Once worked for P&W in the engine fuel controller division(nice on board computer, worth about 25% of the total cost of an engine). Management came from the propeller division (told you i was an old fart).
recall management demanding that i run a 1000 hr test in four weeks, no matter how much overtime it took.

Of course project planners should know this too, but they don't always use this knowledge in official plans.
However, a common scenario in software (where I have some professional experience) goes a bit like this:
Boss: Please give me a schedule estimate for this project.
Project manager (goes off and works on it, then): Twelve months.
Boss: That's too long. We need it in six.
PM (goes off again): Can't be done in less than ten.
Boss: Didn't you hear me? We need it in six.
PM: Ten is the minimum.
Boss: If you can't do it in six months, I'll find a project manager who can.
PM: OK, six.
The PM then updates his or her résumé, starts hunting for a job, and leaves before the fit hits the shan. The project, with a new manager, is finished (if the firm is lucky) in ten to twelve months.
The pressures in the aircraft biz are different, but how many 787s would Boeing have sold if they had said, from the get-go, that the first customer revenue flights wouldn't be until 2011 (or 2012)? The fact is that unrealistic schedules pay off in many ways for people who come up with them. They're not going to go away. As customers, we can only protect ourselves against it by not betting too much on any supplier making its promised schedule for a new, innovative product. It's OK to be the launch customer for something, at least you'll have it before anyone else does, but don't count on that happening anywhere near the original date.
Very well stated. This really is how it is. Our society rewards those that promise amazing results, and rarely punishes when they don't deliver. In the end, it was still better for them to keep pushing back the schedule than to give a date far, far away.
Damage to their reputation? Pfft. Big deal. What are the going to do, take their business elsewhere?

Yep, sure she is. I can't wait to see. I am looking forward it real soon. Boeing will continues in progress during pre-flight test will be done. When 787 will be ready to fly into the skies for first time.

Some other post also mentions that Airbus is not using composites over very large surfaces compared to the 787. Hopefully, this and experience in previous manufacturing delays on other Airbus a/c would mean "lessons learned" for the rollout and production of new a/c.

Amen....

That is correct and Airbus is using composites for quite some time now. Boeing has hardly any experience with this material for commercial airplanes - in comparison to Airbus. Airbus still considers it as too risky for production if the parts are too large.
And now sit down, lean back, switch your brain on and think about these structural problems Boeing is observing. That really scares me.
If I can choose, I will really think twice using this airplane in the first years of service.
The prestige object Dreamliner becomes for the aircraft manufacturer Boeing ever more the nightmare. With 23 machines of the new series 787 on the outer skin of the trunk folds were discovered, said a company spokeswoman on Friday. Therefore the production of new trunk parts in a plant of the Italian partner Alenia was stopped in June.
Thanks for the hint. One should really check all links before saving.
