I have to admit to not being up on the specifics of IBM’s current organizational model. I’m not a big fan of organizational structures that rely too heavily on matrix models, but as stated in the article, they can have value if used sparingly and properly. I’m a big fan of ownership of results–anything that detracts from that in a major way is a negative, imo. In general, though, results speak for themselves, and IBM has done well over the last decade or so. So maybe they’ve found a great balance. Whatever they’re doing must be working pretty well.
