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.

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.
