A job here usually starts in one system and finishes in another. The booking is in the scheduler, the deposit is in the point-of-sale, the invoice is in accounting, and the customer thread is in email, so the same name, address and price get entered four times by four people who each trust a different screen.
That is the work worth looking at first in Farmingdale, because it repeats on every job and it is nobody's actual job. The assessment follows one job end to end, where each fact first appears, who re-enters it, where it waits, who has final say, and names the steps that must stay under a person's control before anything is built.
The pattern is written out in full in when good business tools do not talk, with the hand-offs that can be handed over marked separately from the ones that need a person reading them.
