Tivoli is a leader in software for systems and storage management, security, storage and business systems management. Acquired by IBM in 1996, Tivoli became the systems management brand of the IBM Software Group. IBM allowed it to operate as a wholly owned subsidiary for a few years before forming the Software Group. In addition to Tivoli this IBM division includes WebSphere, Information Management, Lotus Software and Rational Software. In August 2006, IBM acquired MRO Software, intending to add them to the Tivoli division.
