Rob,

If your focus is integration, then you're less likely to be thinking
about reducing redundancy through application consolidation.
Integration is driven by individual projects, i.e., taking lots of
small steps, but not bothering with the "thinking big" aspect. If you
combine SOI with. Strong application portfolio management effort, then
I don't think the difference is anything to be concerned about. The
execution of specific projects tends to be equivalent.
