Analysis ask the question what so that it will be easier to break down what we want to do into various unit in order to have good conclusion. It should be noted that an analysis could be statistical in nature which is very common among various types of analysis.
Design on the other hand, is about modeling how that behavior may be implemented. This is very crucial because it will be easier to gather plan, or the look of the product that the design will produced at the end of the design.
