What we actually do, in the order we do it
Most of an automation engagement is arithmetic, not modelling. We count how many times a thing happens in a month, how many minutes each instance takes, who touches it, and what share falls out as an exception. Until those four numbers exist on paper, every later claim about savings is a guess wearing a spreadsheet.
Then we build the integration that removes the re-typing: an API where one exists, a scheduled job against a database where it does not, a parser for the file format your supplier will never stop emailing. Most of it is unglamorous code — queues, retries, idempotency keys, an audit trail somebody can read during a dispute.
The last step is the one that gets cut everywhere else. We re-measure with the same instrument, on the same process families, and write down the delta including the cases the automation refused to handle. A number produced by a different method than the baseline is not a result; it is a coincidence.
