You want to make three peanut butter and jelly sandwiches. What is the best way to make them that's consistent with an agile mindset? Create a sandwich assembly line, applying all the peanut butter first and then all the jelly. Completely finish each sandwich one at a time. Make one complete sandwich and split it in half for testers to try. Spread peanut butter on one side of all the sandwiches and ask for feedback.
