"...<suppliers> are now committed to making that design work and delivering it on the original schedule."
...and how do we define "making the design work"? Well, the engineers will tell you that. Except, the engineers who were to tell you that assumed you know how Boeing does things, all those little details that are in the cracks of the assembly hangars and scribbled in the margins of the design manuals...oh, and most of those Boeing engineers have been re-assigned and won't be available to take your calls as they're busy elsewhere, putting out somebody else's fires.
Biz as usual. That the Big B is not further behind on the 787 is testimony to a very diligent effort at keeping open lines of communication with their suppliers, using new collaboration tools, electronic file sharing, etc.
