The statement I quoted is false, so I stand by my criticism
I see this statement as correct which is why I said you had misunderstood the HBR article. (as it happens I see several other posters since share my view).
The explanation of your misunderstanding is that when there is no outsourcing an aircraft company design office has many different specialist teams that are by definition already integrated in the one design office. If on the other hand specialist tasks are outsourced to one or more organistations you have to set up another home team to specifically integrate their efforts with those at home.
It is a pity you give no evidence of your education, training or experience which would help people respond to many of your seemingly incorrect notions around various PPRuNe threads. Of course you could also be a wind up merchant. We have no way of knowing.
