Bev, who buys everything the job needs, places the escalator order, quoting the specification that came with the enquiry: C01. It's in her inbox, and it looks very official.
Ordered off the current revision

The escalators are ordered from me. Make sure it's the current me, not the one that came with the enquiry.
The wrong way
Designer Alex's firm had already put C02 on the published shelf. Heavier escalators, because the floors got taller.
Groundworks supervisor Nicole's gang starts on site. Nobody set up their logins, so they build from the prints in their own office.
Nicole: We've got drawings. We printed them in March.
The escalators arrive. Rex, the new assistant engineer, signs for them. They look like escalators. Stevie, the site engineer, checks the nameplates against the schedule. They're the wrong escalators.
Sam, the firm's information manager, holds up the spec from the published shelf. Bev holds up the one from her inbox.
Bev: I ordered what the spec said.
Sam: Which spec?
Sixteen more weeks for the right escalators, a restocking charge for the wrong ones, and the escalator pits are already cast for the old size.
The right escalators were on the published shelf. The order quoted the inbox.
+6 weeks on the back alley's bill: Escalators ordered off the old spec, and a gang building from March prints: the wrong escalators, sixteen weeks for new ones, and everything else moved round them.
