Answer:
<em>A hypothesis is a testable, scientific statement</em> based upon limited evidence as a starting point in order for further investigation.
I assume when you ask <em>during which steps is it important</em> you mean the steps of the scientific method. Although it is important throughout the entire process, the most important would probably making a prediction. You cannot make a (good) prediction without a hypothesis. And without a prediction, you cannot test anything at all. You can't form a conclusion of any sorts.
So I would say it is most important when trying to form a prediction based on your hypothesis.
