IBM Business Automation Workflow runs processes and cases on WebSphere or in containers as part of IBM Cloud Pak for Business Automation. Pages here cover replacing it with self-hosted Flowable or Operaton.
Comparing IBM Business Automation Workflow with Flowable for process and case work: BPMN processes, CMMN cases and DMN decisions in Flowable's engines, the UI and authoring tools IBM bundles that Flowable's open-source edition leaves out, and operating each.
For BPM teams comparing IBM Business Automation Workflow with Operaton, the community fork of Camunda 7: BPMN and DMN execution, REST API and embedded Java use, half-yearly releases without an LTS line, and support from independent providers instead of IBM.
Moving from IBM Business Automation Workflow to Flowable: inventorying process apps, toolkits and case solutions, redrawing processes in BPMN and cases in CMMN, replacing coaches with your own UI, draining in-flight instances and retiring the WebSphere or Cloud Pak estate.
Cost of ownership by component: Cloud Pak for Business Automation licensing and the WebSphere or OpenShift platform under it, against Flowable's open-source engines or commercial editions, servers, rebuild effort, UI development and support.
For teams on Cloud Pak for Business Automation 23.0.x or 24.0.x: what the lifecycle dates and extended support mean, the cost and effort of the next upgrade, and when moving to an open-source engine is the better use of that project.
For estates still on the WebSphere-based traditional runtime: what moving to the Liberty-based container runtime involves, which artifacts do not carry over, and how that migration compares with rebuilding on Flowable or Operaton running on standard Java.
Replacing Business Automation Workflow case solutions, the successor to IBM Case Manager style work, with Flowable's CMMN engine: case types, stages and milestones, documents kept in your own content store, and the case UI you will need to build.
