 Scale number four is execution skills. This is very specific to consultant and MBA students. I know 90% of consultants only do certain section of the product or project and you never watch it end to end. But this is critical for product managers because we need to see a product from concept to execution. So I recommend all of you guys start to figure out in your current experience what kind of product you have built, which is one side of product management, but you're missing the other side such as GTN or engineering facing type of project. So therefore I will focus on the part you do not know.
