Appian

Appian brings together three capabilities in one platform, process automation (BPM), case management for handling exceptions, and RPA for legacy system integration. The unified designer lets you build processes that combine human judgment with automated steps, route work based on business rules, and manage long-running cases that evolve over time. This makes it stronger than pure automation for processes requiring approval loops, escalation, and human oversight.

The platform targets large enterprises with complex, mission-critical business processes. It's built for durability and scale, which means it comes with a learning curve and enterprise pricing. Organizations succeed when they're automating genuinely complex processes where the cost of the platform pays back quickly through labor savings and improved compliance.
