventory vs. Safety Inventory.
