The Outsourcing Model Redesign report suggests that companies should take a fresh look at their established outsourcing partnerships to unleash latent improvement potential. The report highlights that while outsourcing has achieved cost reduction and flexibility, many companies are reconsidering this approach due to dependency on outsourcing partners and difficulties in steering them. The report suggests several improvement levers and benefits, including increasing transparency on assets and in-sourcing key cost factors, optimizing maintenance processes, introducing incentive schemes for first and second-level support, standardizing third-level support contracts, reducing interfaces between partners, standardizing processes across all partners, building strong internal architecture management, reducing architecture complexity, and changing the operating model to increase efficiency.
