Problem: Let's examine the influence of this poka-yoke concept on society. Spend some time thinking about mistake-proofing the world we live in. Find a "real life" example of poke-yoke and take a picture of it. Create a new discussion thread, attach your picture, and describe your find. What type of mistake does your find prevent us from making? Is this a relatively new approach to the problem or is it something that's been around for a while?
