The lesson
Put your own analysis's blind spot on a slide, stamped, before anyone else finds it.
A Coca-Cola deck rebuilt by Pitch Unfairly opens as "Project Kansas" with "Pepsi is winning the sip. We can win it back." A later table gives Coke the check on advertising, vending, fountain and shelf space, and a blue row, "Blind taste test", reads "Loses". The SWOT slide adds a box, "What customers feel", empty and stamped "NOT MEASURED".
The soft-drink figures and the Pepsi framing are part of this story, so use your own numbers. Keep the interactive test, the single highlighted row and a named "not measured" box.
