Another good technique that is used in the Industry is: Failure Mode Effects Analysis (FMEA)

This technique analyses the outcomes of a failing project. First you establish the failure modes, then risk reduction is used in order to increase the possibility of the product’s success. So pretty much you delete any failure possibility in the product. This technique let’s you summarize what are the most important features of the product, from that point the researchers can cut/add whatever is needed to increment the quality of the product. My uncle works in the computer Engineering Industry and he has mentioned to me that they have used this technique multiple times.

Let me know what you think
