Unrepresentative Testing – The Papier Mâché Rhino

Unrepresentative Testing – Obvious flaws in simulation testing with a Papier Mâché Rhino at Tokyo’s Ueno Zoo.

INTRIGUING THINGS happen in Japan, but these scenes from Ueno Zoo in Tokyo are an extreme outlier in unrepresentative testing.

Rhinos (depending on species) range in weight from 750 pounds to 8,000 pounds and stand anywhere from four and a half to six feet tall. Rhinos can run up to 40 mph and turn 180 degrees in a distance equal to their body length.

Unrepresentative Testing on a Large Scale

In this simulation, an escaped rhino is used to test responder capabilities. The obvious flaw is the lack of realism. The rhino is a papier mâché model propelled by zoo staff.

This is a quintessential example of ‘unrepresentative testing’ and lends its name hereafter to the ‘Papier Mâché Rhino’ Anti Pattern.
