Teams using Camunda often face challenges around complexity, integration, and scale. The first hurdle is the learning curve for BPMN/DMN modeling and for thinking in terms of explicit workflows rather than ad-hoc code, which can be difficult for both developers and business users. Process modeling itself can become messy if diagrams are overloaded or not well-structured, leading to confusion and maintenance issues. Integrating Camunda with legacy systems, microservices, and existing APIs can also be challenging and usually requires careful design of interfaces, error handling, and data mapping. At higher volumes, teams may struggle with performance and scalability, needing to tune the engine, database, and infrastructure. Finally, ensuring governance, versioning, and team adoption—clear standards, review practices, and monitoring—can be difficult but is critical for long-term success with Camunda.
