This document discusses how banks, fund managers, and software vendors can transform their IT estates to deliver significant financial and environmental benefits. It provides an example of a large UK employer that achieved savings of £2.9 million over 6 years through IT transformation, including increased availability, performance, and reliability as well as reducing their audited carbon emissions by 39,998 tonnes per year. The principles behind a successful transformation include leveraging common requirements through shared IT environments and standardization.
