Our European client, a successful, international operating bank was experiencing far-reaching changes in its global financial markets business, both internally and externally. Together with the bank's international representatives, we designed a global target operating model that resulted in a long term, strategic system architecture. We started with a detailed analysis of the existing situation before defining the target operating model. In addition to information gathering and analysis of products, processes and systems, we looked closely at the roles of traders, risk managers, operations managers and finance representatives.
