In the established world of UK financial services, creating the O2 Wallet by Telefónica — a telecommunications company — was a bold, innovative and complex undertaking. Realising the concept of “putting your wallet on your mobile phone” involved the integration of multiple parties and vendors, technologies and operating models — and all at different stages of maturity. Faced with this challenge, Telefónica approached Navigant in order to leverage expertise in financial services and the telecommunications markets. Navigant helped to structure the complex change programme, reviewing contracts, assessing application security, and aligning the interests and deliverables of all contributing parties. The result was a focus on key activities in the build up to launch, and on 26th April 2012 the Telefónica team launched the O2 Wallet into the UK market.
