Build better customer-centric apps with Pega's BPM platform. Use visual tools to quickly build an executable model of the enterprise application that your business requires, then elaborate on the details in a unified model-driven platform. Communicate with legacy systems using configurable connectors (e.g. SAP, Salesforce), open, standards-based protocols (like SOAP, REST), and the open Pega API. You can also embed Pega in your existing apps through Pega Mashup. Standardize business processes across your global enterprise while providing for governed variations to optimize your business applications in each business unit, geography, and legal jurisdiction. It helps you quickly build business applications that deliver the outcomes and end-to-end experiences your customers demand. Pega enables business stakeholders to accelerate enterprise app development through visual tools (no coding), support for business/IT collaboration, and continuous improvement by allowing user modifications to running apps in a controlled way.
