Forrester's research on banking IT in 2023 identified a series of requirements and the architectural layers of the future banking platform. The key layers show: (1) a focus on personalized customer services and real-time information analysis; (2) a separation of product design and customization; and (3) a clear distinction between core competencies and nondifferentiation functions supported by selective sourcing. These layers will belong to one, two, or more financial services firms, and they will be connected via a federated semantic banking backbone. The outside world will use the services of these layers via the ubiquitous banking layer — also know as the evolution of the multichannel layer.
