Redline

A real-looking document with several things wrong, and three edits to spend on it. Passages you could change are underlined — and some of them are fine, so fixing one costs an edit and buys nothing. Commit, and each passage is scored for what it was actually worth, with the reason and a suggested fix. Marking every flaw is not the exercise; anyone can do that with a red pen and enough time. Choosing which two or three carry the weight is the job. Works alone at a desk as well as on a screen with a room arguing. Five looks ship with it — the activity’s own, plus an archive, a workshop, a museum and a winter market, drawn in the file itself with no images to load.

Problem

Spotting flaws is easy and close to useless — give anyone a red pen and enough time and they will mark everything, including the parts that were working. What nobody practises is deciding which changes carry the weight and being willing to leave the rest, which is the actual constraint in every real review.

Who it helps

Anyone who reviews written work — process documentation, customer correspondence, policy, job aids — and teams being taught to give feedback that is worth receiving.

In training

The decoys are the lesson, so do not warn anyone they exist. The instinct to tidy a passage that reads oddly is strong and it spends attention the real problems needed — if someone burns an edit on a working sentence, that is the most useful thing that will happen in the session. Finish by asking what made the decoy look wrong, because the answer is usually style rather than consequence.
