The space shuttle’s design was also deeply flawed to the point it failed to do the core objective, significantly lowering costs. Instead the core mission was sacrificed to meet some arbitrary design goals such as being able to de-orbit heavy objects. That’s the core issue with decomposition of tasks, you aren’t communicating back up the chain and finding globally optimal solutions unless the task is simple enough to be completely understood.
