This weekend I hopped on a 100 year old trolley train operated by volunteers in our city. There are two trolleys that operate, and when it comes to both of them crossing the high level bridge over the river, there's a problem...

They only have one track to get over.

So how do they communicate who has the right away?

They leverage an old strategy known as Poka Yoke (or "mistake proofing") - and the trick that they use is SIMPLE.

Find out about the simple trick they use, and how you can apply similar thinking and systems in your business to help prevent you and your team from making mistakes.
