A training example that I do with my shop kids in school is something I stole from you tube. It's called the peanut butter and jelly sandwich challenge.
I use it as a tool to show my students how detailed their blueprints for their projects should be.
How this usually goes is I start the class by asking the students to write on a piece of paper how to make a peanut butter and jelly sandwich. I tell them to write it like the person has never made one before. I give them 1 minute for the first draft. Then once the minute is up I have them show me what they have and I follow the directions exactly. No one gets a peanut butter and jelly sandwich because the directions are terrible. After this I give them 10 minutes and challenge them to see if they can get a peanut butter and jelly sandwich. This teaches them that good "Blueprints" don't take only a minute and most of the time they don't take 10 minutes. This helps to slow them down and think through the project that they are going to do.
