Machine Learning does not change your role as a Product Manager and your role remains to talk to customers and communicating their problems to the technical team and business. Don’t build ML just for the sake of it as it is a large commitment and business investment. ML isn’t magic and it’s a customer delight feature. If you take the time to do it right, it can be game changing! Test with customers on weekly basis, run experiments, test hypothesis so you can learn quickly. Remember, the quicker you learn, the less risk you will be taking when launching to the wider customer base.
