I designed, built, and continue to maintain this Control-M solution for EDP. Reengineered fragile shell-based invoice processing into a resilient Control-M architecture — achieving the 46% incident reduction and 36% fewer ITOps requests documented in BMC's official case study, plus 90% less operational effort through architectural redesign.
The most important lesson was that re-engineering a monolithic batch chain isn't a technical project — it's a governance project. The technical decomposition took weeks. If I did it again, I'd start the ownership mapping before touching a single job definition. The second lesson: once teams saw what a properly orchestrated workload could do, feature requests multiplied — demand for Control-M capabilities grew faster than we could deliver. The tool wasn't the bottleneck. Organisational readiness was."
