401: Express Scripts CTO emeritus Phil Finucane details Express Scripts’ integration with Cigna. While Cigna has a strong engineering organization, the two companies have different visions for how to execute a successful integration. Because of this, a large part of Phil’s job was to help Cigna understand how Express Scripts operated, to understand how Cigna operated, and to understand how the combined entity would interface with its business partners. From there, Phil looked to build a path that brought together the best of both worlds by bringing complementary strengths together. We also discuss the lessons Phil has pulled from his time in Silicon Valley, Express Scripts’ approach to eliminating technical debt, his take on artificial intelligence, and a variety of other topics.
