"The team has followed a disciplined process to complete all of the requirements for this stage of the programme," says Bob Feldmann, Boeing's general manager for the 777X programme, which also includes the longer-range 777-8X variant. An internal restructuring at Boeing's commercial division in 2012 created a consolidated Airplane Development organisation, a move intended to ward off the delays that plagued the 787-8 and 747-8 programmes. With the possible exception of the KC-46 programme, which includes development staff from the commercial and military divisions, the new structure has kept Boeing's commercial projects on time. The 777-9X appears to be continuing the trend, with firm configuration completed on the originally scheduled date set two years ago. Until now, Boeing has focused development on validating the aircraft's basic performance against a set of requirements.
