The scariest things in a drawing office.

Forget ghosts and vampires. If you want to frighten a detailer, try these.

1. "Superseded", on steel that's already cut

The drawing was issued. The workshop ran with it. Then the new revision arrived. Nobody screams louder than a fabricator holding a cut list for last week's drawing.

2. The Friday 4:55pm "quick change"

It is never quick. It is always Friday. It always starts with "can you just".

3. "Information coming tomorrow"

Sent three weeks ago. Still coming. Meanwhile the programme hasn't moved an inch.

4. "Which revision did we send them?"

Followed by a long silence and six people searching their inboxes at once.

5. The quote nobody chased

It was a good price. The client opened it seven times. Nobody called. Someone else did.

6. GAIL, dressed as a ghost

Our robot friend came to the office party as "the drawing that was issued without being checked". Nobody laughed. Too soon.

Keeping the monsters out

Most of these are the same monster: information in the wrong place. Redpen keeps every revision of a quote, and the job's RFIs and variations, where you can find them. It shows which quotes a client has opened, so the good ones get chased. It won't stop the 4:55pm phone call, but it does mean the change gets logged as a variation instead of vanishing.

Which one gave you the fright of your life? Tell us, and tag the colleague who survived it.
