Case Study: Express Scripts achieves millions in annual savings with Pegasystems

Express Scripts Driving ROI from the center of excellence, powered by Pega

Express Scripts, the largest pharmacy benefit manager in the U.S., needed to reduce silos across its Center of Excellence (COE) and manage 24 applications with a large developer team spread across two countries. Working with Pegasystems and its Pega platform, the company sought a way to unify disparate applications, improve governance, and increase ROI from its technology investments.

Pegasystems helped Express Scripts implement a common layer within the COE to consolidate applications, reusable components, and design patterns, while also building a stronger developer ecosystem through training, apprenticeships, and certification. The results included annual COE savings of $1.8M–$2.4M, a common layer supporting about 13 applications, 65+ rule sets, and 200 integrations, faster universal upgrades, and an 85% certification rate among developers in training.
