✅ Improvement Suggestions
[MEDIUM] Process has no meaningful name
💡 Add a descriptive process name for better identification
🏗️ Camunda 8 Way: Use meaningful process names in BPMN
[MEDIUM] 3 User Task(s) have no forms defined
💡 Create and attach Camunda 8 forms to these user tasks
🏗️ Camunda 8 Way: Use Camunda 8 Forms with zeebe:formDefinition
