Given that AT&T would now be a focused telecommunications service provider, it made sense to expand the divestiture of AT&T Technologies into a "trivestiture" that spun off GIS, now renamed NCR, along with Lucent Technologies.
The failed AT&T computer venture was an indicator of what needed to be fixed within Lucent immediately after the "trivestiture." Speed in decision-making and execution of plans was an imperative, and risk taking needed to be tolerated and rewarded.
Prior to the spin-off of Lucent as an independent company, the units forming Lucent operated within a competitive environment from the time of the AT&T breakup in 1984 until the "trivestiture" in 1995.
