Answer
A workflow that quietly diverges from its approved design is a common failure pattern: someone modifies a step during an incident to work around a problem, the fix works, and the change never gets formally reviewed or documented because the pressure was on getting production running again. Six months later, nobody remembers that the workflow no longer matches what was originally approved, and when an auditor or a new team member asks why a particular step exists, there is no clean answer. On IBM i systems where automation touches financial postings or trading partner data, that kind of undocumented drift is exactly what turns into an audit finding.
Buyers should ask vendors whether workflow changes require a defined approval step before going live, whether the platform keeps version history so a prior configuration can be compared or restored, and whether every execution log ties back to the specific version of the workflow that ran. It is also worth asking how long execution history is retained, since some platforms purge detailed logs after a short window to save storage, which can leave a gap right when an auditor asks about an event from several months earlier. A platform that treats its own change history as seriously as it treats the jobs it runs is the one worth trusting with production-critical automation.
