Boeing outsourced 70% of the 787 Dreamliner — and lost control of its own airplane

When Boeing designed the 787 Dreamliner, it made a radical decision: outsource roughly 70% of the aircraft's design and manufacturing to a global network of suppliers. Partners in Japan, Italy, South Korea and elsewhere would build major sections, and Boeing would do final assembly. The goal was to cut costs, share risk and accelerate development.

The result was the opposite. Suppliers struggled with coordination, quality varied, and sections arrived at Boeing's Everett factory with missing parts and misaligned fittings. The 787 was delivered over three years late, with cost overruns estimated at $32 billion. Boeing had to send engineers to supplier sites worldwide to fix problems that should have been caught earlier.

The 787 eventually became a commercial success, but the outsourcing model damaged Boeing's engineering culture and institutional knowledge. The case is now cited alongside the 737 MAX crisis as evidence that Boeing's shift from an engineering company to a financial company — optimizing for cost and shareholder returns over technical mastery — had systemic consequences.
