Why is a drawing a sketch an important part of the scientific method and why do you always neglect this step!?!?

I think drawing a sketch is important. It gives you a better idea of understanding the question. Drawing a sketch also gives you a better idea of what you are building. When you draw out a sketch you know which direction you are going, and then you can work faster and better while you are doing the project. I think sometimes we neglect this step, because some times we don't fallow the sketch that we draw, because the sketch it self is too hard to be built. And sometimes we just want to built it first then fix it later.
