One of the global leading banks created about 30 platforms. One such platform was payments, which consisted of more than 60 applications that previously had been managed independently from each other. The top team decided to bring the 300-plus IT people working on development and maintenance of payments together with the corresponding people on the business side. Under joint business/IT leadership, this entity was empowered to move quickly on priority business initiatives, to modernize the IT structure, and to allocate the resources to make that happen.
The team shifted its working model and started running the payments platform as an internal business that served all the different parts of the bank (think payments as a service). This approach made it clear where to focus specific tech interventions: removal of nonstrategic IT applications; modernization and accelerated shift of the target applications into the cloud; connectivity to enable swapping solutions in or out easily; and, most important, a major step-up in feature/solution development for the internal business clients. This platform-based way of running the business was then progressively rolled out across the group. Prioritization is set by the top team (because empowerment does not mean anarchy), and all IT interventions are run the same way, to ensure consistency and replicability.
Their notion of a platform is more like the old API economy thing:
A platform-based company will have 20 to 40 platforms, each big enough to provide an important and discrete service but small enough to be manageable. To simplify platform management, it helps to group them into three broad areas: customer journeys, business capabilities, and core IT capabilities (Exhibit 1).
For example, in personal banking, the customer-journey platforms cover the customer experiences of searching, opening an account, getting a mortgage, and so on. The business-capability platforms deliver the banking solutions, such as payments and credit analytics, and the support capabilities, such as employee-pension management, visual dashboarding, and management information systems (MIS). Finally, the core IT platforms provide the shared technology on which the journeys and business capabilities run, such as the cloud platform, the data analytics environment, and the set of IT connectivity solutions.
