Boeing miswiring 787 and Airbus350

: Boeing787 and production miswiring from 2011 - 12 then, fire on battery
Boeing was, in the past, farmous for the 737 & 777, but things started to go wrong in 1995 with a change from technology based working to marketing based approach, and it is surely this which lies at the heart of its endless problems with the 787(seven late seven), starting with the "stuck together" launch and the repeated delays to the schedule.
the events of Set-11th caused a sharp drop in orders to which they responded by increased marketing pressure.
It appears theat someone in the company, surely in marketing rather than on the technical side, thought aircraft could be built on the same sort of assembly line system that is already used for car manufacture, without apparently taking into account the vastly greater complexity or the problems of introducing new and untried technology and design at the same time as trying to introduce a whole new working and assembley system with worldwide (45 campanies) ramifications.
---In 2007,the company announced that 112 787-plaines would be producted
per year. They set up a derivery schedule to the various air-lines.

With hindsight it is hard to understand why Boeing failed to forsee that massive problems were probably inevitable under these conditions, but they
are certainly suffering financially for their mistakes.
Then Alan Mulally, the head of the 737 and 777 programs, left in 2006.

But when Boeing reshuffled its top management , Oct 2009 ,--
three years after Mr Mulally let - the world's second-largest aircraft manufacturer signalled renewed commitment to engineering and execution over glossy marketing.

Jim Albaugh, the former head of the campany's defence divison, as head of the commercial arm. His appointment is meant to put a stop to the damage the mismanagement of the 787 and 787-8 has wreaked on the company's reputation and bottom line.

No doubt they will be more cautions in future.

Then, the company had a big mistake,    
Wiring miss,  which has been discovered by Japan Air Line.
JAL 's 787 have had fire on Jan. 2012 in USA twice, and All Nippon Air had two same problem  in Japan, the emergency landing had been happen in Matuyama-airport, then the pilot switched off all power before leave the 787, but a light of wing-let was still stwich on.

then, JAL discovered that the wiring to wing-light system had wrong, and report to Boeing on mid of Feb in 2012.
But the company did not reply, and egnore  the JAL report.
As the Boeing said the fire problem coused by battery falt, they will not accept any mistake at all.

JAL, used to state air line company and mainly orderd Boeing as Japan close to American government,
hoowever, the report was ignored by Boeing means some mistake would be happened again in future,
JAL has decided to change the order to Air-bus company rather than Boeing.
JAL never trust Boeing production any more as the latest model 787 have had miss-production, and nevre accepted  any suggestions even it is real problem.

The company's trust has been running out, never accept any comments or improvement at all.

New 737,    737-max will be produced with a large order-number(more than 1000) ,  this kind of porblem(miss-wiring  =  fire the battery)  would lay on production line again.

They never think about custom problem or consider any schedule flight problem when airlines use new Boeing
