Gawd! *Every* bit of repeated routine processing I do I ensure is written down as an "aircraft cockpit" step list. *Including* the steps that don't involve the computer, such as: Obtain new user's prefered name, note as name/surname pair, ensure this is correct, *EVERYTHING* will be copy'n'pasted from this.
I tear my hair out at the horrifying number of cases where people *type* *in* the same data repeatedly, adding in their own unique errors every time. Get it in the computer *ONCE*, then use that. Do. Not. repeatedly process it through somebody's brain.
