The rework decrease through 2025 is “incredible and very significant,” Ihssane Mounir, senior vice president of Global Supply Chain and Fabrication for Boeing Commercial Airplanes (BCA), told supplier partners, speaking Feb. 11 at the annual Pacific Northwest Aerospace Alliance (PNAA) conference in suburban Seattle.
“When you think about how that happened, it’s a whole slew of things that had to happen to drive the number down that way,” Mounir said in a talk that touted Boeing’s recovery to its supplier partners after six years of crisis and production problems.
Mounir assumed the role of SVP, Supply Chain and Fabrication, in December 2022, following six years as BCA’s top sales executive.
“It’s you paying attention to quality. It’s us augmenting our quality in our engineering teams, our fabrication teams, and our support teams, and putting them with you and helping you,” he said. “It’s us increasing our engineering support and being more responsive to the changes and to the asks and the analyses that come our way.”
The prevalence of supply-chain defects and Boeing’s need to rework incoming parts and subassemblies during production had become a source of deep conflict between the company and many of its 1,200 suppliers for several years.
