Read the following paragraph from the introduction [paragraphs 1-3]. The engineering design process has many steps. Engineers do not always follow them in order. You might design something, test it and find a problem. When this happens, go back to an earlier step. Make a change to your design. This way of working is called iteration. This means repeating steps to get closer to your final solution.

What is the MAIN idea of this paragraph
