How do you make your product decisions? Intuition or Data? Do you use any tools?

If you're not using data, you're just guessing.

Using the collected data to implement

Nowadays, given the head-spinning number of products that are coming out every single day, going out on an hunch will probably be a waste of time on the majority of occasions. Data, especially user-generated information, can be a reliable parameter, but I think first-hand experience and a trial run is positively the most useful source of information for making a decision. At times, some products might be very efficient but not suitable to your specific needs.
