I blame changing requirements. I've yet to see a large project which hasn't changed its requirements along the way. On the other hand airplanes are designed tested in small scale for proof of concept and specs are finalised before any production work begins.
- static_noise 9y agoNow that you say it, I believe that there are several (military) aircraft projects that have huge delays exactly due to changing specifications. The people making the contracts did not have a clear vision about what they actually want and there are several parties involved who want different things crammed into one vehicle. As the process moves on, the requirements get adjusted to meet the new political power balance. The commerical planes, I believe, were designed with a clear goal and are in many ways an incremental improvement on the previous (proven to work well) models. So in essence you need: A clear vision of something that is acutally achievable. Plus you need to communicate that vision.

- kyriakos 9y agoThis actually proves my point that having a solid spec also means a quicker project completion.
- lightedman 9y agoThe spec was solid - superior LAS capability over F-22 and F-16 and F-14. How to get that spec realized, well...
- Too 9y agoWriting a solid spec isn't free either. You spend 5 years on writing a spec and 1 year implementing, instead of the other way around.
