 to have customer empathy and customer interview skills. I know majority of the consultant MBAs, you guys are very good at making the strategies and PowerPoint presentations. But once we dive into your strategies, how did you get those results? You may only talk to a few people and come out with grand vision, five year plan. To be honest, as a product manager, we work reversely. We use an agile approach. We want to understand what is a pain point? Why they make such a decision? And on top of that, how can we start to help them solve problems today? And we will do AB testing, rolling out MEPs, a different kind of smaller set for customers to start to solve their problems and also test out our product idea. Therefore I recommend consultant and MBA start to build customer empathy, to wear the shoes of customers during those pain point and start to contact customer interviews as well.
