Observational Research

Observational Research is a good tactic for Mike to use. Looking who and what people buy will help him improve is product line. If he sees people wanting something selling well he might make a limited addition having the consumer want to buy it before it is gone. Or even what's not selling so well and maybe do something else in place of that item. This way he can branch out as well and know what people like or dislike  . . . . . what would be a successful sale and what he might be wasting his time on.
