The report "Manage IT as a competitive weapon" highlights the importance of rethinking IT investments as a competitive advantage rather than a cost. The authors argue that IT investments are often not fully understood and not assessed in the same level of detail as the corresponding IT expenditures. This results in significant imbalances between IT spend and Return. The report provides best practices for managing a solution portfolio and applying the right financial models in the right context. The authors are Olaf Tellefsen, Director of the PD and PLM group at the Volvo Group, and Anders Johansson, Partner and Head of the Global Technology and Innovation Management Practice at Arthur D. Little.
