The automation programs that stick share a common set of design principles. The ones that fail share a different set.
Finance automation programs succeed when they are treated as engineering programs. That means version control, environments, code review, testing, and observability — the same discipline applied to any other production system.
The most durable automations are built on top of a governed data platform, not on top of screen scraping and brittle RPA scripts. Every hour spent on the platform pays back tenfold on the automations that sit on it.
Finally, automations need owners. An automation without a named engineer accountable for it is a future incident waiting for a bad month-end.
