Bombardier is poorly managed company. With end of corporate welfare by Federal government it's very difficult for Bombardier to survive.
Due to poor planning and incapable management the production costs are too high.
In my estimate the labour costs to assemble a Global 7500 aircraft is same as A380.
Bombardier employees cannot do it right first time. Parts / assemblies are installed , removed, reinstalled on air crafts because workers lack the required skills.
