A traditional bank can launch a digital bank via two approaches – using a brownfield approach or a greenfield approach. The brownfield approach remains the oldest form of digital transformation and still resonates with bank leaders worldwide. However, deploying a complete big-bang strategy can be time and cost-intensive. Moreover, legacy infrastructure enhancements and upgrades can be complex activities. Banks such as Goldman Sachs, HSBC, DBS, and others have taken a new approach, known as the Greenfield approach to building a digital bank to overcome these roadblocks and challenges. By definition, Greenfield allows the incumbents to break free from existing systems, business models, and talent constraints.
