For 20 years, Boeing has engaged in collaborative product development with a significant number of suppliers. The outsourced R&D, in turn, supported outsourced manufacturing with over 50 key suppliers. These suppliers, in turn, outsourced various parts of the modules they produced to their suppliers. Historically, Boeing was vertically integrated – the great majority of product development was done in-house. Boeing is now a case study in how not to outsource a supply chain.
Quality issues have recently bedeviled Boeing. On January 5th the mid exit door on the left side of the 737 Max 9 blew off at 16,000 feet during an Alaskan Airlines flight. Rapid decompression then resulted. It was a minor miracle that no one was sucked out of the plane. The flight did not have passengers next to the missing door, which was very unusual.
There have been other incidents. In 2018 and 2019 there were two fatal crashes of the 737 Max 8. These claimed a total of 346 lives and led to a 20-month grounding of the aircraft.
“The company aimed to develop the aircraft quickly and inexpensively to compete with the Airbus A380. Instead of developing the aircraft in-house and sourcing parts from suppliers,” Dr. Tang explained, “Boeing decided to outsource 70% of the design, engineering and manufacturing of entire modules to over 50 strategic partners.”
Advanced software is not a magic wand. “Boeing failed to establish the close supplier relationships that took Toyota decades of effort and commitment to develop. Without close communication and coordination among the partners, Boeing could not manage its external development process effectively,” according to Dr. Tang.
Recent investigations have revealed serious production control problems within Boeing’s supply chain operations. On January 30, Boeing indicated that the bolts required to fasten the fuselage panel of an Alaskan Airlines aircraft were missing when the plane left Boeing’s facility. This incident might be because of oversights in documentation and procedures at Boeing’s Renton factory in Washington.
But if Boeing can’t even manage processes in their factories, how good can they be at managing their partner’s manufacturing processes? A failure by Boeing supplier Spirit AeroSystems seems to confirm this suspicion. Spirit AeroSystems manufactures the fuselages of the 737 Max jets. They notified Boeing that two holes may not have been drilled exactly to Boeing’s specifications.
Airbus also uses advanced PLM software to co-design their planes and has also largely outsourced the production of key aircraft modules. But Airbus’s safety history in recent years is much better than Boeing’s.
In technology, it is commonly said that implementing technology is not enough. Companies need to pay attention to people, processes, and technology. There is growing certainty that Boeing is not paying enough attention to their internal and their partner’s quality culture and processes.
