Short answer

The right tool depends on your systems, data control, maintenance cost and process complexity.

How to approach it

Start with a process that repeats often, has a clear output and carries a measurable manual cost.

  • write down input and output
  • mark decisions and exceptions
  • assess sensitive data
  • decide who maintains the flow after launch

What to do next

If the process is repeatable and rule-based, prepare a small test scope instead of designing a large system immediately.
