Ah, ok. Your clarification on software for version tracking makes a lot of sense and I completely agree.
The software management issue I was talking about was a different animal. Take the Ariane V; the idea was the could iterate faster if they leveraged software reuse. Since it was previously verified software, they didn't think it needed much testing. But the new rocket design exceeded the assumptions in the previous iteration and the vehicle was lost. There's a lot of instances where software allows you to iterate faster, but you have to very careful about the baked in assumptions.
